Exam and Basic
Hand Instruments
Dental hand instruments are made of metal alloy or plastic resin. They are named according to their use or shape or named for the designer of the instrument.
Hand instruments may be single- or double-ended.
Advantages of double-ended:
two sizes of the same design in one instrument,
two different working ends in one instrument, or two directions of use in one
instrument (right/left).
There are three parts of a hand instrument:
1.Working end. The design determines the function and may be a beveled cutting edge (chisel),
a point(explorer), a nib (amalgam condenser), a blade (composite instrument) or beaks (pliers).
2.Shank. Portion of the instrument that connects the handle and the working end. The shank may be
straight or angled to provide better access to different areas of the mouth.
3.Handle or shaft. Rounded or hexagonal in different diameters and materials for better fit and grip.
MIRROR, MOUTH FUNCTION: To view tissues of the oral cavity and
reflect light for better visibility
FEATURES: Front surface or plane reflective
surface. Front surface mirrors reflect from the
Magnifying and double-sided also available
CLINICAL APPLICATION: Also used to retract and
protect tongue and cheek
EXPLORER FUNCTION: To examine tooth surfaces for caries, calculus, or defects
using sense of touch (tactile)
FEATURES: Thin, sharp working end comes in different designs
May be single- or double-ended (different design on each side)
CLINICAL APPLICATION: Also used to:
Check fit of margins of restorations
Evaluate root surfaces and
furcation area in periodontal
exam (11/12)
Remove excess material from restoration or preparation
Remove excess cement
COTTON PLIERS COTTON PLIERS
FUNCTION: To place and remove small objects from the oral cavity (i.e., cotton pellets, root canal instruments, wedges)
FEATURES: Serrated or nonserrated beaks, locking or nonlocking handles
Also known as College pliers or dressing pliers
CLINICAL APPLICATION: Also used to retrieve materials from drawers and containers to avoid
cross-contamination
SALIVA EJECTOR TIP
FUNCTION: To remove saliva and maintain dry
field using low-volume evacuation
FEATURES: Disposable plastic
Some designed with attached tongue deflector
ANESTHETIC SYRINGE
FUNCTION: To deliver local anesthesia to
intraoral site
FEATURES: Aspirating and Non-aspirating
CLINICAL APPLICATION: An aspirating syringe has a harpoon on the end of the piston, the nonaspirating syringe does not.
With pressure, the harpoon imbeds in the rubber stopper of the anesthetic cartridge.
As the dentist begins the injection, he/she draws back on the thumb ring, pulling the harpoon and the rubber stopper back and creating a
vacuum. This will draw in (aspirate) fluid from the farthest end of the needle. If
blood comes back into the cartridge, the dentist will reposition the needle to
prevent injecting anesthetic agent into a blood vessel.
LOCAL ANESTHESIA
ACCESSORIES
1. Anesthetic needles:
Two lengths—1 (short) and 1 5/8 (long)
Three gauges (diameter)—25 gauge, 27 gauge,
and 30 gauge
Some manufacturers identify gauge by color-
coding caps
Available with plastic or metal hubs
Advantage of larger needles
1)Less deflection
2)Greater accuracy in injection
3)Less chance for breakage
4)More reliable aspiration
5)No perceptual difference in patient discomfort
2. Anesthetic cartridges:
Glass vial containing anesthetic solution such as lidocaine(Xylocaine), mepivacaine (Carbocaine),
prilocaine (Citanest), and bupivacaine (Marcaine).
Aluminum cap with rubber diaphragm that needle penetrates at one end of cartridge.
Rubber stopper at the other end.
Cartridges are sterile and sealed in “blister packs.”
Color coded and labeled with type of anesthetic solution and amount of vasoconstrictor.
Contents of cartridge
1-local anesthetic drug
2-vasoconstrictor
3-anti oxidant
4-Sodium choride
5-distilled water
One of the most important instruments used in the extraction
procedure is the dental elevator
Elevators come in different designs, shapes and sizes
The three major components of the elevator are the handle, shank,
and blade
Dental Elevators.
The shank of the elevator simply connects the handle to the working end, or blade,
of the elevator.
The blade of the elevator is the working tip of the
The blade has two surfaces: a convex and a concave one.
