A Review on the principle of Dental Management of
the Pregnant patient
Dr A K M Tanzir Hasan
bull Pregnancy has been considered an impediment to dental treatment However preventive emergency and routine dental procedures are all suitable during various phases of a pregnancy with some treatment modifications and initial planning
Questions that a dentist may askbull Can I take x-rays
bull Can I inject local anesthesia with epinephrine
bull What medications can I prescribe
bull Are topical agents safe
bull When should I perform necessary procedures
bull Can I use mercury restorations
Stages of Pregnancy
bull1st Trimester (1-12 weeks)
bullFetal organ formation and differentiation
bullMost susceptible to adverse effects of teratogens
bullAvoid all elective care but provide care as needed
Stages of Pregnancy
bull2nd Trimester (13-24 weeks)
bullFetal growth and maturation
bullSafest period to provide dental care
Stages of Pregnancy
bull3rd Trimester (25-40 weeks)
bullFetal growth continues
bullFocus of concern is risk to upcoming birth process and safety and comfort of the pregnant woman
Physiologic Changes in Pregnancy
bull Complex hormonal interactions cause profound physiologic changes
bull Increase estrogen by 10 fold and progesterone by 30 folds
bull Increased hormonal secretion and fetal growth causes several systemic as well as physical changes in a pregnant women
Systemic changes in pregnancy
Cardiovascular system uarr in blood volume by an average of 45bull Anemia due to increased blood volume
(20 of women) darr in pulse by 10-15 beats per minute Systemic murmur occurs in 90 of
pregnancies disappears shortly after delivery
uarrcardiac output Supine hypotension syndrome may
occur
FLAT SUPINE POSITIONING
bullNegatively impacts mother and infant
SUPINE HYPOTENSIONSYNDROME (Vena Cava Compression)
bull SUPINE POSITION AFTER 5TH MONTH
bull UTERUS COMPRESSES THE INFERIOR VENA CAVA
bull uarrVOL BLOOD IN THE LErsquoS
bull darrRETURN TO THE HEART
bull REDUCED PERFUSION OF UTERUS
bull FETAL HYPOXIA
Supine Hypotension Syndrome
bull Obstruction of inferior vena cava and aorta from pressure of the large fetus
Symptoms
Sweating
Nausea
Weakness
Sense of lack of air
Supine Hypotension Syndrome
Other symptoms
bull Drop in blood pressure
bull Bradycardia
bull Possible loss of consciousness
Prevention of Supine HypotensiveSyndrome
bullElevate right hip 10-12 cm
bullWeight is taken off the major vessels
Treatment of Supine HypotensiveSyndrome
bullRoll patient onto her left side
How should the pregnant woman be positionedbull Flat position may
cause hypotension and hypoxia
bull Place a small pillow under right hip - left lateral displacement
bull Head above feet
Systemic changes in pregnancy
Diaphragm rises about 4 cm darr residual volume uarr awareness of a desire to breath is
common-may be interpreted as dyspnea Increased estrogen in blood causes
engorgement of the nasal capillaries and rhnitis in pregnant women
Frequent nosebleeds amp predisposition to upper respiratory infection
Respiratory system
Systemic changes in pregnancy
Gastrointestinal system Gastric emptying amp intestinal transit times
are delayed
Heart burn reflux common
Nausea and vomiting common
Systemic changes in pregnancy
For pregnant patient with Hyper-emesis gravidarium ( excessive and uncontrolled vomiting) morning appointments should be avoided
They should be seated in a semi-supine or comfortable position
In case of vomiting the procedure should be stopped immediately amp the patient should be repositioned upright
When vomiting is over rinsing mouth with cold water or mouthwash is recommended
Systemic changes in pregnancy
bull Urinary System uarr GFR amp renal plasma flow by as much as
50 Nocturia ndashto mobilize the dependent
edema which accumulate during the day uarr Frequency from uarr renal flow plus reduced
bladder capacity from uterine growth It is advisable to ask the patient to void the
bladder just prior to starting the dental procedure
Systemic changes in pregnancy
Endocrine Changes uarrEstrogen uarr progesterone uarrhuman
gonadotropin uarr thyroxin steroid and insulin level Estrogen amp progesterone are insulin
antagonists uarr level of these hormones lead to insulin resistance Thus insulin levels are elevated in pregnant in pregnant patient to compensate this resistance
About 45 of women fail to produce sufficient amount of insulin to overcome this antagonist action amp thus develop gestational diabetes
Systemic changes in pregnancy
Hematological changebull uarr red RBC uarrESR darrHbbull uarrWBCbull uarr circulatory catecholamin amp cortisol lead
to leucositosis bull uarr Coagulation factors except factor XI amp
XIII (anticloting factor) bull so pregnancy is a hypercoagulable state amp
uarr risk for thromboembolism
Systemic changes in pregnancy
bull Pregnant women with anti-phospholipid syndrome are at uarr risk for thrombo-embolisim
bull They are placed on subcutaneous low molecular weight heparin (LMWH)
bull These patients must be hospitalized for dental care
Pregnancy RelatedOral Health Problems
bull Pregnancy Gingivitisbull Pregnancy Epulis bull Increased Tooth Mobilitybull Dental Cariesbull Erosionbull Dental Problems in relation to Labor
and Delivery
Oral Problems in Pregnancy
bullPregnancy GingivitisbullMost common oral manifestation (50-100 of women)bullCaused by hormonal and vascular changes of pregnancy
Pregnancy Gingivitis Pathophysiology
bull Elevated circulating estrogen increases capillary permeability
bull Preexisting gingivitis may predispose to pregnancy gingivitis
Pregnancy Gingivitis
bullOccurs commonly in the 2nd to 8th months
bullTendency to bleed very easily
bullTreatment Scaling root-planing currettage OHI
Pregnancy Granuloma
bullOccurs in up to 5 of women
bullMost common in buccal maxillary anterior areas
bullUsually starts in an area of gingivitis
Pregnancy Granuloma (continued)
bullRapid growth up to 2 cm
bullSingle tumor-like growth
bullusually in interdental papillae
bullPurplish to bluish in color may be ulcerated- bleeds easily
Gum Problems - Pregnancy Granuloma
Gum Problems - Pregnancy Granuloma
Gum Changes - Pregnancy Granuloma
Pregnancy Granuloma (continued)
Treatment
bull Scaling and root planing
bull Excision if it is too large or bleeds too easily
bull May regress spontaneously after pregnancy
Candidiasis
bullWipes offbullUsually asymptomatic but may burnbullTreatment topical or systemic antifungals
Pregnancy Myths
bullldquoA mother loses a tooth for every babyrdquobullNo evidence that aphthous ulcers are any more common in pregnancy
Other Oral Conditions in Pregnancy
bull Dry mouth
bull Excessive salivation
bull Tooth erosions associated with severe GERD or hyperemesis
Changes During Pregnancy that Affect Oral Health
bull Hormonal Affects
ndash Increased tooth mobility
ndash Saliva changes
ndash Increased bacteria
ndash Gingival problems
Saliva changesbull Decreased buffers
bull Decreased minerals
bull Decreasing flow first and last trimester
bull Increased flow second trimester
bull More acidic
Increased Bacteriabull Increased acidity
ndash Increase in decay-causing bacteria
bull Increased Snackingndash Morning sicknesslow blood sugar
ndash Between-meal snacks
bull Increase in amount and frequency of starchescarbohydrates ndash Crackers are commonly recommended
ndash Promotes decay-causing bacteria
Changes During Pregnancy that Affect Oral Health
bull Morning sicknessndash Difficulty with hygiene
bull Gingival diseasebull Tooth decay
ndash Vomiting
bull Esophogeal Reflux (heartburn)bull Acid exposure
ndash Irritation of the gumsndash Weakening of tooth enamelndash Dental erosion
Enamel erosion caused by frequent vomiting
Treatment for Acid Exposure
bull Do NOT brush immediately after vomiting
bull Rinse
ndash Water with baking soda
ndash Antacid
ndash Plain water
bull Eat some cheese
Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms
FDA drug classification for pregnancy
bull D = There is evidence of human fetal risk but benefits may outweigh risks
FDA drug classification for pregnancy
bull X = Contraindicated
Common Analgesics
bull paracetamol (B)
bull Ibuprofen (BD)
bull Oxycodone (BD)
bull Hydrocodone and codeine (CD)
avoid in third trimester
Analgesics
bull Paracetamol is the analgesic of choice for all stages of gestation
bull used to treat mild to moderate pain and fevers
bull short term usage is believed to be safe
bull avoid chronic and large doses of paracetamol
1048715
Analgesics - continued
bull Aspirin is nonteratogenic but may cause maternal and fetal hemorrhage
bull large and chronic doses during last trimester may result in premature closure of ductus arteriosus fetal hypertension anemia and low birth weight
bull avoid ibuprofen in 3rd trimester because of possible adverse circulatory effects
bull short term use of codeine seems safebull avoid codeine late in gestation because of
possible fetal respiratory depression and withdrawal symptoms
Analgesics to Use During1st and 2nd Trimester
bull Category B (for best)
bull Paracetamol Ibuprofen
bull Naproxen
bull Category C (use with caution)
bull Paracetamol with codeine or hydrocodone

Thank you
bull Pregnancy has been considered an impediment to dental treatment However preventive emergency and routine dental procedures are all suitable during various phases of a pregnancy with some treatment modifications and initial planning
Questions that a dentist may askbull Can I take x-rays
bull Can I inject local anesthesia with epinephrine
bull What medications can I prescribe
bull Are topical agents safe
bull When should I perform necessary procedures
bull Can I use mercury restorations
Stages of Pregnancy
bull1st Trimester (1-12 weeks)
bullFetal organ formation and differentiation
bullMost susceptible to adverse effects of teratogens
bullAvoid all elective care but provide care as needed
Stages of Pregnancy
bull2nd Trimester (13-24 weeks)
bullFetal growth and maturation
bullSafest period to provide dental care
Stages of Pregnancy
bull3rd Trimester (25-40 weeks)
bullFetal growth continues
bullFocus of concern is risk to upcoming birth process and safety and comfort of the pregnant woman
Physiologic Changes in Pregnancy
bull Complex hormonal interactions cause profound physiologic changes
bull Increase estrogen by 10 fold and progesterone by 30 folds
bull Increased hormonal secretion and fetal growth causes several systemic as well as physical changes in a pregnant women
Systemic changes in pregnancy
Cardiovascular system uarr in blood volume by an average of 45bull Anemia due to increased blood volume
(20 of women) darr in pulse by 10-15 beats per minute Systemic murmur occurs in 90 of
pregnancies disappears shortly after delivery
uarrcardiac output Supine hypotension syndrome may
occur
FLAT SUPINE POSITIONING
bullNegatively impacts mother and infant
SUPINE HYPOTENSIONSYNDROME (Vena Cava Compression)
bull SUPINE POSITION AFTER 5TH MONTH
bull UTERUS COMPRESSES THE INFERIOR VENA CAVA
bull uarrVOL BLOOD IN THE LErsquoS
bull darrRETURN TO THE HEART
bull REDUCED PERFUSION OF UTERUS
bull FETAL HYPOXIA
Supine Hypotension Syndrome
bull Obstruction of inferior vena cava and aorta from pressure of the large fetus
Symptoms
Sweating
Nausea
Weakness
Sense of lack of air
Supine Hypotension Syndrome
Other symptoms
bull Drop in blood pressure
bull Bradycardia
bull Possible loss of consciousness
Prevention of Supine HypotensiveSyndrome
bullElevate right hip 10-12 cm
bullWeight is taken off the major vessels
Treatment of Supine HypotensiveSyndrome
bullRoll patient onto her left side
How should the pregnant woman be positionedbull Flat position may
cause hypotension and hypoxia
bull Place a small pillow under right hip - left lateral displacement
bull Head above feet
Systemic changes in pregnancy
Diaphragm rises about 4 cm darr residual volume uarr awareness of a desire to breath is
common-may be interpreted as dyspnea Increased estrogen in blood causes
engorgement of the nasal capillaries and rhnitis in pregnant women
Frequent nosebleeds amp predisposition to upper respiratory infection
Respiratory system
Systemic changes in pregnancy
Gastrointestinal system Gastric emptying amp intestinal transit times
are delayed
Heart burn reflux common
Nausea and vomiting common
Systemic changes in pregnancy
For pregnant patient with Hyper-emesis gravidarium ( excessive and uncontrolled vomiting) morning appointments should be avoided
They should be seated in a semi-supine or comfortable position
In case of vomiting the procedure should be stopped immediately amp the patient should be repositioned upright
When vomiting is over rinsing mouth with cold water or mouthwash is recommended
Systemic changes in pregnancy
bull Urinary System uarr GFR amp renal plasma flow by as much as
50 Nocturia ndashto mobilize the dependent
edema which accumulate during the day uarr Frequency from uarr renal flow plus reduced
bladder capacity from uterine growth It is advisable to ask the patient to void the
bladder just prior to starting the dental procedure
Systemic changes in pregnancy
Endocrine Changes uarrEstrogen uarr progesterone uarrhuman
gonadotropin uarr thyroxin steroid and insulin level Estrogen amp progesterone are insulin
antagonists uarr level of these hormones lead to insulin resistance Thus insulin levels are elevated in pregnant in pregnant patient to compensate this resistance
About 45 of women fail to produce sufficient amount of insulin to overcome this antagonist action amp thus develop gestational diabetes
Systemic changes in pregnancy
Hematological changebull uarr red RBC uarrESR darrHbbull uarrWBCbull uarr circulatory catecholamin amp cortisol lead
to leucositosis bull uarr Coagulation factors except factor XI amp
XIII (anticloting factor) bull so pregnancy is a hypercoagulable state amp
uarr risk for thromboembolism
Systemic changes in pregnancy
bull Pregnant women with anti-phospholipid syndrome are at uarr risk for thrombo-embolisim
bull They are placed on subcutaneous low molecular weight heparin (LMWH)
bull These patients must be hospitalized for dental care

Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes

Stages of Pregnancy
bull1st Trimester (1-12 weeks)
bullFetal organ formation and differentiation
bullMost susceptible to adverse effects of teratogens
bullAvoid all elective care but provide care as needed
Stages of Pregnancy
bull2nd Trimester (13-24 weeks)
bullFetal growth and maturation
bullSafest period to provide dental care
Stages of Pregnancy
bull3rd Trimester (25-40 weeks)
bullFetal growth continues
bullFocus of concern is risk to upcoming birth process and safety and comfort of the pregnant woman
Physiologic Changes in Pregnancy
bull Complex hormonal interactions cause profound physiologic changes
bull Increase estrogen by 10 fold and progesterone by 30 folds
bull Increased hormonal secretion and fetal growth causes several systemic as well as physical changes in a pregnant women
Systemic changes in pregnancy
Cardiovascular system uarr in blood volume by an average of 45bull Anemia due to increased blood volume
(20 of women) darr in pulse by 10-15 beats per minute Systemic murmur occurs in 90 of
pregnancies disappears shortly after delivery
uarrcardiac output Supine hypotension syndrome may
occur
FLAT SUPINE POSITIONING
bullNegatively impacts mother and infant
SUPINE HYPOTENSIONSYNDROME (Vena Cava Compression)
bull SUPINE POSITION AFTER 5TH MONTH
bull UTERUS COMPRESSES THE INFERIOR VENA CAVA
bull uarrVOL BLOOD IN THE LErsquoS
bull darrRETURN TO THE HEART
bull REDUCED PERFUSION OF UTERUS
bull FETAL HYPOXIA
Supine Hypotension Syndrome
bull Obstruction of inferior vena cava and aorta from pressure of the large fetus
Symptoms
Sweating
Nausea
Weakness
Sense of lack of air
Supine Hypotension Syndrome
Other symptoms
bull Drop in blood pressure
bull Bradycardia
bull Possible loss of consciousness
Prevention of Supine HypotensiveSyndrome
bullElevate right hip 10-12 cm
bullWeight is taken off the major vessels
Treatment of Supine HypotensiveSyndrome
bullRoll patient onto her left side
How should the pregnant woman be positionedbull Flat position may
cause hypotension and hypoxia
bull Place a small pillow under right hip - left lateral displacement
bull Head above feet
Systemic changes in pregnancy
Diaphragm rises about 4 cm darr residual volume uarr awareness of a desire to breath is
common-may be interpreted as dyspnea Increased estrogen in blood causes
engorgement of the nasal capillaries and rhnitis in pregnant women
Frequent nosebleeds amp predisposition to upper respiratory infection
Respiratory system
Systemic changes in pregnancy
Gastrointestinal system Gastric emptying amp intestinal transit times
are delayed
Heart burn reflux common
Nausea and vomiting common
Systemic changes in pregnancy
For pregnant patient with Hyper-emesis gravidarium ( excessive and uncontrolled vomiting) morning appointments should be avoided
They should be seated in a semi-supine or comfortable position
In case of vomiting the procedure should be stopped immediately amp the patient should be repositioned upright
When vomiting is over rinsing mouth with cold water or mouthwash is recommended
Systemic changes in pregnancy
bull Urinary System uarr GFR amp renal plasma flow by as much as
50 Nocturia ndashto mobilize the dependent
edema which accumulate during the day uarr Frequency from uarr renal flow plus reduced
bladder capacity from uterine growth It is advisable to ask the patient to void the
bladder just prior to starting the dental procedure
Systemic changes in pregnancy
Endocrine Changes uarrEstrogen uarr progesterone uarrhuman
gonadotropin uarr thyroxin steroid and insulin level Estrogen amp progesterone are insulin
antagonists uarr level of these hormones lead to insulin resistance Thus insulin levels are elevated in pregnant in pregnant patient to compensate this resistance
About 45 of women fail to produce sufficient amount of insulin to overcome this antagonist action amp thus develop gestational diabetes
Systemic changes in pregnancy
Hematological changebull uarr red RBC uarrESR darrHbbull uarrWBCbull uarr circulatory catecholamin amp cortisol lead
to leucositosis bull uarr Coagulation factors except factor XI amp
XIII (anticloting factor) bull so pregnancy is a hypercoagulable state amp
uarr risk for thromboembolism
Systemic changes in pregnancy
bull Pregnant women with anti-phospholipid syndrome are at uarr risk for thrombo-embolisim
bull They are placed on subcutaneous low molecular weight heparin (LMWH)
bull These patients must be hospitalized for dental care

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births

Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage

Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including

Thank you
Stages of Pregnancy
bull1st Trimester (1-12 weeks)
bullFetal organ formation and differentiation
bullMost susceptible to adverse effects of teratogens
bullAvoid all elective care but provide care as needed
Stages of Pregnancy
bull2nd Trimester (13-24 weeks)
bullFetal growth and maturation
bullSafest period to provide dental care
Stages of Pregnancy
bull3rd Trimester (25-40 weeks)
bullFetal growth continues
bullFocus of concern is risk to upcoming birth process and safety and comfort of the pregnant woman
Physiologic Changes in Pregnancy
bull Complex hormonal interactions cause profound physiologic changes
bull Increase estrogen by 10 fold and progesterone by 30 folds
bull Increased hormonal secretion and fetal growth causes several systemic as well as physical changes in a pregnant women
Systemic changes in pregnancy
Cardiovascular system uarr in blood volume by an average of 45bull Anemia due to increased blood volume
(20 of women) darr in pulse by 10-15 beats per minute Systemic murmur occurs in 90 of
pregnancies disappears shortly after delivery
uarrcardiac output Supine hypotension syndrome may
occur
FLAT SUPINE POSITIONING
bullNegatively impacts mother and infant
SUPINE HYPOTENSIONSYNDROME (Vena Cava Compression)
bull SUPINE POSITION AFTER 5TH MONTH
bull UTERUS COMPRESSES THE INFERIOR VENA CAVA
bull uarrVOL BLOOD IN THE LErsquoS
bull darrRETURN TO THE HEART
bull REDUCED PERFUSION OF UTERUS
bull FETAL HYPOXIA
Supine Hypotension Syndrome
bull Obstruction of inferior vena cava and aorta from pressure of the large fetus
Symptoms
Sweating
Nausea
Weakness
Sense of lack of air
Supine Hypotension Syndrome
Other symptoms
bull Drop in blood pressure
bull Bradycardia
bull Possible loss of consciousness
Prevention of Supine HypotensiveSyndrome
bullElevate right hip 10-12 cm
bullWeight is taken off the major vessels
Treatment of Supine HypotensiveSyndrome
bullRoll patient onto her left side
How should the pregnant woman be positionedbull Flat position may
cause hypotension and hypoxia
bull Place a small pillow under right hip - left lateral displacement
bull Head above feet
Systemic changes in pregnancy
Diaphragm rises about 4 cm darr residual volume uarr awareness of a desire to breath is
common-may be interpreted as dyspnea Increased estrogen in blood causes
engorgement of the nasal capillaries and rhnitis in pregnant women
Frequent nosebleeds amp predisposition to upper respiratory infection
Respiratory system
Systemic changes in pregnancy
Gastrointestinal system Gastric emptying amp intestinal transit times
are delayed
Heart burn reflux common
Nausea and vomiting common
Systemic changes in pregnancy
For pregnant patient with Hyper-emesis gravidarium ( excessive and uncontrolled vomiting) morning appointments should be avoided
They should be seated in a semi-supine or comfortable position
In case of vomiting the procedure should be stopped immediately amp the patient should be repositioned upright
When vomiting is over rinsing mouth with cold water or mouthwash is recommended
Systemic changes in pregnancy
bull Urinary System uarr GFR amp renal plasma flow by as much as
50 Nocturia ndashto mobilize the dependent
edema which accumulate during the day uarr Frequency from uarr renal flow plus reduced
bladder capacity from uterine growth It is advisable to ask the patient to void the
bladder just prior to starting the dental procedure
Systemic changes in pregnancy
Endocrine Changes uarrEstrogen uarr progesterone uarrhuman
gonadotropin uarr thyroxin steroid and insulin level Estrogen amp progesterone are insulin
antagonists uarr level of these hormones lead to insulin resistance Thus insulin levels are elevated in pregnant in pregnant patient to compensate this resistance
About 45 of women fail to produce sufficient amount of insulin to overcome this antagonist action amp thus develop gestational diabetes
Systemic changes in pregnancy
Hematological changebull uarr red RBC uarrESR darrHbbull uarrWBCbull uarr circulatory catecholamin amp cortisol lead
to leucositosis bull uarr Coagulation factors except factor XI amp
XIII (anticloting factor) bull so pregnancy is a hypercoagulable state amp
uarr risk for thromboembolism
Systemic changes in pregnancy
bull Pregnant women with anti-phospholipid syndrome are at uarr risk for thrombo-embolisim
bull They are placed on subcutaneous low molecular weight heparin (LMWH)
bull These patients must be hospitalized for dental care

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms

Stages of Pregnancy
bull2nd Trimester (13-24 weeks)
bullFetal growth and maturation
bullSafest period to provide dental care
Stages of Pregnancy
bull3rd Trimester (25-40 weeks)
bullFetal growth continues
bullFocus of concern is risk to upcoming birth process and safety and comfort of the pregnant woman
Physiologic Changes in Pregnancy
bull Complex hormonal interactions cause profound physiologic changes
bull Increase estrogen by 10 fold and progesterone by 30 folds
bull Increased hormonal secretion and fetal growth causes several systemic as well as physical changes in a pregnant women
Systemic changes in pregnancy
Cardiovascular system uarr in blood volume by an average of 45bull Anemia due to increased blood volume
(20 of women) darr in pulse by 10-15 beats per minute Systemic murmur occurs in 90 of
pregnancies disappears shortly after delivery
uarrcardiac output Supine hypotension syndrome may
occur
FLAT SUPINE POSITIONING
bullNegatively impacts mother and infant
SUPINE HYPOTENSIONSYNDROME (Vena Cava Compression)
bull SUPINE POSITION AFTER 5TH MONTH
bull UTERUS COMPRESSES THE INFERIOR VENA CAVA
bull uarrVOL BLOOD IN THE LErsquoS
bull darrRETURN TO THE HEART
bull REDUCED PERFUSION OF UTERUS
bull FETAL HYPOXIA
Supine Hypotension Syndrome
bull Obstruction of inferior vena cava and aorta from pressure of the large fetus
Symptoms
Sweating
Nausea
Weakness
Sense of lack of air
Supine Hypotension Syndrome
Other symptoms
bull Drop in blood pressure
bull Bradycardia
bull Possible loss of consciousness
Prevention of Supine HypotensiveSyndrome
bullElevate right hip 10-12 cm
bullWeight is taken off the major vessels
Treatment of Supine HypotensiveSyndrome
bullRoll patient onto her left side
How should the pregnant woman be positionedbull Flat position may
cause hypotension and hypoxia
bull Place a small pillow under right hip - left lateral displacement
bull Head above feet
Systemic changes in pregnancy
Diaphragm rises about 4 cm darr residual volume uarr awareness of a desire to breath is
common-may be interpreted as dyspnea Increased estrogen in blood causes
engorgement of the nasal capillaries and rhnitis in pregnant women
Frequent nosebleeds amp predisposition to upper respiratory infection
Respiratory system
Systemic changes in pregnancy
Gastrointestinal system Gastric emptying amp intestinal transit times
are delayed
Heart burn reflux common
Nausea and vomiting common
Systemic changes in pregnancy
For pregnant patient with Hyper-emesis gravidarium ( excessive and uncontrolled vomiting) morning appointments should be avoided
They should be seated in a semi-supine or comfortable position
In case of vomiting the procedure should be stopped immediately amp the patient should be repositioned upright
When vomiting is over rinsing mouth with cold water or mouthwash is recommended
Systemic changes in pregnancy
bull Urinary System uarr GFR amp renal plasma flow by as much as
50 Nocturia ndashto mobilize the dependent
edema which accumulate during the day uarr Frequency from uarr renal flow plus reduced
bladder capacity from uterine growth It is advisable to ask the patient to void the
bladder just prior to starting the dental procedure
Systemic changes in pregnancy
Endocrine Changes uarrEstrogen uarr progesterone uarrhuman
gonadotropin uarr thyroxin steroid and insulin level Estrogen amp progesterone are insulin
antagonists uarr level of these hormones lead to insulin resistance Thus insulin levels are elevated in pregnant in pregnant patient to compensate this resistance
About 45 of women fail to produce sufficient amount of insulin to overcome this antagonist action amp thus develop gestational diabetes
Systemic changes in pregnancy
Hematological changebull uarr red RBC uarrESR darrHbbull uarrWBCbull uarr circulatory catecholamin amp cortisol lead
to leucositosis bull uarr Coagulation factors except factor XI amp
XIII (anticloting factor) bull so pregnancy is a hypercoagulable state amp
uarr risk for thromboembolism
Systemic changes in pregnancy
bull Pregnant women with anti-phospholipid syndrome are at uarr risk for thrombo-embolisim
bull They are placed on subcutaneous low molecular weight heparin (LMWH)
bull These patients must be hospitalized for dental care

