Avaliação da presença de maloclusão e fatores associados em pré escolares de Governador Valadares, MG.

Abstract

The aim of the study was to determine the presence of malocclusion and associated factors in 76 children with primary dentition. This is an observational cross sectional study, carried out in preschoolers aged 1 to 6 years, of both sexes, enrolled in the daycare centers Pequeno Cidadão and Olegário Maciel, in the municipality of Governador Valadares, MG. The clinical examination was performed by two previously trained and calibrated examiners. The condition with the highest prevalence was accentuated maxillary overjet (31.7%), followed by open bite (19.0%), posterior crossbite (12.7%) and mandibular overjet (6.3%). Most of the children with a maxillary overjet presented an open bite. Most of the children with maxillary overjet had an open bite. The analysis process was performed using the Stata 12.0 software, and Pearson's, Fisher's or Linear Trend Chi-Square tests, depending on the type of display variable. For multivariate analysis, Poisson regression was performed. The variables with p> 0.20 in the bivariate analysis were not included in the multivariate analysis model, the prevalence ratio (PR) and the 95% confidence intervals were obtained. The variables included in the final model were those with a value of p <0.05. Conclusion: A high prevalence of malocclusion was found in this population, reinforcing the need for interventions to reduce risk factors.
