Resumo O objetivo deste estudo foi avaliar a relação entre a alfabetização em saúde bucal (ASB) entre os cuidadores e a cárie dentária não tratada entre pré-escolares. Um estudo transversal foi realizado envolvendo 415 crianças pré-escolares e seus cuidadores de Curitiba-Brasil. As crianças foram examinadas para cárie dentária e placa dental. O ASB dos cuidadores foi avaliado usando um instrumento traduzido e validado para o idioma português do Brasil, o Brazilian Rapid Estimate of Adult Literacy in Dentistry-30. A prevalência de crianças com cárie não tratada foi de 42,9% (IC 95%: 38,1-47,7%). Um baixo grau de ASB foi encontrado entre 15,7% (IC 95%: 12,2-19,2) de cuidadores. A análise de regressão de Poisson multivariada indicou uma maior prevalência de cárie não tratada entre crianças cujos cuidadores apresentaram baixo ASB (PR = 1,35; IC 95%: 1,01-1,79), aqueles com placa visível (PR = 1,28; IC 95%: 1,01-1,62) e aqueles que nunca ou apenas ocasionalmente tiveram seus dentes escovados por seus cuidadores (PR = 1,48; IC 95%: 1,16-1,91) em comparação com aqueles sem essas condições. Pode-se concluir que uma maior prevalência de cárie dentária não tratada foi encontrada entre os pré-escolares cujos cuidadores tinham um baixo grau de ASB.

Abstract The aim of this study was to evaluate the relationship between oral health literacy (OHL) among caregivers and untreated dental caries among preschoolers. A cross-sectional study was conducted involving 415 preschool children and their caregivers from Curitiba, Brazil. The children were examined for dental caries and dental plaque. The caregivers’ OHL was evaluated using an instrument translated and validated for Brazilian Portuguese: the Brazilian Rapid Estimate of Adult Literacy in Dentistry-30. The prevalence of children with untreated caries was 42.9% (95%CI: 38.1-47.7%). A low degree of OHL was found among 15.7% (95%CI: 12.2-19.2) of caregivers. The multivariable Poisson regression analysis indicated a higher prevalence of untreated caries among children whose caregivers had a low OHL (PR = 1.35; 95% CI: 1.01-1.79), those with visible plaque (PR = 1.28; 95% CI: 1.01-1.62) and those who never or only occasionally had their teeth brushed by their caregivers (PR = 1.48; 95% CI: 1.16-1.91) in comparison to those without these conditions. In conclusion, a higher prevalence of untreated dental caries was found among preschool children whose caregivers had a low degree of OHL.

Abstract Objective: To evaluate the relationship between excess body weight (EBW) and the prevalence of dental caries in preschoolers considering parental control regarding snack consumption. Material and Methods: An observational, population-based, cross-sectional study was conducted at Municipal Child Education Centers in the city of Curitiba, Brazil, involving a representative sample of 686 preschool children aged four to five years and eleven months and their parents/caregivers. Dental caries was analyzed using the dmft index. Weight and height were measured for the determination of the body mass index, which was categorized for each z-score range considering age and sex. Children with overweight or obesity were considered to have EBW. The assessment of nutritional status was performed with the aid of the WHO Anthro and WHO Anthro Plus programs. The data were analyzed using univariate and multivariate Poisson regression analysis with robust variance (α= 0.05). Results: The children with EBW had a lower prevalence rate of caries, but this association lost its significance when adjusted by the other variables included in the multivariate model. In the multivariate regression analysis, household income per capita (PR=0.804; 95%CI: 0.665-0.972), child's age (PR=1.015; 95%CI: 1.001-1.029) and snack limits (PR=0.839; 95%IC: 0.732-0.962) were associated with a greater prevalence rate of dental caries. Conclusion: Excess body weight was not significantly associated with dental caries, whereas a lower parental limit regarding snack consumption by the children was independently associated with a higher prevalence rate of dental caries.