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms

Stages of Pregnancy
bull3rd Trimester (25-40 weeks)
bullFetal growth continues
bullFocus of concern is risk to upcoming birth process and safety and comfort of the pregnant woman
Physiologic Changes in Pregnancy
bull Complex hormonal interactions cause profound physiologic changes
bull Increase estrogen by 10 fold and progesterone by 30 folds
bull Increased hormonal secretion and fetal growth causes several systemic as well as physical changes in a pregnant women
Systemic changes in pregnancy
Cardiovascular system uarr in blood volume by an average of 45bull Anemia due to increased blood volume
(20 of women) darr in pulse by 10-15 beats per minute Systemic murmur occurs in 90 of
pregnancies disappears shortly after delivery
uarrcardiac output Supine hypotension syndrome may
occur
FLAT SUPINE POSITIONING
bullNegatively impacts mother and infant
SUPINE HYPOTENSIONSYNDROME (Vena Cava Compression)
bull SUPINE POSITION AFTER 5TH MONTH
bull UTERUS COMPRESSES THE INFERIOR VENA CAVA
bull uarrVOL BLOOD IN THE LErsquoS
bull darrRETURN TO THE HEART
bull REDUCED PERFUSION OF UTERUS
bull FETAL HYPOXIA
Supine Hypotension Syndrome
bull Obstruction of inferior vena cava and aorta from pressure of the large fetus
Symptoms
Sweating
Nausea
Weakness
Sense of lack of air
Supine Hypotension Syndrome
Other symptoms
bull Drop in blood pressure
bull Bradycardia
bull Possible loss of consciousness
Prevention of Supine HypotensiveSyndrome
bullElevate right hip 10-12 cm
bullWeight is taken off the major vessels
Treatment of Supine HypotensiveSyndrome
bullRoll patient onto her left side
How should the pregnant woman be positionedbull Flat position may
cause hypotension and hypoxia
bull Place a small pillow under right hip - left lateral displacement
bull Head above feet
Systemic changes in pregnancy
Diaphragm rises about 4 cm darr residual volume uarr awareness of a desire to breath is
common-may be interpreted as dyspnea Increased estrogen in blood causes
engorgement of the nasal capillaries and rhnitis in pregnant women
Frequent nosebleeds amp predisposition to upper respiratory infection
Respiratory system
Systemic changes in pregnancy
Gastrointestinal system Gastric emptying amp intestinal transit times
are delayed
Heart burn reflux common
Nausea and vomiting common
Systemic changes in pregnancy
For pregnant patient with Hyper-emesis gravidarium ( excessive and uncontrolled vomiting) morning appointments should be avoided
They should be seated in a semi-supine or comfortable position
In case of vomiting the procedure should be stopped immediately amp the patient should be repositioned upright
When vomiting is over rinsing mouth with cold water or mouthwash is recommended
Systemic changes in pregnancy
bull Urinary System uarr GFR amp renal plasma flow by as much as
50 Nocturia ndashto mobilize the dependent
edema which accumulate during the day uarr Frequency from uarr renal flow plus reduced
bladder capacity from uterine growth It is advisable to ask the patient to void the
bladder just prior to starting the dental procedure
Systemic changes in pregnancy
Endocrine Changes uarrEstrogen uarr progesterone uarrhuman
gonadotropin uarr thyroxin steroid and insulin level Estrogen amp progesterone are insulin
antagonists uarr level of these hormones lead to insulin resistance Thus insulin levels are elevated in pregnant in pregnant patient to compensate this resistance
About 45 of women fail to produce sufficient amount of insulin to overcome this antagonist action amp thus develop gestational diabetes
Systemic changes in pregnancy
Hematological changebull uarr red RBC uarrESR darrHbbull uarrWBCbull uarr circulatory catecholamin amp cortisol lead
to leucositosis bull uarr Coagulation factors except factor XI amp
XIII (anticloting factor) bull so pregnancy is a hypercoagulable state amp
uarr risk for thromboembolism
Systemic changes in pregnancy
bull Pregnant women with anti-phospholipid syndrome are at uarr risk for thrombo-embolisim
bull They are placed on subcutaneous low molecular weight heparin (LMWH)
bull These patients must be hospitalized for dental care

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms

Physiologic Changes in Pregnancy
bull Complex hormonal interactions cause profound physiologic changes
bull Increase estrogen by 10 fold and progesterone by 30 folds
bull Increased hormonal secretion and fetal growth causes several systemic as well as physical changes in a pregnant women
Systemic changes in pregnancy
Cardiovascular system uarr in blood volume by an average of 45bull Anemia due to increased blood volume
(20 of women) darr in pulse by 10-15 beats per minute Systemic murmur occurs in 90 of
pregnancies disappears shortly after delivery
uarrcardiac output Supine hypotension syndrome may
occur
FLAT SUPINE POSITIONING
bullNegatively impacts mother and infant
SUPINE HYPOTENSIONSYNDROME (Vena Cava Compression)
bull SUPINE POSITION AFTER 5TH MONTH
bull UTERUS COMPRESSES THE INFERIOR VENA CAVA
bull uarrVOL BLOOD IN THE LErsquoS
bull darrRETURN TO THE HEART
bull REDUCED PERFUSION OF UTERUS
bull FETAL HYPOXIA
Supine Hypotension Syndrome
bull Obstruction of inferior vena cava and aorta from pressure of the large fetus
Symptoms
Sweating
Nausea
Weakness
Sense of lack of air
Supine Hypotension Syndrome
Other symptoms
bull Drop in blood pressure
bull Bradycardia
bull Possible loss of consciousness
Prevention of Supine HypotensiveSyndrome
bullElevate right hip 10-12 cm
bullWeight is taken off the major vessels
Treatment of Supine HypotensiveSyndrome
bullRoll patient onto her left side
How should the pregnant woman be positionedbull Flat position may
cause hypotension and hypoxia
bull Place a small pillow under right hip - left lateral displacement
bull Head above feet
Systemic changes in pregnancy
Diaphragm rises about 4 cm darr residual volume uarr awareness of a desire to breath is
common-may be interpreted as dyspnea Increased estrogen in blood causes
engorgement of the nasal capillaries and rhnitis in pregnant women
Frequent nosebleeds amp predisposition to upper respiratory infection
Respiratory system
Systemic changes in pregnancy
Gastrointestinal system Gastric emptying amp intestinal transit times
are delayed
Heart burn reflux common
Nausea and vomiting common
Systemic changes in pregnancy
For pregnant patient with Hyper-emesis gravidarium ( excessive and uncontrolled vomiting) morning appointments should be avoided
They should be seated in a semi-supine or comfortable position
In case of vomiting the procedure should be stopped immediately amp the patient should be repositioned upright
When vomiting is over rinsing mouth with cold water or mouthwash is recommended
Systemic changes in pregnancy
bull Urinary System uarr GFR amp renal plasma flow by as much as
50 Nocturia ndashto mobilize the dependent
edema which accumulate during the day uarr Frequency from uarr renal flow plus reduced
bladder capacity from uterine growth It is advisable to ask the patient to void the
bladder just prior to starting the dental procedure
Systemic changes in pregnancy
Endocrine Changes uarrEstrogen uarr progesterone uarrhuman
gonadotropin uarr thyroxin steroid and insulin level Estrogen amp progesterone are insulin
antagonists uarr level of these hormones lead to insulin resistance Thus insulin levels are elevated in pregnant in pregnant patient to compensate this resistance
About 45 of women fail to produce sufficient amount of insulin to overcome this antagonist action amp thus develop gestational diabetes
Systemic changes in pregnancy
Hematological changebull uarr red RBC uarrESR darrHbbull uarrWBCbull uarr circulatory catecholamin amp cortisol lead
to leucositosis bull uarr Coagulation factors except factor XI amp
XIII (anticloting factor) bull so pregnancy is a hypercoagulable state amp
uarr risk for thromboembolism
Systemic changes in pregnancy
bull Pregnant women with anti-phospholipid syndrome are at uarr risk for thrombo-embolisim
bull They are placed on subcutaneous low molecular weight heparin (LMWH)
bull These patients must be hospitalized for dental care

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms

Systemic changes in pregnancy
Diaphragm rises about 4 cm darr residual volume uarr awareness of a desire to breath is
common-may be interpreted as dyspnea Increased estrogen in blood causes
engorgement of the nasal capillaries and rhnitis in pregnant women
Frequent nosebleeds amp predisposition to upper respiratory infection

Systemic changes in pregnancy
Gastrointestinal system Gastric emptying amp intestinal transit times
are delayed
Heart burn reflux common
Nausea and vomiting common
Systemic changes in pregnancy
For pregnant patient with Hyper-emesis gravidarium ( excessive and uncontrolled vomiting) morning appointments should be avoided
They should be seated in a semi-supine or comfortable position
In case of vomiting the procedure should be stopped immediately amp the patient should be repositioned upright
When vomiting is over rinsing mouth with cold water or mouthwash is recommended
Systemic changes in pregnancy
bull Urinary System uarr GFR amp renal plasma flow by as much as
50 Nocturia ndashto mobilize the dependent
edema which accumulate during the day uarr Frequency from uarr renal flow plus reduced
bladder capacity from uterine growth It is advisable to ask the patient to void the
bladder just prior to starting the dental procedure
Systemic changes in pregnancy
Endocrine Changes uarrEstrogen uarr progesterone uarrhuman
gonadotropin uarr thyroxin steroid and insulin level Estrogen amp progesterone are insulin
antagonists uarr level of these hormones lead to insulin resistance Thus insulin levels are elevated in pregnant in pregnant patient to compensate this resistance
About 45 of women fail to produce sufficient amount of insulin to overcome this antagonist action amp thus develop gestational diabetes

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms
FDA drug classification for pregnancy
bull D = There is evidence of human fetal risk but benefits may outweigh risks
FDA drug classification for pregnancy
bull X = Contraindicated

Systemic changes in pregnancy
Diaphragm rises about 4 cm darr residual volume uarr awareness of a desire to breath is
common-may be interpreted as dyspnea Increased estrogen in blood causes
engorgement of the nasal capillaries and rhnitis in pregnant women
Frequent nosebleeds amp predisposition to upper respiratory infection

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms

Sense of lack of air
Supine Hypotension Syndrome
Other symptoms
bull Drop in blood pressure
bull Bradycardia
bull Possible loss of consciousness
Prevention of Supine HypotensiveSyndrome
bullElevate right hip 10-12 cm
bullWeight is taken off the major vessels
Treatment of Supine HypotensiveSyndrome
bullRoll patient onto her left side
How should the pregnant woman be positionedbull Flat position may
cause hypotension and hypoxia

Systemic changes in pregnancy
Diaphragm rises about 4 cm darr residual volume uarr awareness of a desire to breath is
common-may be interpreted as dyspnea Increased estrogen in blood causes
engorgement of the nasal capillaries and rhnitis in pregnant women
Frequent nosebleeds amp predisposition to upper respiratory infection
Respiratory system
Systemic changes in pregnancy
Gastrointestinal system Gastric emptying amp intestinal transit times
are delayed
Heart burn reflux common
Nausea and vomiting common
Systemic changes in pregnancy
For pregnant patient with Hyper-emesis gravidarium ( excessive and uncontrolled vomiting) morning appointments should be avoided
They should be seated in a semi-supine or comfortable position
In case of vomiting the procedure should be stopped immediately amp the patient should be repositioned upright
When vomiting is over rinsing mouth with cold water or mouthwash is recommended
Systemic changes in pregnancy
bull Urinary System uarr GFR amp renal plasma flow by as much as
50 Nocturia ndashto mobilize the dependent
edema which accumulate during the day uarr Frequency from uarr renal flow plus reduced
bladder capacity from uterine growth It is advisable to ask the patient to void the
bladder just prior to starting the dental procedure
Systemic changes in pregnancy
Endocrine Changes uarrEstrogen uarr progesterone uarrhuman
gonadotropin uarr thyroxin steroid and insulin level Estrogen amp progesterone are insulin
antagonists uarr level of these hormones lead to insulin resistance Thus insulin levels are elevated in pregnant in pregnant patient to compensate this resistance
About 45 of women fail to produce sufficient amount of insulin to overcome this antagonist action amp thus develop gestational diabetes
Systemic changes in pregnancy
Hematological changebull uarr red RBC uarrESR darrHbbull uarrWBCbull uarr circulatory catecholamin amp cortisol lead
to leucositosis bull uarr Coagulation factors except factor XI amp
XIII (anticloting factor) bull so pregnancy is a hypercoagulable state amp
uarr risk for thromboembolism
Systemic changes in pregnancy
bull Pregnant women with anti-phospholipid syndrome are at uarr risk for thrombo-embolisim
bull They are placed on subcutaneous low molecular weight heparin (LMWH)
bull These patients must be hospitalized for dental care

