Abstract

Osteonecrosis of the jaw (ONJ) is an adverse drug reaction described as the progressive destruction and death of bone that affects the mandible and maxilla of patients exposed to the treatment with medications known to increase the risk of disease, in the absence of a previous radiation treatment. Tooth extraction often precedes the manifestation of ONJ; indeed, it is sometimes called trigger event and it have also been considered as risk factors for the onset of ONJ. As a consequence, some of the guidelines recommend avoiding tooth extractions in patients at risk of ONJ; however, a growing body of evidence indicates that dental/periodontal infection prior to extraction, rather than dental extraction may represent the main local risk factor for ONJ. Ten patients at risk of ONJ have undergone tooth extractions. They were identified and included in our retrospective monocentric clinical investigation. Patients underwent tooth extractions with standardized procedures (PROMaF protocol), and bone biopsies were taken. Extractions were performed due to symptomatic, non-restorable teeth in patient at risk of ONJ; histological findings of ONJ were observed in all samples. This outcome may highlight that the proof of non‐exposed ONJ might be the histopathologic confirmation of necrotic bone, as stated by European task force on MRONJ. Additionally, alveolar biopsy should possibly be taken in every case of suspected ONJ, which needs an proper and prompt management for successful healing
