ConclusionOur results show that contact between a dentalroot and a drill, screw, or both causes resorptiveroot damage. After discontinuation of the contact,however, repair begins to occur through the depositionof cellular cementum.
P i d ll d d i iPoggio and colleagues recommended a minimumclearance of 1mm between a miniscrewand a root for both periodontal health and mini -screw stability. Therefore, it can be concluded thatminiscrews with a diameter of 1.5mm or less aresafe for interradicular insertion if the space betweenthe roots is at least 3.5mm.

Oral bisphosphonate use and the prevalence of osteonecrosis of the jaw An institutional inquiry - JADA 2009;1401):61-66.Parish P. Sedghizadeh, DDS, MS, Kyle Stanley, BS, Matthew Caligiuri, BA, Shawn Hofkes, BS, Brad Lowry, BS and Charles F. Shuler, DMD, PhDBackground.
Initial reports of osteonecrosis of the jaw (ONJ) secondary to bisphosphonate (BP) therapy indicated that patients receiving BPs orally were at a negligible risk of developing ONJ compared with patients receiving BPs intravenously. The authors conducted a study to address a preliminary finding that ONJ secondary to oral BP therapy with alendronatesodium in a patient population at the University of Southern California was more common than previously suggested.
Methods. The authors queried an electronic medical record system to determine the number of patients with a history of alendronate use and all patients receiving alendronate who also were receiving treatment for ONJ.
Results. The authors identified 208 patients with a history of alendronate use. They found that nine had active ONJ and were being treated in the school’s clinics. These patients represented one in 23 of the patients receiving alendronate, or approximately 4 percent of the population.
Conclusions. This is the first large institutional study in the United States with respect to the epidemiology of ONJ and oral bisphosphonate use. Further studies along this line will help delineate more clearly the relationship between oral BP use and ONJ.
Clinical Implications. The findings from this study indicated that even short-term oral use of alendronateled to ONJ in a subset of patients after certain dental procedures were performed. These findings have important therapeutic and preventive implications.

Oral Bisphosphonate-Induced Osteonecrosis: Risk Factors, Prediction of Risk Using Serum CTX Testing, Prevention, and TreatmentRobert E. Marx, DDS,* Joseph E. Cillo, Jr, DDS, andJuan J. Ulloa, DDS
Purpose: To assess the risk and time course of oral bisphosphonate-induced osteonecrosis of the jaws.Materials and Methods: Detailed data from 30 consecutive cases were compared with 11 6 cases dueto intravenous aminobisphosphonates.
Results. Results in part noted a higher incidence related to alendronate (Fosamax; Merck, WhitehouseStation, NJ), a 94.7% predilection for the posterior mandible, and a 50% occurrence spontaneously, withthe remaining 50% resulting from an oral surgical procedure, mostly tooth removals. Just over 53% ofpatients were taking their oral bisphosphonate for osteopenia, 33.3% for documented osteoporosis, and13.4% for steroid-induced osteoporosis related to 4 or more years of prednisone therapy for anautoimmune condition. There was a direct exponential relationship between the size of the exposedb d th d ti f l bi h h t Th l di t l ti b t tbone and the duration of oral bisphosphonate use. There was also a direct correlation between reportsof pain and clinical evidence of infection. The morning fasting serum C-terminal telopeptide (CTX) testresults were observed to correlate to the duration of oral bisphosphonate use and could indicate arecovery of bone remodeling with increased values if the oral bisphosphonate was discontinued. Astratification of relative risk was seen as CTX values less than 100 pg/mL representing high risk, CTXvalues between 100 pg/mL and 150 pg/mL representing moderate risk, and CTX values above 150 pg/mLrepresenting minimal risk. The CTX values were noted to increase between 25.9 pg/mL to 26.4 pg/mLfor each month of a drug holiday indicating a recovery of bone remodeling and a guideline as to whenoral surgical procedures can be accomplished with the least risk. In addition, drug holidays associatedwith C'IX values rising above the 150 pg/mL threshold were observed to correlate to either spontaneousbone healing or a complete healing response after an office-based debridement procedure.Conclusions: Oral bisphosphonate-induced osteonecrosis is a rare but real entity that is less frequent,less severe, more predictable, and more responsive to treatment than intravenous bisphosphonateinducedosteonecrosis. The morning fasting serum C-terminal telopeptide bone suppression marker is auseful tool for the clinician to assess risks and guide treatment decisions.
