Ameloblastoma is a benign, locally invasive and recurrent, odontogenic tumor, which accounts for about 11% of odontogenic tumors. These tumors occur more frequently in the mandible. The clinical picture presented is generally characterized by slow growing and asymptomatic facial deformities. Treatment depends on the type, location and size of the tumor, as well as the age of the patient. The aim of this paper is to present a retrospective study of diagnosed cases of ameloblastoma in existing data files of the Department of Oral Pathology Catholic University of Minas Gerais, Brazil. Data was collected from the files of patients with a definitive diagnosis of ameloblastoma during the period January 1978 to February 2012. Method: An analysis was made of the data, including sex, race, patient age, symptoms, radiographic appearance of the tumor, the histopathological diagnosis and anatomic location. Results: Of the 48 patients with ameloblastoma there was an increased incidence in the jaw and the angle (45.8%). It affected both men and women, with a mean age of 36 years, and the large majority were asymptomatic (81.2%). The most frequent histological type was multicystic (66.7%), followed by unicystic (31.2%), and peripheral (2.1%). Most lesions were observed in white people (56.3%) and radiographically, it was more often a multilocular image (60.4%). Conclusion: The data reported in this study of ameloblastomas were similar to other series reported in the medical literature.
