Peripheral odontogenic fibroma is a benign tumour that arises from the [[Periodontal ligament - Anatomy & Physiology|periodontal ligament]]. It was previously known as a fibromatous epulis and ossifying epulis depending on the degree of mineralization.

They present as firm, smooth swellings of the [[Oral Cavity - Teeth & Gingiva - Anatomy & Physiology|gingiva]] and are normally indistinguishable from [[Gingival Hyperplasia - WikiClinical|gingival hyperplasia]].

===Diagnostic Imaging===

===Diagnostic Imaging===

Radiographs are required to differentiate this benign neoplasm from malignant or locally aggressive lesions. Skull radiographs will evaluate the oral lesion itself and thoracic radiography to evaluate for metastasies (if a malignancy is a diagnostic possibility). Radiographs typically show a soft tissue opacity in the the [[Oral Cavity - Teeth & Gingiva - Anatomy & Physiology|gingiva]] region with varying degrees of mineralization. Bone involvement is '''not''' a feature of this neoplasm.
