Objective: this study aimed to establish the epidemiological profile of odontogenic lesions from the Department of Pathology and Forensic Medicine (DPML) of the Faculty of Medicine (FM) of the Federal University of Amazonas (UFAM), analyzing the most prevalent histological cyst types and odontogenic tumors, as well as their clinical features. Material and Methods: one hundred forty eight cases of odontogenic lesions were recovered between 1999 and 2014 from the DPML/FM/ UFAM and were analyzed for sex, age, anatomical site, and histological type. These data were submitted to descriptive analysis. Results: out of 148 patients with odontogenic lesions, slight predilection was observed for males (54%, n = 80), who were aged 20-30 years (34.1%, n = 47), with the mandibular site being the most affected with 59.7% (n = 77) of the cases. The histological type of lesions revealed 68.9% (n = 102) cysts and 31.1% (n = 46) odontogenic tumors. Of the cysts, the most prevalent histological type was the radicular cyst (39.3%, n = 40), and among tumors, the most common type was the ameloblastoma (45.6%, n = 21). Conclusion: odontogenic lesions were prevalent in the posterior region of the mandible in males, aged 20-30 years. Cysts were more prevalent than odontogenic tumors and the pattern of histological distribution of both categories was similar to that found in the literature suggesting the predominance of the periapical cyst and ameloblastoma.
