RESUMO

The aim of this study was to evaluate the prevalence of dental malocclusion in schoolchildren (n=332) attending public (n=2) or private (n=2) schools. Data collection involved length of breastfeeding, malocclusion, and socioeconomic status. Using a questionnaire, parents were asked to answer questions regarding length of breastfeeding and family income. Children were then assigned to experimental groups according to their socioeconomic status. In the first group, comparing socioeconomic status to malocclusion, 50.87% of the children were observed to be lower class, with a malocclusion percentage of 59.52% (p<0.05), 35.80% of whom were breastfed for 4 months, 22.30% for 6 months, 14.50% for 1year, 15.70% over 1 year and 11.80% never. No statistically significant difference was observed between socioeconomic status and malocclusion (p>0.05); however, significant difference was observed between breastfeeding, exclusive or not, and malocclusion (p<0.05). Analysis concerning different classes of malocclusion (Angle class I, II, II/2, and III) showed that the longer children are breastfed, the lower their chances are to develop class-II malocclusion. No statistically significant difference was observed for breastfeeding and class social length in relation to presence, or not, of malocclusion; however, statistical difference was found between ?exclusive? breastfeeding and malocclusion.
