Keywords:
Ameloblastoma, odontogenic tumors, epidemiologyAbstract
The ameloblastoma is a tumor originated from odontogenic epithelium,characterized by local invasion and increased rates of recurrence. Methods: The
17-year retrospective study was based on existing data from the archives of Oral
Pathology Department. Files of patients of January 1992-May 2009 with a definitive
diagnostic of ameloblastoma were assessed. Information regarding gender, race,
presence of symptoms, anatomic location and extent was documented. Results:
Within the 60 patients with ameloblastoma observed, the age peak of tumor
incidence was the third decade of life (28.3 %). Females were more prominent than
males, with a ratio 1.22:1. The majority of lesions were showed in Caucasians
patients (51.7 %). The most prevalent site for tumor occurrence was the mandible
(85 %). Symptomatic patients performed a total of 75 %. The majority of patients
had lesions from 3.5 to 6.0 cm of extension (55 %). Conclusions: The
ameloblastoma is more observed in females, in the third decade of life and in the
mandible. The differences with other studies between gender, age, race, extent,
anatomic location and symptoms can be attributed to geographic variations.
