Bisphosphonates are potent inhibitors of bone resorption, and are used in the treatment of osteoporosis and other diseases that cause bone mass loss, such as Paget's disease, bone metastases, and multiple myeloma, to prevent pathological fractures. Since 2003, avascular osteonecrosis of the jaw has been associated with the use of bisphosphonates, mainly intravenous. According to the literature, the occurrence of osteonecrosis of the jaw has ranged from 0.8% to 12% of the patients on bisphosphonates, most of them on prolonged use. Physicians and odontologists should be aware of that potential complication in dental treatment.