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester

Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms

Supine Hypotension Syndrome
Other symptoms
bull Drop in blood pressure
bull Bradycardia
bull Possible loss of consciousness
Prevention of Supine HypotensiveSyndrome
bullElevate right hip 10-12 cm
bullWeight is taken off the major vessels
Treatment of Supine HypotensiveSyndrome
bullRoll patient onto her left side
How should the pregnant woman be positionedbull Flat position may
cause hypotension and hypoxia

Systemic changes in pregnancy
Diaphragm rises about 4 cm darr residual volume uarr awareness of a desire to breath is
common-may be interpreted as dyspnea Increased estrogen in blood causes
engorgement of the nasal capillaries and rhnitis in pregnant women
Frequent nosebleeds amp predisposition to upper respiratory infection
Respiratory system
Systemic changes in pregnancy
Gastrointestinal system Gastric emptying amp intestinal transit times
are delayed
Heart burn reflux common
Nausea and vomiting common
Systemic changes in pregnancy
For pregnant patient with Hyper-emesis gravidarium ( excessive and uncontrolled vomiting) morning appointments should be avoided
They should be seated in a semi-supine or comfortable position
In case of vomiting the procedure should be stopped immediately amp the patient should be repositioned upright
When vomiting is over rinsing mouth with cold water or mouthwash is recommended
Systemic changes in pregnancy
bull Urinary System uarr GFR amp renal plasma flow by as much as
50 Nocturia ndashto mobilize the dependent
edema which accumulate during the day uarr Frequency from uarr renal flow plus reduced
bladder capacity from uterine growth It is advisable to ask the patient to void the
bladder just prior to starting the dental procedure
Systemic changes in pregnancy
Endocrine Changes uarrEstrogen uarr progesterone uarrhuman
gonadotropin uarr thyroxin steroid and insulin level Estrogen amp progesterone are insulin
antagonists uarr level of these hormones lead to insulin resistance Thus insulin levels are elevated in pregnant in pregnant patient to compensate this resistance
About 45 of women fail to produce sufficient amount of insulin to overcome this antagonist action amp thus develop gestational diabetes
Systemic changes in pregnancy
Hematological changebull uarr red RBC uarrESR darrHbbull uarrWBCbull uarr circulatory catecholamin amp cortisol lead
to leucositosis bull uarr Coagulation factors except factor XI amp
XIII (anticloting factor) bull so pregnancy is a hypercoagulable state amp
uarr risk for thromboembolism
Systemic changes in pregnancy
bull Pregnant women with anti-phospholipid syndrome are at uarr risk for thrombo-embolisim
bull They are placed on subcutaneous low molecular weight heparin (LMWH)
bull These patients must be hospitalized for dental care

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms
FDA drug classification for pregnancy
bull D = There is evidence of human fetal risk but benefits may outweigh risks
FDA drug classification for pregnancy
bull X = Contraindicated

Prevention of Supine HypotensiveSyndrome
bullElevate right hip 10-12 cm
bullWeight is taken off the major vessels
Treatment of Supine HypotensiveSyndrome
bullRoll patient onto her left side
How should the pregnant woman be positionedbull Flat position may
cause hypotension and hypoxia
bull Place a small pillow under right hip - left lateral displacement
bull Head above feet
Systemic changes in pregnancy
Diaphragm rises about 4 cm darr residual volume uarr awareness of a desire to breath is
common-may be interpreted as dyspnea Increased estrogen in blood causes
engorgement of the nasal capillaries and rhnitis in pregnant women
Frequent nosebleeds amp predisposition to upper respiratory infection
Respiratory system
Systemic changes in pregnancy
Gastrointestinal system Gastric emptying amp intestinal transit times
are delayed
Heart burn reflux common
Nausea and vomiting common
Systemic changes in pregnancy
For pregnant patient with Hyper-emesis gravidarium ( excessive and uncontrolled vomiting) morning appointments should be avoided
They should be seated in a semi-supine or comfortable position
In case of vomiting the procedure should be stopped immediately amp the patient should be repositioned upright
When vomiting is over rinsing mouth with cold water or mouthwash is recommended
Systemic changes in pregnancy
bull Urinary System uarr GFR amp renal plasma flow by as much as
50 Nocturia ndashto mobilize the dependent
edema which accumulate during the day uarr Frequency from uarr renal flow plus reduced
bladder capacity from uterine growth It is advisable to ask the patient to void the
bladder just prior to starting the dental procedure
Systemic changes in pregnancy
Endocrine Changes uarrEstrogen uarr progesterone uarrhuman
gonadotropin uarr thyroxin steroid and insulin level Estrogen amp progesterone are insulin
antagonists uarr level of these hormones lead to insulin resistance Thus insulin levels are elevated in pregnant in pregnant patient to compensate this resistance
About 45 of women fail to produce sufficient amount of insulin to overcome this antagonist action amp thus develop gestational diabetes
Systemic changes in pregnancy
Hematological changebull uarr red RBC uarrESR darrHbbull uarrWBCbull uarr circulatory catecholamin amp cortisol lead
to leucositosis bull uarr Coagulation factors except factor XI amp
XIII (anticloting factor) bull so pregnancy is a hypercoagulable state amp
uarr risk for thromboembolism
Systemic changes in pregnancy
bull Pregnant women with anti-phospholipid syndrome are at uarr risk for thrombo-embolisim
bull They are placed on subcutaneous low molecular weight heparin (LMWH)
bull These patients must be hospitalized for dental care

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction

bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms

Treatment of Supine HypotensiveSyndrome
bullRoll patient onto her left side
How should the pregnant woman be positionedbull Flat position may
cause hypotension and hypoxia
bull Place a small pillow under right hip - left lateral displacement
bull Head above feet
Systemic changes in pregnancy
Diaphragm rises about 4 cm darr residual volume uarr awareness of a desire to breath is
common-may be interpreted as dyspnea Increased estrogen in blood causes
engorgement of the nasal capillaries and rhnitis in pregnant women
Frequent nosebleeds amp predisposition to upper respiratory infection
Respiratory system
Systemic changes in pregnancy
Gastrointestinal system Gastric emptying amp intestinal transit times
are delayed
Heart burn reflux common
Nausea and vomiting common
Systemic changes in pregnancy
For pregnant patient with Hyper-emesis gravidarium ( excessive and uncontrolled vomiting) morning appointments should be avoided
They should be seated in a semi-supine or comfortable position
In case of vomiting the procedure should be stopped immediately amp the patient should be repositioned upright
When vomiting is over rinsing mouth with cold water or mouthwash is recommended
Systemic changes in pregnancy
bull Urinary System uarr GFR amp renal plasma flow by as much as
50 Nocturia ndashto mobilize the dependent
edema which accumulate during the day uarr Frequency from uarr renal flow plus reduced
bladder capacity from uterine growth It is advisable to ask the patient to void the
bladder just prior to starting the dental procedure
Systemic changes in pregnancy
Endocrine Changes uarrEstrogen uarr progesterone uarrhuman
gonadotropin uarr thyroxin steroid and insulin level Estrogen amp progesterone are insulin
antagonists uarr level of these hormones lead to insulin resistance Thus insulin levels are elevated in pregnant in pregnant patient to compensate this resistance
About 45 of women fail to produce sufficient amount of insulin to overcome this antagonist action amp thus develop gestational diabetes
Systemic changes in pregnancy
Hematological changebull uarr red RBC uarrESR darrHbbull uarrWBCbull uarr circulatory catecholamin amp cortisol lead
to leucositosis bull uarr Coagulation factors except factor XI amp
XIII (anticloting factor) bull so pregnancy is a hypercoagulable state amp
uarr risk for thromboembolism
Systemic changes in pregnancy
bull Pregnant women with anti-phospholipid syndrome are at uarr risk for thrombo-embolisim
bull They are placed on subcutaneous low molecular weight heparin (LMWH)
bull These patients must be hospitalized for dental care

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction

Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms

Systemic changes in pregnancy
Diaphragm rises about 4 cm darr residual volume uarr awareness of a desire to breath is
common-may be interpreted as dyspnea Increased estrogen in blood causes
engorgement of the nasal capillaries and rhnitis in pregnant women
Frequent nosebleeds amp predisposition to upper respiratory infection
Respiratory system
Systemic changes in pregnancy
Gastrointestinal system Gastric emptying amp intestinal transit times
are delayed
Heart burn reflux common
Nausea and vomiting common
Systemic changes in pregnancy
For pregnant patient with Hyper-emesis gravidarium ( excessive and uncontrolled vomiting) morning appointments should be avoided
They should be seated in a semi-supine or comfortable position
In case of vomiting the procedure should be stopped immediately amp the patient should be repositioned upright
When vomiting is over rinsing mouth with cold water or mouthwash is recommended
Systemic changes in pregnancy
bull Urinary System uarr GFR amp renal plasma flow by as much as
50 Nocturia ndashto mobilize the dependent
edema which accumulate during the day uarr Frequency from uarr renal flow plus reduced
bladder capacity from uterine growth It is advisable to ask the patient to void the
bladder just prior to starting the dental procedure
Systemic changes in pregnancy
Endocrine Changes uarrEstrogen uarr progesterone uarrhuman
gonadotropin uarr thyroxin steroid and insulin level Estrogen amp progesterone are insulin
antagonists uarr level of these hormones lead to insulin resistance Thus insulin levels are elevated in pregnant in pregnant patient to compensate this resistance
About 45 of women fail to produce sufficient amount of insulin to overcome this antagonist action amp thus develop gestational diabetes
Systemic changes in pregnancy
Hematological changebull uarr red RBC uarrESR darrHbbull uarrWBCbull uarr circulatory catecholamin amp cortisol lead
to leucositosis bull uarr Coagulation factors except factor XI amp
XIII (anticloting factor) bull so pregnancy is a hypercoagulable state amp
uarr risk for thromboembolism
Systemic changes in pregnancy
bull Pregnant women with anti-phospholipid syndrome are at uarr risk for thrombo-embolisim
bull They are placed on subcutaneous low molecular weight heparin (LMWH)
bull These patients must be hospitalized for dental care

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms

Systemic changes in pregnancy
Diaphragm rises about 4 cm darr residual volume uarr awareness of a desire to breath is
common-may be interpreted as dyspnea Increased estrogen in blood causes
engorgement of the nasal capillaries and rhnitis in pregnant women
Frequent nosebleeds amp predisposition to upper respiratory infection
Respiratory system
Systemic changes in pregnancy
Gastrointestinal system Gastric emptying amp intestinal transit times
are delayed
Heart burn reflux common
Nausea and vomiting common
Systemic changes in pregnancy
For pregnant patient with Hyper-emesis gravidarium ( excessive and uncontrolled vomiting) morning appointments should be avoided
They should be seated in a semi-supine or comfortable position
In case of vomiting the procedure should be stopped immediately amp the patient should be repositioned upright
When vomiting is over rinsing mouth with cold water or mouthwash is recommended
Systemic changes in pregnancy
bull Urinary System uarr GFR amp renal plasma flow by as much as
50 Nocturia ndashto mobilize the dependent
edema which accumulate during the day uarr Frequency from uarr renal flow plus reduced
bladder capacity from uterine growth It is advisable to ask the patient to void the
bladder just prior to starting the dental procedure
Systemic changes in pregnancy
Endocrine Changes uarrEstrogen uarr progesterone uarrhuman
gonadotropin uarr thyroxin steroid and insulin level Estrogen amp progesterone are insulin
antagonists uarr level of these hormones lead to insulin resistance Thus insulin levels are elevated in pregnant in pregnant patient to compensate this resistance
About 45 of women fail to produce sufficient amount of insulin to overcome this antagonist action amp thus develop gestational diabetes
Systemic changes in pregnancy
Hematological changebull uarr red RBC uarrESR darrHbbull uarrWBCbull uarr circulatory catecholamin amp cortisol lead
to leucositosis bull uarr Coagulation factors except factor XI amp
XIII (anticloting factor) bull so pregnancy is a hypercoagulable state amp
uarr risk for thromboembolism
Systemic changes in pregnancy
bull Pregnant women with anti-phospholipid syndrome are at uarr risk for thrombo-embolisim
bull They are placed on subcutaneous low molecular weight heparin (LMWH)
bull These patients must be hospitalized for dental care

