ABSTRACT: Aim The objectives of the present study were to assess predictive factors associated to self-perception regarding the need for orthodontic treatment among 170 impoverished schoolchildren. Materials and methods: A cross-sectional study was conducted in public schools in the city of Belo Horizonte-MG (Brazil). Children's self perception regarding the need for treatment was assessed using the Aesthetic Component of the Index of Orthodontic Treatment Need (IOTN-AC) and a questionnaire addressing biopsychosocial factors. The chi-square test and multiple logistic regression were used in the data analysis. Results: The predictive factors for the self perception of orthodontic treatment need on the part of the impoverished schoolchildren included ridicule from persons close to the children regarding the appearance of the teeth (OR 2.81; 95%CI 1.2 to 6.4), dissatisfaction with oral aesthetics due to the alignment of the teeth (OR 2.45; 95%CI 1.1 to 5.4) and missing teeth (OR 3.02; 95%CI 1.0 to 9.23). Conclusion: The alignment of the teeth, missing teeth and ridicule from others regarding the appearance of the teeth are the factors that most strongly influence self-perception regarding the need for orthodontic treatment among impoverished schoolchildren. KEYWORDS: IOTN index; Orthodontic treatment; Orthodontic treatment need.
