The dental malocclusions are occlusal alterations or disorders that are subject of important aesthetic, ethnic and cultural conditionings, making it difficult its definition and classification. An early diagnosis and a successful treatment of the malocclusions may have benefits in a short term. This research was made in a sample of 450 students aged 8 and 9 years, 232 in the 8-years-old group, for the 51,6 %, and 218 in the 9-years-old group, representing the 48,4 %. With the purpose of determining the orthodontic treatment necessity, we carried out a cross-sectional, descriptive study, applying the dental esthetic index of the orthodontic treatment necessity, and determining that 32,9 % of the students had a slight malocclusion or normal occlusion, 24, 4 % a defined malocclusion, 16,0 % a serious malocclusion and 26,7 % a very serious malocclusion. We determined the high prevalence of treatment necessity in the studied ages.
