Objective: The aim of the present study was to evaluate the normative need for orthodontic treatment and the perception of such need among students aged 11-14 years. Methods: A cross-sectional study was conducted with a sample of 346 students, randomly selected from public and private schools. The Dental Aesthetic Index (DAI) was used to evaluate the normative need for orthodontic treatment (NNOT). The perceived need for treatment among students was assessed by a previously validated questionnaire. Data was analyzed by Pearson’s Chi-squared test (α = 5%). Results: The prevalence of malocclusion and NNOT was 65.6%. Of the sample, 73.7% felt they needed treatment, 66.2% wanted orthodontic treatment and 62.7% were satisfied with their dental aesthetics. A statistically significant association was observed between NNOT and the perception of the need for treatment among the students (p < 0.001). Conclusion: The present study demonstrated a high prevalence of malocclusion, which was reflected in the high normative need for orthodontic treatment. The opinion of patients regarding their expectations of orthodontic treatment should be valued. The students perceived a need for orthodontic treatment.