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies

Thank you
Systemic changes in pregnancy
Gastrointestinal system Gastric emptying amp intestinal transit times
are delayed
Heart burn reflux common
Nausea and vomiting common
Systemic changes in pregnancy
For pregnant patient with Hyper-emesis gravidarium ( excessive and uncontrolled vomiting) morning appointments should be avoided
They should be seated in a semi-supine or comfortable position
In case of vomiting the procedure should be stopped immediately amp the patient should be repositioned upright
When vomiting is over rinsing mouth with cold water or mouthwash is recommended
Systemic changes in pregnancy
bull Urinary System uarr GFR amp renal plasma flow by as much as
50 Nocturia ndashto mobilize the dependent
edema which accumulate during the day uarr Frequency from uarr renal flow plus reduced
bladder capacity from uterine growth It is advisable to ask the patient to void the
bladder just prior to starting the dental procedure
Systemic changes in pregnancy
Endocrine Changes uarrEstrogen uarr progesterone uarrhuman
gonadotropin uarr thyroxin steroid and insulin level Estrogen amp progesterone are insulin
antagonists uarr level of these hormones lead to insulin resistance Thus insulin levels are elevated in pregnant in pregnant patient to compensate this resistance
About 45 of women fail to produce sufficient amount of insulin to overcome this antagonist action amp thus develop gestational diabetes
Systemic changes in pregnancy
Hematological changebull uarr red RBC uarrESR darrHbbull uarrWBCbull uarr circulatory catecholamin amp cortisol lead
to leucositosis bull uarr Coagulation factors except factor XI amp
XIII (anticloting factor) bull so pregnancy is a hypercoagulable state amp
uarr risk for thromboembolism
Systemic changes in pregnancy
bull Pregnant women with anti-phospholipid syndrome are at uarr risk for thrombo-embolisim
bull They are placed on subcutaneous low molecular weight heparin (LMWH)
bull These patients must be hospitalized for dental care

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms

Systemic changes in pregnancy
For pregnant patient with Hyper-emesis gravidarium ( excessive and uncontrolled vomiting) morning appointments should be avoided
They should be seated in a semi-supine or comfortable position
In case of vomiting the procedure should be stopped immediately amp the patient should be repositioned upright
When vomiting is over rinsing mouth with cold water or mouthwash is recommended
Systemic changes in pregnancy
bull Urinary System uarr GFR amp renal plasma flow by as much as
50 Nocturia ndashto mobilize the dependent
edema which accumulate during the day uarr Frequency from uarr renal flow plus reduced
bladder capacity from uterine growth It is advisable to ask the patient to void the
bladder just prior to starting the dental procedure
Systemic changes in pregnancy
Endocrine Changes uarrEstrogen uarr progesterone uarrhuman
gonadotropin uarr thyroxin steroid and insulin level Estrogen amp progesterone are insulin
antagonists uarr level of these hormones lead to insulin resistance Thus insulin levels are elevated in pregnant in pregnant patient to compensate this resistance
About 45 of women fail to produce sufficient amount of insulin to overcome this antagonist action amp thus develop gestational diabetes
Systemic changes in pregnancy
Hematological changebull uarr red RBC uarrESR darrHbbull uarrWBCbull uarr circulatory catecholamin amp cortisol lead
to leucositosis bull uarr Coagulation factors except factor XI amp
XIII (anticloting factor) bull so pregnancy is a hypercoagulable state amp
uarr risk for thromboembolism
Systemic changes in pregnancy
bull Pregnant women with anti-phospholipid syndrome are at uarr risk for thrombo-embolisim
bull They are placed on subcutaneous low molecular weight heparin (LMWH)
bull These patients must be hospitalized for dental care

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms
FDA drug classification for pregnancy
bull D = There is evidence of human fetal risk but benefits may outweigh risks
FDA drug classification for pregnancy
bull X = Contraindicated

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms
FDA drug classification for pregnancy
bull D = There is evidence of human fetal risk but benefits may outweigh risks
FDA drug classification for pregnancy
bull X = Contraindicated

Systemic changes in pregnancy
Endocrine Changes uarrEstrogen uarr progesterone uarrhuman
gonadotropin uarr thyroxin steroid and insulin level Estrogen amp progesterone are insulin
antagonists uarr level of these hormones lead to insulin resistance Thus insulin levels are elevated in pregnant in pregnant patient to compensate this resistance
About 45 of women fail to produce sufficient amount of insulin to overcome this antagonist action amp thus develop gestational diabetes

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms
FDA drug classification for pregnancy
bull D = There is evidence of human fetal risk but benefits may outweigh risks
FDA drug classification for pregnancy
bull X = Contraindicated
Common Analgesics
bull paracetamol (B)
bull Ibuprofen (BD)
bull Oxycodone (BD)
bull Hydrocodone and codeine (CD)

bull used to treat mild to moderate pain and fevers
bull short term usage is believed to be safe
bull avoid chronic and large doses of paracetamol
1048715
Analgesics - continued
bull Aspirin is nonteratogenic but may cause maternal and fetal hemorrhage
bull large and chronic doses during last trimester may result in premature closure of ductus arteriosus fetal hypertension anemia and low birth weight
bull avoid ibuprofen in 3rd trimester because of possible adverse circulatory effects
bull short term use of codeine seems safebull avoid codeine late in gestation because of
possible fetal respiratory depression and withdrawal symptoms
Analgesics to Use During1st and 2nd Trimester

bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms
FDA drug classification for pregnancy
bull D = There is evidence of human fetal risk but benefits may outweigh risks
FDA drug classification for pregnancy

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations

Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms
FDA drug classification for pregnancy
bull D = There is evidence of human fetal risk but benefits may outweigh risks
FDA drug classification for pregnancy
bull X = Contraindicated
Common Analgesics
bull paracetamol (B)
bull Ibuprofen (BD)
bull Oxycodone (BD)
bull Hydrocodone and codeine (CD)
avoid in third trimester
Analgesics
bull Paracetamol is the analgesic of choice for all stages of gestation
bull used to treat mild to moderate pain and fevers
bull short term usage is believed to be safe
bull avoid chronic and large doses of paracetamol
1048715
Analgesics - continued
bull Aspirin is nonteratogenic but may cause maternal and fetal hemorrhage
bull large and chronic doses during last trimester may result in premature closure of ductus arteriosus fetal hypertension anemia and low birth weight
bull avoid ibuprofen in 3rd trimester because of possible adverse circulatory effects
bull short term use of codeine seems safebull avoid codeine late in gestation because of
possible fetal respiratory depression and withdrawal symptoms
Analgesics to Use During1st and 2nd Trimester
bull Category B (for best)
bull Paracetamol Ibuprofen
bull Naproxen

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms
FDA drug classification for pregnancy
bull D = There is evidence of human fetal risk but benefits may outweigh risks
FDA drug classification for pregnancy
bull X = Contraindicated
Common Analgesics
bull paracetamol (B)
bull Ibuprofen (BD)
bull Oxycodone (BD)
bull Hydrocodone and codeine (CD)
avoid in third trimester
Analgesics
bull Paracetamol is the analgesic of choice for all stages of gestation
bull used to treat mild to moderate pain and fevers
bull short term usage is believed to be safe
bull avoid chronic and large doses of paracetamol
1048715
Analgesics - continued
bull Aspirin is nonteratogenic but may cause maternal and fetal hemorrhage
bull large and chronic doses during last trimester may result in premature closure of ductus arteriosus fetal hypertension anemia and low birth weight
bull avoid ibuprofen in 3rd trimester because of possible adverse circulatory effects
bull short term use of codeine seems safebull avoid codeine late in gestation because of
possible fetal respiratory depression and withdrawal symptoms
Analgesics to Use During1st and 2nd Trimester
bull Category B (for best)
bull Paracetamol Ibuprofen

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms
FDA drug classification for pregnancy
bull D = There is evidence of human fetal risk but benefits may outweigh risks
FDA drug classification for pregnancy
bull X = Contraindicated
Common Analgesics
bull paracetamol (B)
bull Ibuprofen (BD)
bull Oxycodone (BD)
bull Hydrocodone and codeine (CD)
avoid in third trimester
Analgesics
bull Paracetamol is the analgesic of choice for all stages of gestation
bull used to treat mild to moderate pain and fevers
bull short term usage is believed to be safe
bull avoid chronic and large doses of paracetamol
1048715
Analgesics - continued
bull Aspirin is nonteratogenic but may cause maternal and fetal hemorrhage
bull large and chronic doses during last trimester may result in premature closure of ductus arteriosus fetal hypertension anemia and low birth weight
bull avoid ibuprofen in 3rd trimester because of possible adverse circulatory effects
bull short term use of codeine seems safebull avoid codeine late in gestation because of
possible fetal respiratory depression and withdrawal symptoms
Analgesics to Use During1st and 2nd Trimester

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms
FDA drug classification for pregnancy
bull D = There is evidence of human fetal risk but benefits may outweigh risks
FDA drug classification for pregnancy
bull X = Contraindicated
Common Analgesics
bull paracetamol (B)
bull Ibuprofen (BD)
bull Oxycodone (BD)
bull Hydrocodone and codeine (CD)
avoid in third trimester
Analgesics
bull Paracetamol is the analgesic of choice for all stages of gestation
bull used to treat mild to moderate pain and fevers
bull short term usage is believed to be safe
bull avoid chronic and large doses of paracetamol
1048715
Analgesics - continued
bull Aspirin is nonteratogenic but may cause maternal and fetal hemorrhage
bull large and chronic doses during last trimester may result in premature closure of ductus arteriosus fetal hypertension anemia and low birth weight
bull avoid ibuprofen in 3rd trimester because of possible adverse circulatory effects
bull short term use of codeine seems safebull avoid codeine late in gestation because of
possible fetal respiratory depression and withdrawal symptoms
Analgesics to Use During1st and 2nd Trimester

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms
FDA drug classification for pregnancy
bull D = There is evidence of human fetal risk but benefits may outweigh risks
FDA drug classification for pregnancy
bull X = Contraindicated
Common Analgesics
bull paracetamol (B)
bull Ibuprofen (BD)
bull Oxycodone (BD)
bull Hydrocodone and codeine (CD)
avoid in third trimester
Analgesics
bull Paracetamol is the analgesic of choice for all stages of gestation
bull used to treat mild to moderate pain and fevers
bull short term usage is believed to be safe
bull avoid chronic and large doses of paracetamol
1048715
Analgesics - continued
bull Aspirin is nonteratogenic but may cause maternal and fetal hemorrhage
bull large and chronic doses during last trimester may result in premature closure of ductus arteriosus fetal hypertension anemia and low birth weight
bull avoid ibuprofen in 3rd trimester because of possible adverse circulatory effects
bull short term use of codeine seems safebull avoid codeine late in gestation because of
possible fetal respiratory depression and withdrawal symptoms
Analgesics to Use During1st and 2nd Trimester

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms
FDA drug classification for pregnancy
bull D = There is evidence of human fetal risk but benefits may outweigh risks
FDA drug classification for pregnancy
bull X = Contraindicated
Common Analgesics
bull paracetamol (B)
bull Ibuprofen (BD)
bull Oxycodone (BD)
bull Hydrocodone and codeine (CD)
avoid in third trimester
Analgesics
bull Paracetamol is the analgesic of choice for all stages of gestation
bull used to treat mild to moderate pain and fevers
bull short term usage is believed to be safe
bull avoid chronic and large doses of paracetamol
1048715
Analgesics - continued
bull Aspirin is nonteratogenic but may cause maternal and fetal hemorrhage
bull large and chronic doses during last trimester may result in premature closure of ductus arteriosus fetal hypertension anemia and low birth weight
bull avoid ibuprofen in 3rd trimester because of possible adverse circulatory effects
bull short term use of codeine seems safebull avoid codeine late in gestation because of
possible fetal respiratory depression and withdrawal symptoms
Analgesics to Use During1st and 2nd Trimester
bull Category B (for best)
bull Paracetamol Ibuprofen

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms
FDA drug classification for pregnancy
bull D = There is evidence of human fetal risk but benefits may outweigh risks
FDA drug classification for pregnancy
bull X = Contraindicated

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace

Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms
FDA drug classification for pregnancy
bull D = There is evidence of human fetal risk but benefits may outweigh risks
FDA drug classification for pregnancy
bull X = Contraindicated
Common Analgesics
bull paracetamol (B)
bull Ibuprofen (BD)
bull Oxycodone (BD)
bull Hydrocodone and codeine (CD)
avoid in third trimester
Analgesics
bull Paracetamol is the analgesic of choice for all stages of gestation
bull used to treat mild to moderate pain and fevers
bull short term usage is believed to be safe
bull avoid chronic and large doses of paracetamol
1048715
Analgesics - continued
bull Aspirin is nonteratogenic but may cause maternal and fetal hemorrhage
bull large and chronic doses during last trimester may result in premature closure of ductus arteriosus fetal hypertension anemia and low birth weight
bull avoid ibuprofen in 3rd trimester because of possible adverse circulatory effects
bull short term use of codeine seems safebull avoid codeine late in gestation because of
possible fetal respiratory depression and withdrawal symptoms
Analgesics to Use During1st and 2nd Trimester
bull Category B (for best)
bull Paracetamol Ibuprofen
bull Naproxen
bull Category C (use with caution)
bull Paracetamol with codeine or hydrocodone
bull Paracetamol with oxycodone
Analgesics to Avoid During theThird Trimester

