[Early childhood caries: prevalence and risk factors in 4-year-old preschoolers in João Pessoa, Paraíba, Brasil].
The purpose of the present study was to evaluate the prevalence of early childhood caries (ECC), in a cohort of children of low socioeconomic status at 48 months of age in João Pessoa, Paraíba, Brazil, in relation to feeding practices, oral health behaviors, fluoride exposure, and enamel defects. 224 children were clinically examined in the Knee-Knee position at the children's home under natural light. Teeth were dried and cleaned with gauze, and caries (WHO index) and defect (DDE Index) were determined. Questionnaires on children's oral hygiene and dietary history were completed by parents or guardians. The SAS statistical program was used with the Mantel-Haenszel tests. The results showed a prevalence of 10.7% and 33.0% for ECC and SECC, respectively. Of all the children examined, 79.9% had at least one tooth with enamel defects, which was the only statistically significant factor (p < 0.001) for ECC. The association between enamel defects and ECC indicates that alterations in the enamel surface may cause progression of dental caries.
