Fatores associados à cárie dentária em pré-escolares do Recife, Pernambuco, Brasil

To investigate factors associated with dental caries in deciduous dentition, a nested case-control study was conducted in a prevalence survey of preschool children (n = 1,690) aged 18 to 36 months and 5 years of age, treated under the Family Health Program in Recife, Pernambuco State, Brazil, in 2006. Cases were children with dmft > 1 and controls with dmft = 0. The independent variables were analyzed in blocks: demographic, environmental, family structure, health care, and dental services use. OR and 95%CI were estimated. Variables associated with the outcome at p < 0.20 in the univariate analysis were included in a multivariate logistic regression model. The cutoff for remaining in the final model was p < 0.10. Larger households (more members), lack of running supply, time of residence, maternal (or caregivers) schooling, attendance in public preschool, demand for dental services, and sugar intake patterns were associated factors. Variables related to social context were the main predictors of caries, thus highlighting the need for comprehensive measures to address other common childhood health problems.

Effect of a Brazilian regional basic diet on the prevalence of caries in rats

The aim of the present study was to determine the effect of a regional basic diet (RBD) on the prevalence of caries in the molar teeth of rats of both sexes aged 23 days. The animals were divided into six groups of 10 rats each receiving the following diets for 30 and 60 days after weaning: RBD, a cariogenic diet, and a commercial diet. The prevalence and penetration of caries in the molar teeth of the rats was then analyzed. The RBD produced caries in 37.5% of the teeth of animals fed 30 days, and in 83.4% of animals fed 60 days, while the cariogenic diet produced caries in 72.5% and 77.5% of the teeth of animals fed 30 and 60 days, respectively. Rats fed the RBD for 30 days had caries in the enamel in 38% of their teeth, 48% had superficial dentin caries, and 7.5% moderate dentin caries. The effect of the RBD did not differ significantly from that of the cariogenic diet in terms of the presence of caries in rats fed 60 days. The penetration depth of the caries produced by the RBD was the same as that produced by the cariogenic diet. Our results show that the RBD has the same cariogenic potential as the cariogenic diet. Since the RBD is the only option for the low-income population, there should be a study of how to compensate for the cariogenicity of this diet.

Comparação de métodos de regressão multivariada no estudo de determinantes da cárie dentária em crianças

Objectives: to compare the results of hierarchical and conventional multivariate models in the investigation of determining factors for tooth decay in children. Methods: an analysis was conducted of an investigation of children served by the Family Health Strategy in Recife, Pernambuco, carried out 2006. The dependent variable was the prevalence of tooth decay (ceo-d≥1); The independent variables were ordered in blocks: socio-economic, life/family context, dental health care. Variables statistically associated with ceo-d ≥1 in univariate analyses with a level of significance ofp≤0.20 were included in the multivariate models. In the hierarchical mode, the order of inclusion of variables was guided by a multidimensional conceptual model. Associated variables with a level of significance of p ≤ 0.10 were retained in the final model. In the conventional logistic model, the significant variables from the univariate analyses were simultaneously included and adjusted. Variables associated with ceo-d with p ≤ 0.10 were retained. Results: in the conventional model the factors associated with ceo-d≥1 were high household density, low level of education of caregiver; studying at public school, seeking treatment/emergency services, and eating sweets. In the hierarchical model, the occupation of the father and the level of education of the mother were also retained in the final model. Conclusion: hierarchical analysis enabled the identification of distal determining factors, which influence lower level factors and their influence on the outcome, thereby providing a more contextualized discussion of the issue.
