[Central odontogenic fibroma of the mandible].

Central odontogenic fibroma of the jaw is not a clearly defined lesion. It is rare, asymptomatic, usually found in the mandible and equally involving both sexes. The characteristic feature of the lesion is a high histomorphologic variability, while clinical, x-ray and histologic behavior of the tumor is not specific. All this contributes to the difficulty in diagnosis. Conservative enucleation of the benign tumor is the treatment of choice. The recurrence is rare, but, those with more epithelial elements are more prone to recur.
