A Case Report on Peripheral Cemento-Ossifying Fibroma

The present report describes a case of peripheral cemento-ossifying fibroma in a 34-year-old male patient. Gingival overgrowth can be considered as peripheral cemento-ossifying fibroma most often affects the gingiva. It is a reactive lesion that grows slowly. It is a benign tumor that enlarges significantly and eventually causes the teeth to migrate pathologically. It usually happens after a gingival irritation or injury. These lesions are said to arise from the PDL fibers, excision of these lesions along with the periosteum is very important to avoid recurrence. The recurrence rate of peripheral cemento-ossifying fibroma has been reported to be 8-20%, so a close postoperative follow-up is required. Confusion pertains to diagnose PCOF only on clinical examination, histopathologic confirmation is necessary to arrive at the accurate diagnosis of PCOF. Complete surgical excision of the lesion including the periosteum is mandatory as the recurrence rate is high.
