Mandibular Cementifying Fibroma in Relation to a Large Periodontal Bone Defect. Report of a Case

Abstract

A cementifying fibroma associated with a large intraosseous periodontal defect is reported. This tumor was located in the lingual aspect of the first lower left molar. Therapy consisted on flap surgery, tumor excision, and placement of a bone autograft in order to fill the residual bone defect. Six months after the treatment, clinical and radiographic signs of periodontal regeneration were evidenced.

Análisis clínico, radiológico e histológico de los fibromas cemento-osificantes de los maxilares

“…The etiologic factor is not clear, but it has been related with inflammatory processes (periodontitis), exodontias and traumatic backgrounds. 14,15 In the patients examined, periodontal disease appears as In the histological study, a fibrous stroma made up of fusiform cells that are mixed with calcified trabecular and/or spherical foci that resemble, respectively, bone and cementum, is observed. It has a moderate vascularization (with occasional erythrocytic extravasation), mitotic activities or atypias is rare, giant cells (generally located in the center of more aggressive behavior presented a greater amount of cementum in their stroma.…”

“…No tiene un factor etiológico claro, pero se ha relacionado con procesos inflamatorios (periodontitis), exodoncias y antecedentes traumáticos. 14,15 En los pacientes examinados, la enfermedad periodontal aparece como antecedente en tres ocasiones y la exodoncia de un tercer molar en otra. La paciente que fue intervenida años antes de un ameloblastoma, presentaba el FCO en el lado opuesto de la mandíbula, por lo que no lo consideramos un factor predisponerte.…”
