RFO, Passo Fundo, v. 23, n. 1, p. 31-36, jan./abr. 2018 Objective: this study aimed to assess the use of dental services in a southern Brazilian city by children aged 12-18 months and to verify the relationship between socioeconomic and demographic variables, as well as maternal use of dental services, and presence of dental caries in the children. It also aimed to describe the prevalence of use of dental services by variables of disparity. Subjects and method: this cross-sectional study was performed on the National Children’s Vaccination Day in 12 public health care centers in Pelotas, RS, Brazil. The data on demographic and socioeconomic status (children’s sex, number of children, family income, and maternal education), pattern of maternal use of dental services, and children’s first dental visit were collected using a semi-structured interview answered by the mothers. Clinical examination was performed to assess dental caries in the children. Chi-square and Fisher’s exact tests were performed to analyze the associations and an equiplot graph investigated disparities in the prevalence of the first dental visit of preschoolers. Results: most children had never been to the dentist (93.4%). The bivariate analysis showed that children who had never been to the dentist belonged to families with lower income, and their mothers presented low level of education and did not use dental services. Conclusion: most children aged 12-18 months had never been to the dentist and there is a socioeconomic disparity in the use of dental services by preschool children.
