Peripheral Cemento- Ossifying Fibroma – A Case Report with Unusual Presentation

Peripheral cemento-ossifying fibroma (PCOF) is a reactive neoplasm and presents itself as a gingival overgrowth. It most commonly arises from the periosteum/periodontal ligament. It comprises 9% of all gingival growths and predominantly affects adolescents and young adults. A number of factors have been implicated in the pathogenesis of PCOF including trauma, local irritation such as calculus, ill fitting dentures or faulty restorations. We report a rare case of PCOF of the maxilla in a 4 year old child with previous history of flap surgery in relation to the unerupted tooth. Clinicians and oral and maxillofacial surgeons must be aware of such lesions occurring in the maxilla and must consider it in the differential diagnosis in the appropriate clinical setting.
