Cemento Ossifying Fibroma: A Pathological Entity

Cemento-ossifying fibroma is a controversial term because of its terminology and its diagnosis. Cemento-ossifying fibroma is odontogenic in origin although it is a central neoplasm of bone and involving the periodontium. Most Cemento-ossifying fibromas exhibit slow and expansile growth in the jaws and are benign in origin. The lesion is encapsulated with mixed radiodensties. The Cemento-ossifying fibroma is characterized by replaced of normal bone by fibrous tissue and varying amounts of osteoid and cementum like material. The definitive diagnosis of such lesions require clinical, radiological and histopathological observations. The treatment of choice is surgical resection and recurrence in uncommon. We report a case of Cemento ossifying fibroma in left mandibular premolar region and discuss how to confirm the diagnosis.
