Abstract

The peripheral odontogenic fibroma (WHO type) is a relatively rare and characteristically benign and unencapsulated, exophytic gingival mass of fibrous connective. Odontogenic epithelium is found within the gingival mass, but usually appears to playa minor role when compared to the fibrous component. The connective tissue is ranged from markedly cellular to relatively acellular and well collagenized. but the connective tissue in this case report appears less cellular. Peripheral odontogenic fibroma must be differentiated histologically from peripheral ossifying fibroma, Peripheral cemental epithelial odontogenic tumor and Peripheral ameloblastoma. The author reports the following conclusions after clinical and radiological examination, excisional biopsy and reviewing literatures. 1. Peripheral odontogenic fibroma is rare lesion and frequently occurs in interdental papila as a form of fibroblastic connective tissue including odontogenic epithelium within the lesion. 2. Peripheral odontogenic fibroma must be differentially diagnosed with Peripheral ossifying fibroma by including less cellular connective tissue, odontogenic epithelium and dysplastic dentin 3. Treatment consists of surgical excision including removal of alveolar bone which is eroded under the lesion
