Resumo:
O objetivo foi identificar a severidade da má oclusão e fatores associados em adolescentes brasileiros. Foram analisados dados dos 5.445 adolescentes que participaram do inquérito nacional de saúde bucal (SB Brasil 2010), sendo que destes, 4276 permaneceram no estudo com base nos critérios de inclusão. A variável dependente foi má oclusão severa e muito severa, classificada pelo índice de estética dentária (DAI>30). As variáveis independentes foram: local de moradia, macrorregião, cor da pele auto referida, renda, sexo, escolaridade, acesso a serviço de saúde bucal, presença de cárie não tratada e dentes perdidos por cárie, anteriores e posteriores. Foi realizada analise de regressão logística múltipla hierarquizada considerando o plano amostral complexo de conglomerados. A prevalência de má oclusão severa e muito severa foi de 17,5%. Após ajustes, o grupo preto/pardo (OR1,59 IC95%1,09-2,34), a menor renda familiar (OR0,67 IC95%0,55-0,82), a perda por cárie de dentes anteriores (OR2,32 IC95%1,14-4,76) e posteriores (OR1,45 IC95%1,14-1,84) mostraram associação com o desfecho. Concluiu-se que o grupo pretos/pardos, os que possuem menor a renda familiar e os que têm mais dentes anteriores e posteriores perdidos por carie, apresentam maior a chance de ter má oclusão severa/muito severa.

Abstract:
The aim of this study was to identify the severity of malocclusions and associated factors among Brazilian adolescents. Data from 5,445 adolescents, participants of the Brazilian Oral Health Survey (SBBrasil 2010), were evaluated and 4,276 were included based on the inclusion criteria. The outcome was severe and very severe malocclusion, according to the dental aesthetic index (DAI>30). The independent variables were: place of residence, macro-region, ethnicity, gender, income, education level, access to dental care, caries in anterior and posterior teeth, and anterior and posterior tooth loss due to caries. Logistical regression analysis was carried out, considering the complex sampling cluster design, based on a hierarchical model. Prevalence of severe/very severe malocclusions was 17.5%. After adjustments, black/brown ethnicity (OR=1.59, 95% CI: 1.09-2.34), low income (OR=0.67, 95% CI: 0.55-0-82), anterior (OR=2.32, 95% CI: 1.14-4.76) and posterior tooth loss (OR=1.45, 95% CI: 1.14-1.84) due to caries were associated with the outcome. Therefore, black/brown ethnicity, low income and greater number of teeth lost due to caries in both anterior and posterior areas increased the odds for severe/very severe malocclusion.
