Results: The data obtained indicated that there was no statistically significant difference between the genders. Malocclusion was found in 87.4% of the schoolchildren examined, in agreement with the majority of Brazilian and International studies. Class I malocclusion was the most prevalent (39.7%) among the schoolchildren examined, followed by Class II, with 36% of the cases, and there was higher prevalence of Class II division 1 (22.7%) in comparison with Class II division 2 (13.3%).
