Medication-related osteonecrosis of the jaw (MON, MRONJ) is progressive death of the jawbone in a person exposed to a medications known to increase the risk of disease, in the absence of a previous radiation treatment. It may lead to surgical complication in the form of impaired wound healing following oral and maxillofacial surgery, periodontal surgery, or endodontic therapy. Particular medications can result in MRONJ, a serious but uncommon side effect in certain individuals. Such medications are frequently used to treat diseases that cause bone resorption such as osteoporosis, or to treat cancer. The main groups of drugs involved are anti-resorptive drugs, and anti-angiogenic drugs. This condition was previously known as bisphosphonate-related osteonecrosis of the jaw because osteonecrosis of the jaws correlating with bisphosphate treatment was frequently encountered, with its first incident occurring in 2003. Denosumab, another antiresorptive drug were also related to this condition. However, newer medications such as anti-angiogenic drugs has been established over the years which were reported to be related to osteonecrosis of the jaw as a side-effect too, hence this condition has been renamed as MRONJ. BON was been nicknamed "bis-phossy jaw" based on its similarity with phossy jaw. There is no known prevention for bisphosphonate-associated osteonecrosis of the jaw. Avoiding the use of bisphosphonates is not a viable preventive strategy on a general-population basis because the medications are beneficial in the treatment and prevention of osteoporosis (including prevention of bony fractures) and treatment of bone cancers. It usually develops after dental treatments involving exposure of bone or trauma, or may arise spontaneously. Patients who develop MRONJ may experience prolonged healing, pain, swelling, infection, exposed bone, after dental procedures, though some patients may have no signs/symptoms.
