Abstract

Objective: The objective of this study was to analyze the frequency and distribution of odontogenic tumors in Fortaleza, Brazil, and compare the findings with those reported in the literature.

Study design: A total of 6231 oral lesions retrieved from 5 anatomic pathology services in Fortaleza, Brazil, over a 5-year period, were reviewed. In addition, the literature was searched for studies on odontogenic tumors (OTs) according to the 2005 WHO classification.

Results: Within the total 6231 oral lesions, 185 (2.97%) were OTs, all benign. OTs presented a female predilection, with a male:female ratio of 0.62:1.00. These neoplasms occurred over a wide range of ages (1 to 78 years), with a mean of 30.5 years. Ameloblastomas, keratocystic odontogenic tumors, and odontomas were the most frequent OT types.

Conclusions: OTs are rare neoplasms and appear to show geographic variations. In Fortaleza, Brazil, they are more common in female patients, with ameloblastoma followed by keratocystic odontogenic tumors as the most frequent OTs.
