Resumo
The aim of this study was to describe malocclusion
prevalence and its association with individual and contextual factors
among Brazilian 12-year-old schoolchildren. This cross-sectional study
included data from an oral health survey carried out in Goiânia, Brazil
(n = 2,075), and data from the files of the local health authority. The
data were collected through oral clinical examinations. The Dental
Aesthetic Index (DAI) was used to assess occlusion. The presence
of malocclusion (DAI > 25) was used as the dependent variable. The
individual independent variables consisted of adolescents’ sex and race
and their mothers’ level of schooling. The clinical variables were caries
experience and presence of adverse periodontal condition (calculus
and/or gingival bleeding). The contextual variables included type
of school and the location of schools in the city’s health districts. The
Rao-Scott test and multilevel logistic regression were performed. The
prevalence of malocclusion was 40.1%. In the final model, significantly
higher rates of malocclusion were found among those who attended
schools located in less affluent health districts and whose mothers had
fewer years of education. Rates were also higher among those presenting
calculus and/or gingival bleeding. Malocclusion demonstrated a high
prevalence rate and the inequalities in its distribution were determined
by individual and contextual factors.
