Abstract
OBJETIVO: Avaliar como o desenvolvimento de habitos bucais deleterios e os problemas de fala afetam a oclusao dentaria em pre-escolares. METODOS: Foi constituida a amostra probabilistica por 2.139 criancas de ambos os sexos, na faixa etaria de 3 a 5 anos, matriculadas em instituicoes publicas ou privadas do Municipio de Bauru, SP, Brasil. Foi desenvolvido estudo transversal em duas etapas: exame de oclusao e questionario socioeconomico. A classificacao de Angle foi adotada para avaliacao de aspectos morfologicos da oclusao, observando-se tambem trespasse horizontal e vertical, espacamento/apinhamento, mordida aberta anterior, mordida cruzada total, mordida cruzada anterior e mordida cruzada posterior uni ou bilateral. Uma subamostra de 618 criancas apresentou resposta ao questionario sobre habitos bucais, saude infantil e informacoes sobre condicoes socioeconomicas. RESULTADOS: A prevalencia de ma oclusao foi de 51,3% para o sexo masculino e 56,9% para o sexo feminino, sem variacao quanto ao sexo. A maior prevalencia de ma oclusao foi verificada no grupo etario de tres anos, decrescendo significantemente com a idade (p<0,05). CONCLUSOES: Entre os fatores ambientais estudados, o habito de succao de chupeta foi o mais importante na associacao com ma oclusao (OR=5,46), seguido da succao digital (OR=1,54). Dificuldades na fala nao apresentaram relacao com a ma oclusao.