Types of elevators Straight elevator it is used to luxate the teeth
The blade of the straight elevator has a concave surface on one side
Come in different sizes
Cryer’s elevator –
they come in pairs
The triangle shaped elevator is most useful when a broken root
remains in the tooth socket and the adjacent socket is empty
( Commonly used in the mandibular arch)
In experts hands they can be used in the maxilla to luxate maxillary teeth or roots
Winter’s cross-bar elevator
Coupland Chisel
Used to elevate and loosen the tooth from the periodontal
ligament.
Elevation is done to create space and prevent trauma to
adjacent teeth and tissues.
Available in sizes 1, 2 and 3 – working end gets larger with
increase in size number.
Warwick-James elevator – this is a delicate elevator
Available as straight and curved (paired)
It is used to luxate the teeth in the maxilla
Since the handle is flat , the amount of the force aginat the bone will decrease ( reduce the incidence of the fracture)
Crane pick elevator Crane pick elevator is a heavy instrument used to elevate the whole
roots or even teeth
This elevator possess a sharp and thick , curved working that can be
used for removing root
Root tip pick, or apexo elevator– this is a delicate
instrument
The instrument is wedged between the root and the bone
It is not used to push the roots
Double-angled elevators (also refered as Apexo elevator)
They are mainly used to remove root tips in both jaws
Their handle is similar to that of the straight elevator.
The shank has a double angle
The blade has a sharp point which can easily remove small broken root tips
Dental Forceps
Function
Removal of tooth from alveolar bone
Designed in various styles and configurations to adapt to variety of teeth for
which they are used
Components
Components of a dental extraction forceps consists of:
- handle
- Hinge
- beaks
1. Handle
They are made of adequate size
They are serrated
For the maxillary teeth, the forceps are held with palm under the
forceps
For the mandibular teeth, the palm is kept on top of the forceps
Handles can be straight or curved
This provides the operator with a sense of "better fit"
2. Hinge
Like the shank of an elevator
The hinge transfers and concentrates the forces applied
to the beaks.
The American type of forceps has a hinge that is directed in a
horizontal direction with the handles of the forcep
While The English type of forceps has a hinge that is directed
vertically to the handles of the forecep
3. Beaks
The beaks of the forcep are concave on their inner aspect and shaped to fit around the root of the tooth
The beak is designed to adapt to the tooth root at the junction of the crown and root
Individual ForcepsUpper anterior forceps
Used for extracting upper incisors & canines
Beaks are symmetrical & are placed in the same line as the handles
beaks are concave and not pointed
Beaks are shorter than the handles, so that load arm is shorter than
the working arm
Maxillary premolar forceps Used for removing premolars teeth
Beaks are symmetrical , concave, not pointed
The forceps have a slightly curved shape and look like an “S.”
Holding the forceps in the hand, the concave part of the curved handle faces the palm,while the concave part of the beaks is turned upwards
Maxillary molar forceps
There are two maxillary molar forceps: one for the left and one for the right side
Forceps have a slightly curved shape
The have asymmetrical beaks : sharply pointed buccal beak and rounded palatal beak
Beaks are broader than anterior forceps
Maxillary Third Molar Forceps.
It is the longest forceps, due to the posterior position of the third molar
The beaks are offset from the handle in a bayonet fashion
The beaks of forceps are concave and smooth (without pointed ends)
The forceps can be used for extraction of both the left and right maxillry third molar and maxillary second molar (conical roots)
Maxillary cowhorn forceps.
They are particularly useful for maxillary molars whose crowns are severely decayed.
The sharply pointed beaks may reach deeper into the trifurcation
The major disadvantage is that they crush alveolar bone, and when used on intact
teeth without due caution, fracture of large amounts of buccal alveolar bone may
occur.
