Odontogenic Calcificant Cystic Tumor (OCCT) is an infrequent injury. It arises from odontogenic epithelial rests present in the maxilla, jaw or gum. Gorlin and col. described the OCCT for first time as an own pathological entity in 1962. Clinically, the OCCT represents 1% of the odontogenic injuries. It is possible to be found from the first decade to the eighth decade. It affects in same proportion the maxilla and the jaw, being the most common in the dented zones, with greater incidence in the first molar area. Two case reports of OCCT in two different ages, both in female individuals, one at 5 years old and the other at 35 years old are presented. Enucleation of the tumor was the treatment chosen. The purpose of this article is to present a review of the literature related to these two cases of OCCT and its treatment, putting an emphasis on its aetiology, biological behaviour and treatment.
