SummaryIntroductionBisphosphonates (BPs) have transformed our ability to treat certain malignancies, osteoporosis and hypercalcaemia. This class of drug is assumed to be well tolerated by most. There are some important caveats to this assumption, however, one of the significances being the risk of osteonecrosis of the jaw (ONJ).Material and methodsThis multi-centre retrospective study examined the role of different BPs on the development of ONJ, its clinical presentation and the efficacy of various treatment modalities, comparing these findings with the available literature.ResultsA total of 78 patients from 17 centres were identified with ONJ. A majority of patients identified with ONJ had used Pamidronate or Zoledronate (93.6%) intravenously. 94.9% of patients had received BP in the course of treatment for malignancies and a majority had also received prior chemotherapy or exogenous steroids. 82.1% of patients had received BP for more than 1 year. The mean time from the introduction of BP to the development of ONJ in 24 patients from our department was 31.8 months.ConclusionsThe most common intraoral manifestation was exposed necrotic jawbone. Tooth extractions and oral surgical intervention appear to place patients on BP therapy at risk of ONJ, especially after intravenous BP treatments. ONJ proved in this study to be remarkably refractory to treatment, with radical resection being the only curative approach. We recommend that all patients receive necessary dental treatment prior to commencing BP therapy.