Maxillary cow horn forceps has a bayonet design, and are commonly used to extract the maxillary third molar , as well as , it can be used to extraxt the maxillary first and secnd molar
Maxillary cow horn forceps have unidentical beaks, one has pointed tip and the other has bifid pointed beaks
With experinced hands, the surgeon can extract the maxillary third molar by engaging the furcation area between the buccal roots by one pointed tip of the bifid beak so that other tips engane the trifurcation area from the distal area and from the palatal sides
Or , as it recommened by the manufacture, the dentist can usually extract the third molar by engaging the single pointed beak on the furcation area between the buccal roots and the other bifid pointed tip engages the palatal root
If Maxillary cow horn forceps is used to extract the maxillary first and second molar, the dentist should engage the single pointed beak on the furcation area between the buccal roots and the other bifid pointed beak should engages the palatal root ( strong apical force is important to engage the cervical portion of the root , not the crown (other wise it will crush the crown)
Upper root forceps
Designed for removing maxillary roots
The handles of the root tip forceps are straight, while the beaks are narrow and offset from the handle in a bayonet fashion
Beaks closely approximate each other and they meat at the ends
Beaks are narrow to fit to the circumference of the root & provide firm grip
Lower anterior forceps
Lower anterior forceps have identical , short closed beaks
Beaks are narrower than lower molar forceps, similar to upper root forceps
Beaks are at right angles to the handles
They can also be used as lower root forceps
Mandibular premolar forcep
The mandibular premolar forcep have identical long and broad open beaks
The mandibular premolar forcep and can be use to extract the mandibular
canine
Lower molar forceps
Beaks are at right angles to the handles
Beaks are symmetrically pointed & the sharp pointed tips engage the
bifurcation at the buccal & lingual surfaces
Beaks are more broader & stout
Mandibular Third Molar Forceps.
These have straight handles, while the beaks, are curved at a
right angle compared to the handles.
The beaks are a little longer compared to the previous forceps
Because this tooth varies in the shape and size and because there is usually no root
bifurcation, the ends of the beaks of the forceps are concave without a pointed
design.( most useful for the third molar with have fused conical roots)
Other types of the lower third forcep, have bilateral pointed tips in the center to adapt
into the bifuraction area if it is present between the roots
Lower cowhorns forceps
They have two heavy beaks with a very sharp tips that can fit into the root bifurcation
These forceps are often used when the crown of the tooth is badly broken down.
They often cause the tooth to split in two the roots can be removed separately with elevators
Mandibular Root Tip Forceps.
The handles of the root tip forceps are straight,while the beaks are curved at a right angle.
Their ends are very narrow and meet at the tip when the forceps are closed
HEMOSTATS
FUNCTION: To securely hold small items, clamp blood vessels, and remove
small pieces of tooth
or bone
NEEDLE HOLDERS
FUNCTION: To hold suture needle
FEATURES: Similar to hemostat but with a
concave area on inside of each beak to allow for
curve of suture needle
To avoid needle breakage, place the needle
holder on the needle just beyond the suture
attachment point and at right angles to the curve
of the needle
SUTURE
FUNCTION: To close incision site
“Stitches” hold tissues in place during healing
FEATURES: Suture material attached to sterile stainless steel needle
Different sizes and designs of needles
Suture may be absorbable—plain or chromic gut, polyglycolic acid (PGA,
Vicryl)
or nonabsorbable—silk, polyester, nylon, polypropylene
Sized by diameter of suture material: 3–0 (000), 4–0 (0000), 5–0 (00000) most
common sizes used in dentistry (smaller number larger diameter)
CLINICAL APPLICATION: Nonabsorbable sutures usually removed at 7–10 days
postsurgical visit
Placed with needle holder or hemostat
SCALPEL
FUNCTION: To cut soft tissue—a surgical knife
CLINICAL APPLICATION: For safety, blades are placed and removed from the
metal handle with a hemostat
or a specially designed scalpel blade remover
Used blades should be disposed of in a sharps container
RONGEURS—SIDE-CUTTING and END-
CUTTING To cut and contour bone—removes sharp edges of alveolar crest after
extractions
for better contour of alveolar ridge; removes exostoses
BONE CHISEL AND MALLET
FUNCTION: To remove bone for better contour of alveolar ridge; remove
exostoses, i.e., tori
BONE FILE
FUNCTION: To smooth bone for better contour of alveolar ridge, often following
use of
rongeurs
FEATURES: Straight or curved working ends
Crosscut or straight cutting ridges
Double ended
TISSUE SCISSORS
FUNCTION: To cut and remove excess or diseased soft tissue
Also used to cut sutures after knots are tied during suture placement
