Osteoradionecrosis (ORN) of facial skeleton has been defined as a necrosis or death of the bone of the mandible or maxilla that may occur following radiation therapy for cancer in the oral and perioral region.1 It is known to occur when jaw bones are directly in the field of radiation. The reported incidence ranges lrom 2.6% t0 22% but most commonly considered to be around 10% + 5%. Diagnosis of ORN depends primarily on clinical and radiographic changes in the bone. The signs and symptoms typically include ulceration of the mucosa, loosening of the teeth, exposure of the necrotic bone; and rarely pain is a significant component.2
