The knowledge of the epidemiological characteristics such as anatomic location, age, and gender of the patients with odontogenic tumors is extremely valuable in the development of differential diagnoses. In the present observational and retrospective study, the objective was to check the occurrence of these tumors in patients attended at the project of Oral Lesions: ‘Diagnosis, treatment and epidemiology of diseases of the oral cavity’ of the State University of Maringa, between 1995 and 2015. Data were obtained from the project charts, in what concerns the variables: gender, age, race, diagnosis, lesion site, time of evolution, symptomatology and radiographic characteristics. Tumors were classified in agreement with the World Health Organization (2005). A total of 2581 records were analyzed. Among them 32 (1.45%) showed the diagnosis of odontogenic tumor. There was no statistically significant difference among genres. The age group with greater incidence was 23-33 years old. Among the patients, 55.3% stated they did not know which the time span of evolution of the tumor. There was greater incidence in people of Caucasian origin and the most affected site was the left posterior region of the mandible. The keratocystic odontogenic tumor, followed by ameloblastoma and odontoma were shown to be the most common neoplasms found in the patients who participated in the project.
