Summary: Objective: This study aimed to assess the prevalence of the orthodontic treatment need in Brazilian adolescents by using the Dental Aesthetic Index (DAI), investigate associations between DAI scores and demographic and socioeconomic variables, and identify the components of the DAI that primarily contribute to the severity of malocclusion.Methods: This cross-sectional study was conducted in the public schools of Balneário Camboriú, Brazil; the study sample comprised 704 adolescents aged 12-13 years without history of orthodontic treatment. Malocclusion was assessed by a trained and calibrated orthodontist using the DAI.Results: Of the schoolchildren, 58.7% had no malocclusion, 24.0% had definite malocclusion, 10.9% had severe malocclusion, and 6.4% had handicapping malocclusion. Approximately 17% of the sample (95% confidence interval: 14.5-20.1) required orthodontic treatment. Anterior maxillary overjet (r=0.627), anteroposterior molar relationship (r=0.590), irregularity in the maxilla (r=0.345), irregularity in the mandible (r=0.332), and crowding in the incisal segments (r=0.305) were the DAI components that primarily contributed to the variations in DAI scores.Conclusion: Almost one-fifth of the sample required orthodontic treatment. Maxillary overjet and molar relationship represent the characteristics that primarily influenced the need for orthodontic treatment in the study population.

A má oclusão foi avaliada por um ortodontista treinado e calibrado usando o DAI.Resultados: Das crianças em idade escolar, 58,7% não tinham má oclusão, 24,0% tinham má oclusão definida, 10,9% tinham má oclusão severa, e 6,4% tinham fragilizando má oclusão. Cerca de 17% da amostra (intervalo de confiança de 95%: 14,5-20,1) necessitaram de tratamento ortodôntico. Overjet maxilar (r=0,627), relação molar antero-posterior (r=0,590), irregularidade na maxila (r=0,345), irregularidade na mandíbula (r=0,332); apinhamento de incisivos (r=0,305) foram os componentes do DAI que contribuíram principalmente para as variações nos escores Dai.Conclusão: Quase um quinto da amostra necessitava de tratamento ortodôntico. Overjet maxilar e relação molar representaram as características que influenciaram principalmente a necessidade de tratamento ortodôntico na população do estudo.EDIPUCRS - Editora Universitária da PUCRS2015-07-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Articleapplication/pdfhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/1773610.15448/1980-6523.2014.4.17736Revista Odonto Ciência; Vol. 29 No. 4 (2014); 101-105Revista Odonto Ciência; v. 29 n. 4 (2014); 101-1051980-65230102-946010.15448/1980-6523.2014.4reponame:Revista odonto ciência (Online)instname:Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)instacron:PUC_RSenghttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/17736/13566Copyright (c) 2015 Revista Odonto Ciência (Journal of Dental Science)info:eu-repo/semantics/openAccessTessarolo, Fabio R.Feldens, Carlos A.Dias, CarolineCloss, Luciane Q.2015-10-21T17:52:46Zoai:ojs.revistaseletronicas.pucrs.br:article/17736Revistahttps://revistaseletronicas.pucrs.br/ojs/index.php/foPRIhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/oai||odontociencia@pucrs.br1980-65230102-9460opendoar:2015-10-21T17:52:46Revista odonto ciência (Online) - Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)false