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms
FDA drug classification for pregnancy
bull D = There is evidence of human fetal risk but benefits may outweigh risks
FDA drug classification for pregnancy
bull X = Contraindicated
Common Analgesics
bull paracetamol (B)
bull Ibuprofen (BD)
bull Oxycodone (BD)
bull Hydrocodone and codeine (CD)
avoid in third trimester
Analgesics
bull Paracetamol is the analgesic of choice for all stages of gestation
bull used to treat mild to moderate pain and fevers
bull short term usage is believed to be safe
bull avoid chronic and large doses of paracetamol
1048715
Analgesics - continued
bull Aspirin is nonteratogenic but may cause maternal and fetal hemorrhage
bull large and chronic doses during last trimester may result in premature closure of ductus arteriosus fetal hypertension anemia and low birth weight
bull avoid ibuprofen in 3rd trimester because of possible adverse circulatory effects
bull short term use of codeine seems safebull avoid codeine late in gestation because of
possible fetal respiratory depression and withdrawal symptoms
Analgesics to Use During1st and 2nd Trimester
bull Category B (for best)
bull Paracetamol Ibuprofen
bull Naproxen
bull Category C (use with caution)
bull Paracetamol with codeine or hydrocodone

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms
FDA drug classification for pregnancy
bull D = There is evidence of human fetal risk but benefits may outweigh risks
FDA drug classification for pregnancy
bull X = Contraindicated
Common Analgesics
bull paracetamol (B)
bull Ibuprofen (BD)
bull Oxycodone (BD)
bull Hydrocodone and codeine (CD)
avoid in third trimester
Analgesics
bull Paracetamol is the analgesic of choice for all stages of gestation
bull used to treat mild to moderate pain and fevers
bull short term usage is believed to be safe
bull avoid chronic and large doses of paracetamol
1048715
Analgesics - continued
bull Aspirin is nonteratogenic but may cause maternal and fetal hemorrhage
bull large and chronic doses during last trimester may result in premature closure of ductus arteriosus fetal hypertension anemia and low birth weight
bull avoid ibuprofen in 3rd trimester because of possible adverse circulatory effects
bull short term use of codeine seems safebull avoid codeine late in gestation because of
possible fetal respiratory depression and withdrawal symptoms
Analgesics to Use During1st and 2nd Trimester
bull Category B (for best)
bull Paracetamol Ibuprofen
bull Naproxen
bull Category C (use with caution)
bull Paracetamol with codeine or hydrocodone

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms
FDA drug classification for pregnancy
bull D = There is evidence of human fetal risk but benefits may outweigh risks
FDA drug classification for pregnancy
bull X = Contraindicated
Common Analgesics
bull paracetamol (B)
bull Ibuprofen (BD)
bull Oxycodone (BD)
bull Hydrocodone and codeine (CD)
avoid in third trimester
Analgesics
bull Paracetamol is the analgesic of choice for all stages of gestation
bull used to treat mild to moderate pain and fevers
bull short term usage is believed to be safe
bull avoid chronic and large doses of paracetamol
1048715
Analgesics - continued
bull Aspirin is nonteratogenic but may cause maternal and fetal hemorrhage
bull large and chronic doses during last trimester may result in premature closure of ductus arteriosus fetal hypertension anemia and low birth weight
bull avoid ibuprofen in 3rd trimester because of possible adverse circulatory effects
bull short term use of codeine seems safebull avoid codeine late in gestation because of
possible fetal respiratory depression and withdrawal symptoms
Analgesics to Use During1st and 2nd Trimester
bull Category B (for best)
bull Paracetamol Ibuprofen
bull Naproxen
bull Category C (use with caution)

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms
FDA drug classification for pregnancy
bull D = There is evidence of human fetal risk but benefits may outweigh risks
FDA drug classification for pregnancy
bull X = Contraindicated
Common Analgesics
bull paracetamol (B)
bull Ibuprofen (BD)
bull Oxycodone (BD)
bull Hydrocodone and codeine (CD)
avoid in third trimester
Analgesics
bull Paracetamol is the analgesic of choice for all stages of gestation
bull used to treat mild to moderate pain and fevers
bull short term usage is believed to be safe
bull avoid chronic and large doses of paracetamol
1048715
Analgesics - continued
bull Aspirin is nonteratogenic but may cause maternal and fetal hemorrhage
bull large and chronic doses during last trimester may result in premature closure of ductus arteriosus fetal hypertension anemia and low birth weight
bull avoid ibuprofen in 3rd trimester because of possible adverse circulatory effects
bull short term use of codeine seems safebull avoid codeine late in gestation because of
possible fetal respiratory depression and withdrawal symptoms
Analgesics to Use During1st and 2nd Trimester
bull Category B (for best)
bull Paracetamol Ibuprofen
bull Naproxen
bull Category C (use with caution)
bull Paracetamol with codeine or hydrocodone
bull Paracetamol with oxycodone
Analgesics to Avoid During theThird Trimester

depression and opioid withdrawalbull Codeine (C3D)bull Hydrocodone (C3D)bull Oxycodone(C3D)
Sedation in Pregnancy
bull SedativesAnxiolytics (eg Diazepam ) are rated D and can cause oral clefts with prolonged exposure
bull Nitrous oxide should not be used in 1st trimester (If used in 2nd and 3rd do not go below 50 O2)

bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data

Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side

Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms
FDA drug classification for pregnancy
bull D = There is evidence of human fetal risk but benefits may outweigh risks
FDA drug classification for pregnancy
bull X = Contraindicated
Common Analgesics
bull paracetamol (B)
bull Ibuprofen (BD)
bull Oxycodone (BD)
bull Hydrocodone and codeine (CD)
avoid in third trimester
Analgesics
bull Paracetamol is the analgesic of choice for all stages of gestation
bull used to treat mild to moderate pain and fevers
bull short term usage is believed to be safe
bull avoid chronic and large doses of paracetamol
1048715
Analgesics - continued
bull Aspirin is nonteratogenic but may cause maternal and fetal hemorrhage
bull large and chronic doses during last trimester may result in premature closure of ductus arteriosus fetal hypertension anemia and low birth weight
bull avoid ibuprofen in 3rd trimester because of possible adverse circulatory effects
bull short term use of codeine seems safebull avoid codeine late in gestation because of
possible fetal respiratory depression and withdrawal symptoms
Analgesics to Use During1st and 2nd Trimester
bull Category B (for best)
bull Paracetamol Ibuprofen
bull Naproxen
bull Category C (use with caution)
bull Paracetamol with codeine or hydrocodone
bull Paracetamol with oxycodone
Analgesics to Avoid During theThird Trimester
bull Causes delivery problemsbull Aspirin (C 3D)bull Ibuprofen (B3D)bull Naproxen (B3D)bull Causes neonatal respiratory
depression and opioid withdrawalbull Codeine (C3D)bull Hydrocodone (C3D)bull Oxycodone(C3D)
Sedation in Pregnancy
bull SedativesAnxiolytics (eg Diazepam ) are rated D and can cause oral clefts with prolonged exposure
bull Nitrous oxide should not be used in 1st trimester (If used in 2nd and 3rd do not go below 50 O2)

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms
FDA drug classification for pregnancy
bull D = There is evidence of human fetal risk but benefits may outweigh risks
FDA drug classification for pregnancy
bull X = Contraindicated
Common Analgesics
bull paracetamol (B)
bull Ibuprofen (BD)
bull Oxycodone (BD)
bull Hydrocodone and codeine (CD)
avoid in third trimester
Analgesics
bull Paracetamol is the analgesic of choice for all stages of gestation
bull used to treat mild to moderate pain and fevers
bull short term usage is believed to be safe
bull avoid chronic and large doses of paracetamol
1048715
Analgesics - continued
bull Aspirin is nonteratogenic but may cause maternal and fetal hemorrhage
bull large and chronic doses during last trimester may result in premature closure of ductus arteriosus fetal hypertension anemia and low birth weight
bull avoid ibuprofen in 3rd trimester because of possible adverse circulatory effects
bull short term use of codeine seems safebull avoid codeine late in gestation because of
possible fetal respiratory depression and withdrawal symptoms
Analgesics to Use During1st and 2nd Trimester
bull Category B (for best)
bull Paracetamol Ibuprofen
bull Naproxen
bull Category C (use with caution)
bull Paracetamol with codeine or hydrocodone
bull Paracetamol with oxycodone
Analgesics to Avoid During theThird Trimester

depression and opioid withdrawalbull Codeine (C3D)bull Hydrocodone (C3D)bull Oxycodone(C3D)
Sedation in Pregnancy
bull SedativesAnxiolytics (eg Diazepam ) are rated D and can cause oral clefts with prolonged exposure
bull Nitrous oxide should not be used in 1st trimester (If used in 2nd and 3rd do not go below 50 O2)
Common Antibiotics
bull To treat oral abscess or cellulitisndash Penicillin (B) ndash Amoxicillin (B) ndash Cephalexin (B)ndash Erythromycin base (B) (Not estolate as it

ndash Antacid
ndash Plain water
bull Eat some cheese
Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms
FDA drug classification for pregnancy
bull D = There is evidence of human fetal risk but benefits may outweigh risks
FDA drug classification for pregnancy
bull X = Contraindicated
Common Analgesics
bull paracetamol (B)
bull Ibuprofen (BD)
bull Oxycodone (BD)
bull Hydrocodone and codeine (CD)
avoid in third trimester
Analgesics
bull Paracetamol is the analgesic of choice for all stages of gestation
bull used to treat mild to moderate pain and fevers
bull short term usage is believed to be safe
bull avoid chronic and large doses of paracetamol
1048715
Analgesics - continued
bull Aspirin is nonteratogenic but may cause maternal and fetal hemorrhage
bull large and chronic doses during last trimester may result in premature closure of ductus arteriosus fetal hypertension anemia and low birth weight
bull avoid ibuprofen in 3rd trimester because of possible adverse circulatory effects
bull short term use of codeine seems safebull avoid codeine late in gestation because of
possible fetal respiratory depression and withdrawal symptoms
Analgesics to Use During1st and 2nd Trimester
bull Category B (for best)
bull Paracetamol Ibuprofen
bull Naproxen
bull Category C (use with caution)
bull Paracetamol with codeine or hydrocodone
bull Paracetamol with oxycodone
Analgesics to Avoid During theThird Trimester
bull Causes delivery problemsbull Aspirin (C 3D)bull Ibuprofen (B3D)bull Naproxen (B3D)bull Causes neonatal respiratory
depression and opioid withdrawalbull Codeine (C3D)bull Hydrocodone (C3D)bull Oxycodone(C3D)
Sedation in Pregnancy
bull SedativesAnxiolytics (eg Diazepam ) are rated D and can cause oral clefts with prolonged exposure
bull Nitrous oxide should not be used in 1st trimester (If used in 2nd and 3rd do not go below 50 O2)
Common Antibiotics

Oral Diseases Can Effect Pregnancy
bull Preterm low birth weight (LBW) linked to periodontal disease
bull Thorough calculus (tartar) removal in pregnant women with periodontitis may reduce pre-term births
Periodontal Disease and Preterm LaborbullMaternal periodontal disease is associated with increased risk of preterm laborbullAnaerobic oral gram-negative bacteria cause inflammatory responsebullInflammatory response stimulates prostaglandin and cytokine production to stimulate labor
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms
FDA drug classification for pregnancy
bull D = There is evidence of human fetal risk but benefits may outweigh risks
FDA drug classification for pregnancy
bull X = Contraindicated
Common Analgesics
bull paracetamol (B)
bull Ibuprofen (BD)
bull Oxycodone (BD)
bull Hydrocodone and codeine (CD)
avoid in third trimester
Analgesics
bull Paracetamol is the analgesic of choice for all stages of gestation
bull used to treat mild to moderate pain and fevers
bull short term usage is believed to be safe
bull avoid chronic and large doses of paracetamol
1048715
Analgesics - continued
bull Aspirin is nonteratogenic but may cause maternal and fetal hemorrhage
bull large and chronic doses during last trimester may result in premature closure of ductus arteriosus fetal hypertension anemia and low birth weight
bull avoid ibuprofen in 3rd trimester because of possible adverse circulatory effects
bull short term use of codeine seems safebull avoid codeine late in gestation because of
possible fetal respiratory depression and withdrawal symptoms
Analgesics to Use During1st and 2nd Trimester
bull Category B (for best)
bull Paracetamol Ibuprofen
bull Naproxen
bull Category C (use with caution)
bull Paracetamol with codeine or hydrocodone
bull Paracetamol with oxycodone
Analgesics to Avoid During theThird Trimester
bull Causes delivery problemsbull Aspirin (C 3D)bull Ibuprofen (B3D)bull Naproxen (B3D)bull Causes neonatal respiratory
depression and opioid withdrawalbull Codeine (C3D)bull Hydrocodone (C3D)bull Oxycodone(C3D)
Sedation in Pregnancy
bull SedativesAnxiolytics (eg Diazepam ) are rated D and can cause oral clefts with prolonged exposure
bull Nitrous oxide should not be used in 1st trimester (If used in 2nd and 3rd do not go below 50 O2)
Common Antibiotics
bull To treat oral abscess or cellulitisndash Penicillin (B) ndash Amoxicillin (B) ndash Cephalexin (B)ndash Erythromycin base (B) (Not estolate as it
cause cholestatic hepatitis)ndash Clindamycin (B)

