Tooth extraction is reported as the main trigger of bisphosphonate (BP) -related osteonecrosis of the jaw (BRONJ). A method to prevent BRONJ has not been scientifically proven. The American Association of Oral and Maxillofacial Surgeons (AAOMS) differs from the International Task Force on Osteonecrosis of the Jaw with regard to the prevention of BRONJ via prophylactic withdrawal before tooth extraction. We performed a multicenter prospective study regarding the development of BRONJ after tooth extraction in BP-treated patients for the purpose of determining factors associated with the frequency of BRONJ. We extracted teeth from patients with a history of current or prior treatment with BP preparations; teeth were extracted using a common treatment protocol. The presence or absence of BRONJ and adverse events were evaluated. A total of 1,323 cases were targeted for this study; 2,371 teeth were extracted. The overall incidence of BRONJ was 1.74%; in the prophylactic withdrawal group it was 1.73%, whereas in the prophylactic non-withdrawal group it was 1.75%. Factors associated with the onset of BRONJ were sex, preparation adaptation classification, oral hygiene state, site of tooth extraction, and Denosumab usage. From analysis that considered the effect of confounding using the propensity score, prophylactic BP withdrawal did not result in a reduction of BRONJ (onset odds ratio with withdrawal: 1.13, 95%CI 0.36-3.57).

Nedaplatin (NDP), an anticancer platinum complex, is supposed to have stronger action on malignant tumor and less nephrotoxicity than cisplatin. As details of the nephrotoxicity of NDP are not known, we studied the effect of NDP on pig kidney Na+, K+-ATPase activity and human renal proximal tubule epithelial cells (HRPTE cells) . The pig kidney Na+, K+-ATPase activity was inhibited by NDP, and the inhibition depended on the incubation time and the concentration of NDP, and the activity was recovered by sulfides. NDP decreased Na+, K+-ATPase and acid phosphatase activities of HRPTE cells, and the decrease was partially inhibited by addition of 2-mercaptoethanol (2ME) . HRPTE cell death by apoptosis was observed in the presence of NDP, and it was also partially inhibited by 2ME. These results suggest that the inhibition of enzyme activities by NDP may be related to nephrotoxicity, and that some sulfides can recover the activities and may reduce nephrotoxicity.
