<unk> , also known as<unk>  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<unk><unk> , 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<unk>  giant cell granuloma. Some researchers believe<unk> s to be related to pyogenic<unk> s and, in some instances, are the result of a pyogenic granuloma which has undergone fibrosis and calcification. The term<unk>  has been criticized as this lesion is not related to the<unk><unk>  of bone and is not a<unk> . This term is used in America, however in Britain, this lesion would be termed a fibrous epulis containing bone.
