There are three types&colon; fibromatous, ossifying and acanthomatous. Not to be confused with ossifying fibroma. It can be confused with the peripheral ossifying fibroma. In contrast to the peripheral ossifying fibroma, the peripheral odontogenic fibroma is a rare lesion. Almost the entire mandible is formed via intramembranous ossification, with just the condyle ossifying endochondrally. The color of peripheral ossifying fibromas ranges from red to pink, and is frequently ulcerated. A primary ossification center is the first area of a bone to start ossifying. Ossifying fibroid epulis should be excised and examined make a definitive diagnosis. They were described in 1893 by Van Arsdale, who called these lesions "homerus ossifying haematoma". Central ossifying fibromas are more common in the mandible around premolars and molars.
