INTRODUCTION: We describe our experience with oncology patients on a frequent dosing schedule of intravenous (i.v.) bisphosphonates at the Jordan University Hospital (JUH). PATIENTS AND METHODS: Patients treated by i.v. bisphosphonates in the medical oncology unit at the JUH were examined for bisphosphonate-related osteonecrosis of the jaws (BRONJ). Diagnosis was made according to the guidelines of the American Association of Oral and Maxillofacial Surgeons (AAOMS) original position paper. RESULTS: Of the 41 patients, four developed BRONJ, two in maxilla, one in mandible and one bimaxillary. Patients with BRONJ were older; mean age was 69.3 +/- 3.1 years compared to 62.8 +/- 12.5 years (P = 0.022). Dental co-morbidities were more commonly present in patients with the disease (P = 0.038). Patients who developed BRONJ were on treatment for a longer duration of time; the mean duration of treatment was 23.5 +/- 8.4 months compared to 11.9 +/- 13.4 months (P = 0.10). CONCLUSIONS: The results of this case series demonstrated that age and poor oral health status are significant risk factors of BRONJ for oncology patients on long-term frequent dosing schedule of i.v. bisphosphonates.
