Cementifying fibroma is a rare neoplasm of the bone, and it is composed of celluler fibrous connective tissue containing variable quantities of cementum. The clinical appearance is typical of any slow-growing odontogenic tumor. Either jaw may be involved, but there appears to be a marked predilection for the mandible. The tumor is more common in young and middle-aged adults. Furthermore, there is a marked predilection for occurrence in females. We experienced a case of cementifying fibroma in the right upper molar region, and report on it with some comments based on the literature. The patiant was a 55-year-old woman. Clinically, mild and diffuse swellings were observed of the right upper molar region. Radiographic examination revealed diffuse mottled radiopaque lesions in the right maxilla. The tumor was surgically removed. Microscopically, the tumor was composed of delicate interlacing collagen fibers, interpersed with large numbers of cellular elements and cementum-like hard tissues. It was diagnosed as cementifying fibroma. The prognosis is fairly good after surgical treatment and there is no recurrence after 4 years and six months.
