Infected cementoblastoma

Cementoblastoma is a relatively uncommon, benign odontogenic neoplasm of jaws. Mandible is affected more than the maxilla. The lesions are generally diagnosed on a routine radiograph. The localized expansion of cortical plates is observed. Radiographically, it consists of well-defined radiopacity with a radiolucent band. Here is a case report of a female aged 55 years having swelling in the right mandibular angle with an extraoral draining sinus. A panoramic radiograph shows a dense radiopaque mass along the roots of the third molar surrounded by a radiolucent band. Surgical excision was carried out and a histopathological examination was carried out which was suggestive of cementoblastoma.
