What is Peripheral ossifying fibroma and explain in detail?
A peripheral ossifying fibroma, also known as ossifying fibrous epulis, is “a gingival nodule which is composed of a cellular fibroblastic connective tissue stroma which is associated with the formation of randomly dispersed foci of mineralised products, which consists of bone, cementum-like tissue, or a dystrophic calcification. The lesion is considered part of an ossifying fibroma, but that is usually considered to be a jaw tumor.  Because of its overwhelming incidence on the gingiva, the condition is associated with two other diseases, though not because they occur together.  Instead, the three are associated with each other because they appear frequently on gingiva: pyogenic granuloma and peripheral giant cell granuloma.  Some researchers believe peripheral ossifying fibromas to be related to pyogenic fibromas and, in some instances, are the result of a pyogenic granuloma which has undergone fibrosis and calcification.
The term peripheral ossifying fibroma has been criticized as this lesion is not related to the ossifying fibroma of bone and is not a fibroma. This term is used in America, however in Britain, this lesion would be termed a fibrous epulis containing bone.

Signs and symptoms
The color of peripheral ossifying fibromas ranges from red to pink, and is frequently ulcerated.  It can be sessile or pedunculated with the size usually being less than 2 cm
