BREDA JUNIOR, Marcus Antonio et al. Large Cement-ossifying Fibroma of Mandible: a Case Report. Rev. cir. traumatol. buco-maxilo-fac. [online]. 2012, vol.12, n.3, pp. 35-40. ISSN 1808-5210.

Cement-ossifying fibroma (COF), despite its similarity, on a smaller scale, to a cement-osseous dysplasia, is considered a true neoplasm with growth potential, relapses being of rare occurrence. The lesion is relatively rare, since many presumed cases in the past, are now recognized as focal cement-osseous dysplasia. Its highest prevalence is in the third and fourth decades of life, and it has a marked predilection for females, affecting, in particular, a single locus of the mandible. The purpose of this paper is to report a case of COF in a 19-year-old male patient, in whom the control radiograph revealed a lesion with varying degrees of radiopacity. The clinical examination showed a slight asymmetry in the region of the left mandibular body. Tomography was evaluated and an excisional biopsy subsequently performed. After two years of follow-up satisfactory bone repair and healing of the gum tissue were observed, with an absence of relapses.
