Post biphosphonate mandible osteonecrosis: A case study and literature review

Purpose: Bisphosphonates have proven effective in reducing pain and skeletal events in bone metastases treatment. However, there is a long-term complication called osteonecrosis of the jaw, which has been reported for more than a decade. Despite various professional recommendations, there is no international consensus on the best therapeutic strategy. Prevention is crucial, and a multidisciplinary approach must be tailored to each stage of the condition. Design: We present a case of osteonecrosis of the jaw in a patient with metastatic breast cancer who was receiving 4 mg injectable zoledronic acid. Result: The patient stopped treatment with zoledronic acid and received systemic treatment (analgesics, antibiotics), with the resolution of symptoms. Conclusion: ONJ is a serious condition associated with taking BP that can impact oral health and quality of life. Our study highlights the effectiveness of systematic treatment in managing ONJ with BP-related alterations. Preventative measures, such as regular dental consultations, play a vital role in reducing the risk of ONJ. Multidisciplinary management is essential to addressing the different stages of the condition.
