Eight cases of cementifying fibromas of the Jaws

摘要

Several attempts have been made to classify the cementum-producing tumors, the latest being that proposed by a WHO group (1970) which is used here. The cementifying fibroma is one of these. The lesion is proliferative of fibrous tissue associated with cemental calcification that occurs central or peripheral to the jaw bones. The purpose of the present study is to establish the clinical-roentgenographic analysis of features of this intra-osseous tumor based upon 8 cases that we observed during 1968 to 1986 at Osaka Dental University Hospital.1.The age of the patients were distributed between 13 and 71 years with the average being 42.1.2.All of tumors occured in the mandible, in 5 patients in the premolar-molar region and in 3 patients in the middle mandibular region.3.The tumor has no characteristic roentgenographic features, but the roentgenographic appearance can be classifyied into 3 types, cystic, foggy, and mottled.4.The features of aggressive ossifying-cementifying fibroma are aggresive and locally invasive growth, but there were no patients in this study showing such roentgenographic findings.
