Cemento-Ossifying Fibroma of Maxilla: An Unusual Case Report

Abstract

Cemento-ossifying fibroma (COF) is a benign fibro-osseous lesion which belongs to the same category of fibrous dysplasia and cement-ossifying dysplasia. It arises from the periodontal membrane which contains multipotent cells that are capable of forming cementum, lamellar bone, and fibrous tissue. It is more common in the mandible than in the maxilla. We present a case of COF in the maxilla, a rare occurrence in a 66-year-old female with the chief complaint of a swelling in the left upper back tooth region for the past 3 years. A panoramic radiograph was taken, which showed an oval radiopaque lesion in the second quadrant from 24 to maxillary tuberosity. In the maxilla, the clinical and radiological differential diagnosis includes fibrous dysplasia, giant cell lesions, cementoblastoma, calcifying epithelial odontogenic tumor, and peripheral giant cell granuloma. It is sharply circumscribed and demarcated from the surrounding bone, so surgical excision is the treatment of choice.

Radiographic appearance of ossifying fibroma in the left mandible: a case report

“…Cases that occur in the mandible, as much as 77% occur in the premolars, while 75 to 89% occur in the molars. 4 Usually cases of OF are diagnosed in the third to fourth decade, with a female predilection. The prevalence is more in the white race.…”

“…So that cementoblastoma can be ruled out from a definite diagnosis and can only be used as a differential diagnosis. 4,7 Appropriate treatment can be carried out if the diagnosis process is carried out properly. OF has the characteristics of well-defined and separated from the bone even though the lesion reaches a very large size, so that complete excision and resection must be carried out.…”
