Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a challenging complication of long-term bisphosphonate treatment. Currently, the drawback in the surgical management of BRONJ is the difficulty distinguishing between viable and necrotic bone. Intraoperative bone fluorescence induced by tetracyclines has been shown to be a valuable aid to overcome this problem. In this technical note we report the finding that viable bone is auto-fluorescent using the VELscope Vx fluorescence lamp. Necrotic bone shows an altered fluorescence pattern (pale or no fluorescence). Thus it is suggested that auto-fluorescence of bone might be of similar use during the surgical therapy of BRONJ.
