(Figure 8) and cemento-ossifying fibroma are very similar to ossifying fibromas, but they have a greater tendency to form cementum-like material that is more ovoid and heavily calcified.
to distinguish cementifying fibromas
from ossifying fibromas and fibrous dysplasias by using immunohistochemical analysis for keratan sulfate and chondroitin-4-sulfate, in which the cementifying fibromas
showed significant immuno-reactivity for keratan sulfate, and ossifying fibromas and fibrous dysplasias showed intensive immunostaining for chondroitin-4-sulfate.
may be clinically and radiographically impossible to separate from ossifying fibromas.
11) The numerous terminologies used for these gingival lesions, such as peripheral odontogenic fibroma, peripheral cementifying fibroma
(12) or calcifying fibroid epulis, (3) indicates that there is a lot of controversy regarding the classification.
The others include periapical cementosseous dysplasis, cementifying fibroma
and gigantiform familial cementoma.
