OBJECTIVE: To determine the demographic profile of all histologically diagnosed odontogenic cysts (OC) and nonodontogenic cysts (nOC) over a 51-year period in the Brazilian population. STUDY DESIGN: Case records of patients with OC and nOC from the files of the Oral Pathology Service, School of Dentistry, Federal University of Minas Gerais, Belo Horizonte, Brazil, during the period of 1953-2003 were evaluated. RESULTS: Among 19,064 oral biopsies, 2,905 (15.2%) presented criteria of OC and nOC. Of these, 2,812 specimens (14.7%) were diagnosed as OC and 93 (0.5%) represented nOC. The 3 most frequent OC diagnosed were radicular cyst (61.0%), dentigerous cyst (25.3%), and odontogenic keratocyst (7.2%). The most frequent nOC was the nasopalatine duct cyst (2.2%). CONCLUSION: Our results demonstrate that there is a wide range of OC and nOC, with some cysts having a predilection for age, gender, and localization. We also showed demographic aspects and clinical characteristics of these cysts. These could be used as baseline data to obtain more epidemiologic information about the OC and the nOC especially in the Brazilian population.
