Medication-Related Osteonecrosis of the Jaw – 2024 Update

As the global number of patients with osteoporosis and malignant diseases such as breast cancer, multiple myeloma, and prostate cancer increases every year, there is an associated rise in the use of antiangiogenic medications and antiresorptive medications. With increasing frequencies in the use of antiangiogenic and antiresorptive medications, there is an associated increase in the number of medication-related osteonecrosis of the jaw (MRONJ) cases reported from patients. MRONJ has emerged as a significant comorbidity in cancer patients treated with antiangiogenics or high doses of potent antiresorptive agents, such as bisphosphonates (BPs) or denosumab. MRONJ first emerged from BP-treated cancer patients who presented with a spectrum of dental problems, including delayed wound healing following a dental extraction or oral surgery, exposed bone, soft tissue infection and inflammation, anesthesia, paresthesia, odontalgia, sinus pain, and aching bone pain in the mandible, which continues to be a significant source of problems for dentists, physicians, and patients today. A significant number of MRONJ cases secondary to osteoporosis have also been reported in osteoporotic patients receiving antiresorptive medications. The American Association of Oral and Maxillofacial Surgeons (AAOMS) has established diagnostic standards for MRONJ based on pharmacological history, clinical signs, and radiographic findings. However, as the expertise and knowledge base for MRONJ continues to evolve, revisions and refinements for MRONJ pathogenesis and treatment strategies are necessary to reflect the current research status of the disease correctly. This review highlights current scientific information associated with MRONJ to identify and summarize preventative measures, and treatment interventions for reading the impact of this debiliating disorders.
