Material and methods 603 preschoolers, enrolled in public preschools in Itajaí (state of Santa Catarina, Brazil), took part in the study. To assess the participants’ socio-economic characteristics, an original questionnaire was formulated and sent to the children’s parents. The clinical evaluation was carried out by a calibrated examiner using the deft/DMFT index for dental caries and Ghanim et al. (Ghanim et al., Eur Arch Paediatr Dent, 2015) criteria for HSPM. The data were analyzed through Poisson regression, using STATA statistical software, and the association analyses were presented by prevalence ratios (PR).
