[Medication-related osteonecrosis of the jaw : a rare but preventable complication]

Medication-related osteonecrosis of the jaw is a rare but severe complication of antiresorptive or antiangiogenic treatments. Prevention relies on patient education, dental screening prior to therapy, and avoidance of invasive procedures. Diagnosis is based on clinical and radiological criteria, with classification into four stages. Management is multidisciplinary and adapted to disease stage: strict oral hygiene, antibiotics, sequestrectomy, or reconstructive surgery. Regular follow-up and close communication among healthcare providers are key to controlling disease progression and maintaining patients' quality of life.
