  • Title: Osteonecrosis of the jaws and bisphosphonate therapy.
    Author: Ruggiero SL, Drew SJ.
    Journal: J Dent Res; 2007 Nov; 86(11):1013-21. PubMed ID: 17959890.
    Abstract:
    Bisphosphonates are a class of agents used to treat osteoporosis and malignant bone metastases. The efficacy of these agents in treating and preventing the significant skeletal complications associated with these conditions has had a major positive impact for patients and is responsible for their widespread use in medicine. Despite these benefits, osteonecrosis of the jaws has recently emerged as a significant complication in a subset of patients receiving these drugs. Based on a growing number of case reports and institutional reviews, bisphosphonate therapy may cause exposed and necrotic bone that is isolated to the jaw. This complication usually presents following simple dento-alveolar surgery, and can cause a significant adverse effect on the quality of life for most patients. The pathogenesis for this complication appears to be related to the profound inhibition of osteoclast function and bone remodeling.
