Clinicopathological Presentation of Peripheral Ossifying Fibroma with Surgical Management

Peripheral ossifying fibroma (POF) is a slow growing asymptomatic benign tumor which may induce facial asymmetry. It is an occasional growth of the anterior region of mandible and accounts for 3.1% of all oral tumors and 9.6% of the gingival lesions. About 60% of these tumors occur in maxilla and more than 50% of all cases of maxillary POFs are found in the incisors and canine areas. They are thought to arise from the gingival corium, periosteum or periodontal ligament. Dental calculus, plaque, microorganisms, dental appliances, and restorations are considered to be the irritants triggering the lesion. They can cause separation of the adjacent teeth, resorption of the alveolar crest, esthetic deformity. The treatment of choice is complete surgical excision with the removal of the irritating factors. Care must be taken to preserve or reestablish acceptable gingival architecture and periodontal integrity. Here, we present two cases of peripheral ossifying fibroma in left anterior mandible with complete surgical management.