Thank you
Periodontal Disease and Low Birth Weight
bull Periodontal disease is associated with low birth weight
bull Evidence is not conclusivebull Biochemical mechanism similar cascade
as in preterm labor leading to placental blood flow restriction and necrosis
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms
FDA drug classification for pregnancy
bull D = There is evidence of human fetal risk but benefits may outweigh risks
FDA drug classification for pregnancy
bull X = Contraindicated
Common Analgesics
bull paracetamol (B)
bull Ibuprofen (BD)
bull Oxycodone (BD)
bull Hydrocodone and codeine (CD)
avoid in third trimester
Analgesics
bull Paracetamol is the analgesic of choice for all stages of gestation
bull used to treat mild to moderate pain and fevers
bull short term usage is believed to be safe
bull avoid chronic and large doses of paracetamol
1048715
Analgesics - continued
bull Aspirin is nonteratogenic but may cause maternal and fetal hemorrhage
bull large and chronic doses during last trimester may result in premature closure of ductus arteriosus fetal hypertension anemia and low birth weight
bull avoid ibuprofen in 3rd trimester because of possible adverse circulatory effects
bull short term use of codeine seems safebull avoid codeine late in gestation because of
possible fetal respiratory depression and withdrawal symptoms
Analgesics to Use During1st and 2nd Trimester
bull Category B (for best)
bull Paracetamol Ibuprofen
bull Naproxen
bull Category C (use with caution)
bull Paracetamol with codeine or hydrocodone
bull Paracetamol with oxycodone
Analgesics to Avoid During theThird Trimester
bull Causes delivery problemsbull Aspirin (C 3D)bull Ibuprofen (B3D)bull Naproxen (B3D)bull Causes neonatal respiratory
depression and opioid withdrawalbull Codeine (C3D)bull Hydrocodone (C3D)bull Oxycodone(C3D)

Thank you
Periodontal Disease and Preeclampsia
bull Emerging data
bull Mechanism unclear
bull Proposed mechanismndash Periodontal infection leads to
inflammatory vascular damage ndash Triggers cell damage in placenta
Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms
FDA drug classification for pregnancy
bull D = There is evidence of human fetal risk but benefits may outweigh risks
FDA drug classification for pregnancy
bull X = Contraindicated
Common Analgesics
bull paracetamol (B)
bull Ibuprofen (BD)
bull Oxycodone (BD)
bull Hydrocodone and codeine (CD)
avoid in third trimester
Analgesics
bull Paracetamol is the analgesic of choice for all stages of gestation
bull used to treat mild to moderate pain and fevers
bull short term usage is believed to be safe
bull avoid chronic and large doses of paracetamol
1048715
Analgesics - continued
bull Aspirin is nonteratogenic but may cause maternal and fetal hemorrhage
bull large and chronic doses during last trimester may result in premature closure of ductus arteriosus fetal hypertension anemia and low birth weight
bull avoid ibuprofen in 3rd trimester because of possible adverse circulatory effects
bull short term use of codeine seems safebull avoid codeine late in gestation because of
possible fetal respiratory depression and withdrawal symptoms
Analgesics to Use During1st and 2nd Trimester
bull Category B (for best)
bull Paracetamol Ibuprofen
bull Naproxen
bull Category C (use with caution)
bull Paracetamol with codeine or hydrocodone
bull Paracetamol with oxycodone
Analgesics to Avoid During theThird Trimester
bull Causes delivery problemsbull Aspirin (C 3D)bull Ibuprofen (B3D)bull Naproxen (B3D)bull Causes neonatal respiratory
depression and opioid withdrawalbull Codeine (C3D)bull Hydrocodone (C3D)bull Oxycodone(C3D)
Sedation in Pregnancy
bull SedativesAnxiolytics (eg Diazepam ) are rated D and can cause oral clefts with prolonged exposure
bull Nitrous oxide should not be used in 1st trimester (If used in 2nd and 3rd do not go below 50 O2)
Common Antibiotics
bull To treat oral abscess or cellulitisndash Penicillin (B) ndash Amoxicillin (B) ndash Cephalexin (B)ndash Erythromycin base (B) (Not estolate as it
cause cholestatic hepatitis)ndash Clindamycin (B)
Antibiotics
bull penicillin V and amoxicillin is preferred drug for mild to moderate infections
bull widely used for many years with no ill effectsbull no studies show penicillin to be teratogenicbull amoxicillin extensively used without harming
the fetusbull Drug classes1048715 B penicillin cephalosporins erythromycin clindamycin Azithromycin D Tetracycline
Antibiotics To Use During Pregnancy
bull Penicillin V
bull Amoxicillin
bull Erythromycin (base form)
bull Cephalexin cephalosporin
bull Clindamycin
bull Metronidazole
Antibiotics to Avoid duringPregnancy
bull Doxycycline
bull Tetracycline
bull Erythromycin (estolate form)
bull Vancomycin
The Problem With Tetracycline

Periodontitis and Pre-eclampsia
bull Periodontal disease may be associated with pre-eclampsia (Boggess 2003)
bull PGE2 IL-1 and TNF-α from gingival crevicular fluid were higher in women with preeclampsia compared with healthy matched pregnant women (Oettinger-Barak 2003)
Dental Considerations
bull timing of treatment for pregnant patients
bull dental radiation exposure
bull use of local anesthetics
bull prescription of common antibiotics and analgesics
bull nitrous oxide gas administration
Treatment Timing
bull First Trimesterndash Spontaneous miscarriages naturally occur
more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side
Timing of Dental Treatment During Pregnancy - From Little and Fallace
First Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Avoid elective treatment urgent care only
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Second Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care
Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms
FDA drug classification for pregnancy
bull D = There is evidence of human fetal risk but benefits may outweigh risks
FDA drug classification for pregnancy
bull X = Contraindicated
Common Analgesics
bull paracetamol (B)
bull Ibuprofen (BD)
bull Oxycodone (BD)
bull Hydrocodone and codeine (CD)
avoid in third trimester
Analgesics
bull Paracetamol is the analgesic of choice for all stages of gestation
bull used to treat mild to moderate pain and fevers
bull short term usage is believed to be safe
bull avoid chronic and large doses of paracetamol
1048715
Analgesics - continued
bull Aspirin is nonteratogenic but may cause maternal and fetal hemorrhage
bull large and chronic doses during last trimester may result in premature closure of ductus arteriosus fetal hypertension anemia and low birth weight
bull avoid ibuprofen in 3rd trimester because of possible adverse circulatory effects
bull short term use of codeine seems safebull avoid codeine late in gestation because of
possible fetal respiratory depression and withdrawal symptoms
Analgesics to Use During1st and 2nd Trimester
bull Category B (for best)
bull Paracetamol Ibuprofen
bull Naproxen
bull Category C (use with caution)
bull Paracetamol with codeine or hydrocodone
bull Paracetamol with oxycodone
Analgesics to Avoid During theThird Trimester
bull Causes delivery problemsbull Aspirin (C 3D)bull Ibuprofen (B3D)bull Naproxen (B3D)bull Causes neonatal respiratory
depression and opioid withdrawalbull Codeine (C3D)bull Hydrocodone (C3D)bull Oxycodone(C3D)
Sedation in Pregnancy
bull SedativesAnxiolytics (eg Diazepam ) are rated D and can cause oral clefts with prolonged exposure
bull Nitrous oxide should not be used in 1st trimester (If used in 2nd and 3rd do not go below 50 O2)
Common Antibiotics
bull To treat oral abscess or cellulitisndash Penicillin (B) ndash Amoxicillin (B) ndash Cephalexin (B)ndash Erythromycin base (B) (Not estolate as it
cause cholestatic hepatitis)ndash Clindamycin (B)
Antibiotics
bull penicillin V and amoxicillin is preferred drug for mild to moderate infections
bull widely used for many years with no ill effectsbull no studies show penicillin to be teratogenicbull amoxicillin extensively used without harming
the fetusbull Drug classes1048715 B penicillin cephalosporins erythromycin clindamycin Azithromycin D Tetracycline
Antibiotics To Use During Pregnancy
bull Penicillin V
bull Amoxicillin
bull Erythromycin (base form)
bull Cephalexin cephalosporin
bull Clindamycin
bull Metronidazole

more often in 1st trimesterndash Avoid elective treatment that can be delayedndash Offer anticipatory guidance
bull Second Trimesterndash The optimal time for dental treatmentndash Organogenesis complete fetus not largendash Easier to prevent than treat established
diseasebull Third Trimester
ndash Late in term very uncomfortable (short visits)ndash Position slightly on left side

bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms

FDA drug classification for pregnancy
bull X = Contraindicated
Common Analgesics
bull paracetamol (B)
bull Ibuprofen (BD)
bull Oxycodone (BD)
bull Hydrocodone and codeine (CD)
avoid in third trimester
Analgesics
bull Paracetamol is the analgesic of choice for all stages of gestation
bull used to treat mild to moderate pain and fevers
bull short term usage is believed to be safe
bull avoid chronic and large doses of paracetamol
1048715
Analgesics - continued
bull Aspirin is nonteratogenic but may cause maternal and fetal hemorrhage
bull large and chronic doses during last trimester may result in premature closure of ductus arteriosus fetal hypertension anemia and low birth weight
bull avoid ibuprofen in 3rd trimester because of possible adverse circulatory effects
bull short term use of codeine seems safebull avoid codeine late in gestation because of
possible fetal respiratory depression and withdrawal symptoms
Analgesics to Use During1st and 2nd Trimester
bull Category B (for best)
bull Paracetamol Ibuprofen
bull Naproxen
bull Category C (use with caution)
bull Paracetamol with codeine or hydrocodone

depression and opioid withdrawalbull Codeine (C3D)bull Hydrocodone (C3D)bull Oxycodone(C3D)
Sedation in Pregnancy
bull SedativesAnxiolytics (eg Diazepam ) are rated D and can cause oral clefts with prolonged exposure
bull Nitrous oxide should not be used in 1st trimester (If used in 2nd and 3rd do not go below 50 O2)
Common Antibiotics
bull To treat oral abscess or cellulitisndash Penicillin (B) ndash Amoxicillin (B) ndash Cephalexin (B)ndash Erythromycin base (B) (Not estolate as it
cause cholestatic hepatitis)ndash Clindamycin (B)
Antibiotics
bull penicillin V and amoxicillin is preferred drug for mild to moderate infections
bull widely used for many years with no ill effectsbull no studies show penicillin to be teratogenicbull amoxicillin extensively used without harming
the fetusbull Drug classes1048715 B penicillin cephalosporins erythromycin clindamycin Azithromycin D Tetracycline

Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms
FDA drug classification for pregnancy
bull D = There is evidence of human fetal risk but benefits may outweigh risks
FDA drug classification for pregnancy
bull X = Contraindicated
Common Analgesics
bull paracetamol (B)
bull Ibuprofen (BD)
bull Oxycodone (BD)
bull Hydrocodone and codeine (CD)
avoid in third trimester
Analgesics
bull Paracetamol is the analgesic of choice for all stages of gestation
bull used to treat mild to moderate pain and fevers
bull short term usage is believed to be safe
bull avoid chronic and large doses of paracetamol
1048715
Analgesics - continued
bull Aspirin is nonteratogenic but may cause maternal and fetal hemorrhage
bull large and chronic doses during last trimester may result in premature closure of ductus arteriosus fetal hypertension anemia and low birth weight
bull avoid ibuprofen in 3rd trimester because of possible adverse circulatory effects
bull short term use of codeine seems safebull avoid codeine late in gestation because of
possible fetal respiratory depression and withdrawal symptoms
Analgesics to Use During1st and 2nd Trimester
bull Category B (for best)
bull Paracetamol Ibuprofen
bull Naproxen
bull Category C (use with caution)
bull Paracetamol with codeine or hydrocodone
bull Paracetamol with oxycodone
Analgesics to Avoid During theThird Trimester
bull Causes delivery problemsbull Aspirin (C 3D)bull Ibuprofen (B3D)bull Naproxen (B3D)bull Causes neonatal respiratory
depression and opioid withdrawalbull Codeine (C3D)bull Hydrocodone (C3D)bull Oxycodone(C3D)
Sedation in Pregnancy
bull SedativesAnxiolytics (eg Diazepam ) are rated D and can cause oral clefts with prolonged exposure
bull Nitrous oxide should not be used in 1st trimester (If used in 2nd and 3rd do not go below 50 O2)
Common Antibiotics

Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms
FDA drug classification for pregnancy
bull D = There is evidence of human fetal risk but benefits may outweigh risks
FDA drug classification for pregnancy
bull X = Contraindicated
Common Analgesics
bull paracetamol (B)
bull Ibuprofen (BD)
bull Oxycodone (BD)
bull Hydrocodone and codeine (CD)
avoid in third trimester
Analgesics
bull Paracetamol is the analgesic of choice for all stages of gestation
bull used to treat mild to moderate pain and fevers
bull short term usage is believed to be safe
bull avoid chronic and large doses of paracetamol
1048715
Analgesics - continued
bull Aspirin is nonteratogenic but may cause maternal and fetal hemorrhage
bull large and chronic doses during last trimester may result in premature closure of ductus arteriosus fetal hypertension anemia and low birth weight
bull avoid ibuprofen in 3rd trimester because of possible adverse circulatory effects
bull short term use of codeine seems safebull avoid codeine late in gestation because of
possible fetal respiratory depression and withdrawal symptoms
Analgesics to Use During1st and 2nd Trimester
bull Category B (for best)
bull Paracetamol Ibuprofen
bull Naproxen
bull Category C (use with caution)
bull Paracetamol with codeine or hydrocodone
bull Paracetamol with oxycodone
Analgesics to Avoid During theThird Trimester
bull Causes delivery problemsbull Aspirin (C 3D)bull Ibuprofen (B3D)bull Naproxen (B3D)bull Causes neonatal respiratory
depression and opioid withdrawalbull Codeine (C3D)bull Hydrocodone (C3D)bull Oxycodone(C3D)
Sedation in Pregnancy
bull SedativesAnxiolytics (eg Diazepam ) are rated D and can cause oral clefts with prolonged exposure
bull Nitrous oxide should not be used in 1st trimester (If used in 2nd and 3rd do not go below 50 O2)
Common Antibiotics
bull To treat oral abscess or cellulitisndash Penicillin (B) ndash Amoxicillin (B) ndash Cephalexin (B)ndash Erythromycin base (B) (Not estolate as it
cause cholestatic hepatitis)ndash Clindamycin (B)
Antibiotics
bull penicillin V and amoxicillin is preferred drug for mild to moderate infections
bull widely used for many years with no ill effectsbull no studies show penicillin to be teratogenicbull amoxicillin extensively used without harming
the fetusbull Drug classes1048715 B penicillin cephalosporins erythromycin clindamycin Azithromycin D Tetracycline
Antibiotics To Use During Pregnancy
bull Penicillin V
bull Amoxicillin
bull Erythromycin (base form)
bull Cephalexin cephalosporin
bull Clindamycin
bull Metronidazole

Timing of Dental Treatment During Pregnancy - From Little and Fallace
Third Trimester
bull Plaque control
bull Oral hygiene instruction
bull Scaling polishing curettage
bull Routine dental care (after middle of third trimester elective care should be avoided)
Use of Radiation on Pregnant Patient
bull Dose given and time of gestation are important
bull doses lt 5-10 rads (cGy) not teratogenicbull fetus is most susceptible to radiation
between the 2nd and 6th week of gestationbull single dental x-ray exposes patient to 001
millirads of radiation In relative terms this amount is 40 times less than daily dose acquired from cosmic radiation Therefore diagnostic radiation should not be withheld during pregnancy
Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms
FDA drug classification for pregnancy
bull D = There is evidence of human fetal risk but benefits may outweigh risks
FDA drug classification for pregnancy
bull X = Contraindicated
Common Analgesics
bull paracetamol (B)
bull Ibuprofen (BD)
bull Oxycodone (BD)
bull Hydrocodone and codeine (CD)
avoid in third trimester
Analgesics
bull Paracetamol is the analgesic of choice for all stages of gestation
bull used to treat mild to moderate pain and fevers
bull short term usage is believed to be safe
bull avoid chronic and large doses of paracetamol
1048715
Analgesics - continued
bull Aspirin is nonteratogenic but may cause maternal and fetal hemorrhage
bull large and chronic doses during last trimester may result in premature closure of ductus arteriosus fetal hypertension anemia and low birth weight
bull avoid ibuprofen in 3rd trimester because of possible adverse circulatory effects
bull short term use of codeine seems safebull avoid codeine late in gestation because of
possible fetal respiratory depression and withdrawal symptoms
Analgesics to Use During1st and 2nd Trimester
bull Category B (for best)
bull Paracetamol Ibuprofen
bull Naproxen
bull Category C (use with caution)
bull Paracetamol with codeine or hydrocodone
bull Paracetamol with oxycodone
Analgesics to Avoid During theThird Trimester
bull Causes delivery problemsbull Aspirin (C 3D)bull Ibuprofen (B3D)bull Naproxen (B3D)bull Causes neonatal respiratory
depression and opioid withdrawalbull Codeine (C3D)bull Hydrocodone (C3D)bull Oxycodone(C3D)
Sedation in Pregnancy
bull SedativesAnxiolytics (eg Diazepam ) are rated D and can cause oral clefts with prolonged exposure
bull Nitrous oxide should not be used in 1st trimester (If used in 2nd and 3rd do not go below 50 O2)
Common Antibiotics
bull To treat oral abscess or cellulitisndash Penicillin (B) ndash Amoxicillin (B) ndash Cephalexin (B)ndash Erythromycin base (B) (Not estolate as it
cause cholestatic hepatitis)ndash Clindamycin (B)
Antibiotics
bull penicillin V and amoxicillin is preferred drug for mild to moderate infections
bull widely used for many years with no ill effectsbull no studies show penicillin to be teratogenicbull amoxicillin extensively used without harming
the fetusbull Drug classes1048715 B penicillin cephalosporins erythromycin clindamycin Azithromycin D Tetracycline
Antibiotics To Use During Pregnancy
bull Penicillin V
bull Amoxicillin
bull Erythromycin (base form)
bull Cephalexin cephalosporin
bull Clindamycin
bull Metronidazole
Antibiotics to Avoid duringPregnancy
bull Doxycycline

Radiographs during Pregnancy
bull Take as needed with optimal methods for reducing secondary radiation and exposure time
bull Always use a lead apron
bull Exposure to fetus (with apron use) is 00001 centiGray(rad)
bull Daily cosmic radiation - 0004 centiGray (rad)
Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms
FDA drug classification for pregnancy
bull D = There is evidence of human fetal risk but benefits may outweigh risks

Analgesics - continued
bull Aspirin is nonteratogenic but may cause maternal and fetal hemorrhage
bull large and chronic doses during last trimester may result in premature closure of ductus arteriosus fetal hypertension anemia and low birth weight

Risks of Dental X-Rays
bull X-ray only if necessary (ie root canal therapy trauma)
bull When x-rays are indicated radiation exposure is extremely low
bull Exposure can be limited byndash Lead apron shielding ndash Modern fast film ndash Avoiding retakes
FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy
bull C = Studies in animals with adverse effects and no human studies
OR no animal or human studies but benefits of use may outweigh potential harms
FDA drug classification for pregnancy
bull D = There is evidence of human fetal risk but benefits may outweigh risks
FDA drug classification for pregnancy
bull X = Contraindicated
Common Analgesics
bull paracetamol (B)
bull Ibuprofen (BD)
bull Oxycodone (BD)
bull Hydrocodone and codeine (CD)
avoid in third trimester
Analgesics
bull Paracetamol is the analgesic of choice for all stages of gestation
bull used to treat mild to moderate pain and fevers
bull short term usage is believed to be safe
bull avoid chronic and large doses of paracetamol
1048715
Analgesics - continued
bull Aspirin is nonteratogenic but may cause maternal and fetal hemorrhage
bull large and chronic doses during last trimester may result in premature closure of ductus arteriosus fetal hypertension anemia and low birth weight
bull avoid ibuprofen in 3rd trimester because of possible adverse circulatory effects
bull short term use of codeine seems safebull avoid codeine late in gestation because of
possible fetal respiratory depression and withdrawal symptoms
Analgesics to Use During1st and 2nd Trimester
bull Category B (for best)
bull Paracetamol Ibuprofen
bull Naproxen
bull Category C (use with caution)
bull Paracetamol with codeine or hydrocodone
bull Paracetamol with oxycodone
Analgesics to Avoid During theThird Trimester
bull Causes delivery problemsbull Aspirin (C 3D)bull Ibuprofen (B3D)bull Naproxen (B3D)bull Causes neonatal respiratory
depression and opioid withdrawalbull Codeine (C3D)bull Hydrocodone (C3D)bull Oxycodone(C3D)
Sedation in Pregnancy
bull SedativesAnxiolytics (eg Diazepam ) are rated D and can cause oral clefts with prolonged exposure
bull Nitrous oxide should not be used in 1st trimester (If used in 2nd and 3rd do not go below 50 O2)
Common Antibiotics
bull To treat oral abscess or cellulitisndash Penicillin (B) ndash Amoxicillin (B) ndash Cephalexin (B)ndash Erythromycin base (B) (Not estolate as it
cause cholestatic hepatitis)ndash Clindamycin (B)
Antibiotics
bull penicillin V and amoxicillin is preferred drug for mild to moderate infections
bull widely used for many years with no ill effectsbull no studies show penicillin to be teratogenicbull amoxicillin extensively used without harming
the fetusbull Drug classes1048715 B penicillin cephalosporins erythromycin clindamycin Azithromycin D Tetracycline

Ulcer healing drugs
Antacidsbull Almunium hydroxideMagnesium
hydroxidemdashFDA category B Calcium carbonatemdashFDA category C
SimetheconemdashFDA category C
Use of Nitrous Oxide Gas
bull used over 150 years bull safety is being debatedbull SHORT TERM exposure do not cause
birth defects or spontaneous abortionbull CHRONIC exposure may result in fetal
loss and infertilitybull literature suggests that nitrous oxide
should be avoided until more conclusive research is available

FDA drug classification for pregnancybull Combines risk statements including
congenital anomalies fetal effects perinatal risks and therapeutic risk-benefit ratio
bull Untreated disease or condition may pose more serious risks to both mother and fetus than any theoretical risks from the medication
bull Category A thru D and X
FDA drug classification for pregnancy
bull A = Controlled Studies in women fail to demonstrate a risk to the fetus in the first trimester and the possibility of fetal harm appears remote
FDA drug classification for pregnancy
bull B = Animal studies show no risk
or if risk shown in animals controlled trials in women showed no risk
FDA drug classification for pregnancy

Common Analgesics
bull paracetamol (B)
bull Ibuprofen (BD)
bull Oxycodone (BD)
bull Hydrocodone and codeine (CD)
avoid in third trimester
Analgesics
bull Paracetamol is the analgesic of choice for all stages of gestation
bull used to treat mild to moderate pain and fevers
bull short term usage is believed to be safe
bull avoid chronic and large doses of paracetamol
1048715
Analgesics - continued
bull Aspirin is nonteratogenic but may cause maternal and fetal hemorrhage
bull large and chronic doses during last trimester may result in premature closure of ductus arteriosus fetal hypertension anemia and low birth weight
bull avoid ibuprofen in 3rd trimester because of possible adverse circulatory effects
bull short term use of codeine seems safebull avoid codeine late in gestation because of
possible fetal respiratory depression and withdrawal symptoms
Analgesics to Use During1st and 2nd Trimester
bull Category B (for best)
bull Paracetamol Ibuprofen
bull Naproxen
bull Category C (use with caution)
bull Paracetamol with codeine or hydrocodone
bull Paracetamol with oxycodone
Analgesics to Avoid During theThird Trimester

Common Analgesics
bull paracetamol (B)
bull Ibuprofen (BD)
bull Oxycodone (BD)
bull Hydrocodone and codeine (CD)
avoid in third trimester
Analgesics
bull Paracetamol is the analgesic of choice for all stages of gestation
bull used to treat mild to moderate pain and fevers
bull short term usage is believed to be safe
bull avoid chronic and large doses of paracetamol
1048715
Analgesics - continued
bull Aspirin is nonteratogenic but may cause maternal and fetal hemorrhage
bull large and chronic doses during last trimester may result in premature closure of ductus arteriosus fetal hypertension anemia and low birth weight
bull avoid ibuprofen in 3rd trimester because of possible adverse circulatory effects
bull short term use of codeine seems safebull avoid codeine late in gestation because of
possible fetal respiratory depression and withdrawal symptoms
Analgesics to Use During1st and 2nd Trimester
bull Category B (for best)
bull Paracetamol Ibuprofen
bull Naproxen
bull Category C (use with caution)
bull Paracetamol with codeine or hydrocodone
bull Paracetamol with oxycodone
Analgesics to Avoid During theThird Trimester
bull Causes delivery problemsbull Aspirin (C 3D)bull Ibuprofen (B3D)bull Naproxen (B3D)bull Causes neonatal respiratory
depression and opioid withdrawalbull Codeine (C3D)bull Hydrocodone (C3D)bull Oxycodone(C3D)
Sedation in Pregnancy
bull SedativesAnxiolytics (eg Diazepam ) are rated D and can cause oral clefts with prolonged exposure
bull Nitrous oxide should not be used in 1st trimester (If used in 2nd and 3rd do not go below 50 O2)
Common Antibiotics
bull To treat oral abscess or cellulitisndash Penicillin (B) ndash Amoxicillin (B) ndash Cephalexin (B)ndash Erythromycin base (B) (Not estolate as it
cause cholestatic hepatitis)ndash Clindamycin (B)
Antibiotics
bull penicillin V and amoxicillin is preferred drug for mild to moderate infections
bull widely used for many years with no ill effectsbull no studies show penicillin to be teratogenicbull amoxicillin extensively used without harming
the fetusbull Drug classes1048715 B penicillin cephalosporins erythromycin clindamycin Azithromycin D Tetracycline

Analgesics - continued
bull Aspirin is nonteratogenic but may cause maternal and fetal hemorrhage
bull large and chronic doses during last trimester may result in premature closure of ductus arteriosus fetal hypertension anemia and low birth weight
bull avoid ibuprofen in 3rd trimester because of possible adverse circulatory effects
bull short term use of codeine seems safebull avoid codeine late in gestation because of
possible fetal respiratory depression and withdrawal symptoms
