OBJECTIVE(S): Bisphosphonates are frequently used worldwide mostly in osteoporosis and skeletal bone metastases. However, a serious side-effect is bisphosphonate related osteonecrosis of the jaws (BRONJ). The mechanism behind BRONJ remains unclear. In literature several origins are suggested. Presence of the teeth in the jaws may play an important role. Therefore in this study 45 patients were analyzed retrospectively. STUDY DESIGN: Files of 45 patients with a diagnosis of BRONJ were analyzed, meaning clinical features, bisphosphonate use, dental history including luxating moment and (previous) treatment. RESULTS: In 97.5% (n = 44) a certain or presumable dental focus, such as extractions, a previous dental treatment or prosthesis complaints were found as initiating factor of BRONJ. CONCLUSION: In contrast to findings in literature, in our group of patients a dental focus was found in 44 of 45 cases. This implies a dentoalveolar start of BRONJ with subsequent spreading into the jaws in nearly all cases.
