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.
Material 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.
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; 95CI 1.2 to 6.4), dissatisfaction with oral aesthetics due to the alignment of the teeth (OR 2.45; 95CI 1.1 to 5.4) and missing teeth (OR 3.02; 95CI 1.0 to 9.23).
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.
