Abstract :
In head and neck cancers radiotherapy is used for therapeutic reasons but it results in a grave complication of Osteoradionecrosis (ORN) of the jaws, specially of the mandible. The incidence rate of ORN was up to 15% with the older radiation modalities. However, new treatment modalties like 3D conformal therapy and intensity modulated radiotherapy has resulted in lower incedence rate of up to 6% . The dentist needs to be aware of symptoms of ORN as they can be the first person to diagnose ORN. We here, report a case of mandibular ORN with pathlogical fracture, and its management.
