The aim of the present study was to estimate the prevalence of malocclusion and orthodontic treatment need in adolescents of a public school of Fortaleza and grade it according to the severity, to establish priorities in the orthodontic treatment and to determine which components of malocclusion had higher importance in deterrminating malocclusion. Also, were investigated the association between malocclusion and age, gender, income and scholarship. A total of 419 teenagers, between 14 and 19 years old, selected randomly from a population of students of a public school were enrolled in this project. The criteria of graduation and the assessment of malocclusion components were established by a joint of Fortaleza’s orthodontists. The results show that 95,4% of the subjects had some malocclusion, 60,6% of the total had serious malocclusion with compulsory need of orthodontic treatment, and 34,84% had moderate and relative need of treatment. The components with more prevalence, were the molar relation higher than half cusp (30,3%), crossbite (25,7%) and the canine relation higher than a half cusp (22,2%). There wasn’t association between malocclusion and social demographic variables except the relation between age and cross bite (p<0,05), gender and canine relation higher than half a cusp (p<0,05) and mother’s degree of education and molar relation higher than half a cusp (p<0,05).
