Objective:This study aims to evaluate the association between early childhood caries (ECC) and maternal caries status, and the maternal perception of ECC risk factors.Materials and Methods:A cross-sectional study was carried out with 77 mother-child pairs, the children ranging from 12 to 36 months of age and their mothers, who were seeking dental care at a health center in São Luís, Maranhão, Brazil. Data collection was conducted using a specific questionnaire for mothers. Oral clinical examination of the mother-child binomial to assess caries incidence, gingival bleeding (GB) and visible plaque was done. Home visits were performed in 10% of the sample in order to observe the environmental conditions, dietary habits and dental hygiene practices.Results:The findings showed that the caries prevalence in children was 22.5 times higher in the mother who had decayed tooth (prevalence ratio [PR] = 22.5, confidence interval [CI] 95% = 3.2–156.6, P < 0.001). GB also was observed in 14 mothers and children, the PR in pair was 12.2 (CI95% = 1.6–88.9, P < 0.001). The variables are related for the mother-child binomial in regression linear analysis.Conclusion:The maternal caries status was associated with ECC.
In this study, we modeled the pathways in the association of socioeconomic status, frequency of added sugar consumption, and obesity in mother-child dyads with chronic oral disease burden in early childhood using structural equation modeling.A population-based study was conducted on preschoolers from public daycare centers in São Luís, Brazil (n = 674) and their mothers. Chronic oral disease burden in early childhood was a latent variable, representing the shared variance of the following indicators: visible plaque index, gingivitis, and dental caries. A higher consumption frequency of added sugars by children [standardized regression coefficient (SC) = 0.219] explained the chronic oral disease burden. A higher consumption frequency of added sugars by mothers was associated with greater consumption of sugar by children (SC = 0.236), and indirectly with a greater chronic oral disease burden (SC = 0.052). Maternal obesity was associated with obesity in the offspring (SC = 0.130). The chronic oral disease burden is already present in early childhood and can be explained by the higher consumption of added sugars by the mother-child dyad. Approaches to preventing chronic oral diseases should focus on common risk factors, start early in life, and promote family involvement in this process.
This study investigated the association between colonization of mother-child dyads with Streptococcus mutans (SM) and early childhood caries (ECC), with consideration of the mediator and confounders, using a theoretical model. Four hundred mothers and their children from São Luís, Brazil, were included in the study. A diagram based on directed acyclic graphs was elaborated to analyze the association between SM colonization of the mother, mediated by child SM, and ECC. Other maternal (socioeconomic, waist circumference, sugar consumption, DMFT index, and visible plaque) and child factors (sugar consumption, visible plaque, and child age) composed the theoretical model. A total effect model (maternal SM on ECC) and a direct effect model, adjusted by the mediation effect of child SM (maternal SM via child SM) on ECC, were analyzed. The outcome of interest in this study was ECC (number of teeth with caries experience, dmft), which was analyzed as a discrete variable by Poisson regression. The Paramed test was used to analyze mediation. The following variables were associated with ECC in the total effect model: maternal SM, maternal waist circumference ≥80 cm, DMFT, maternal visible plaque, child age ≥4 years, and increased sugar consumption of the child (>3 times/day). In the direct effect model, high maternal SM levels remained associated with ECC, while moderate and high colonization of the child with SM was also associated with ECC. Child SM colonization just partially mediated the effect of maternal SM on ECC (33%). Thus, factors other than the mechanism of bacterial colonization should be considered in mother-child dyads, including eating habits, oral hygiene practices, and a family history of caries.
Objective: To relate the occurrence of severe childhood caries with nutritional, socioeconomic and behavioral factors among preschool children. Material and Methods: This cross-sectional study included 111 children aged 18-36 months who sought dental care in basic health units of São Luis, Brazil. The oral health status was measured by the DMFT index (number of decayed, missing and filled teeth), IPV/ISG. Socioeconomic, nutritional and behavioral data were collected through a questionnaire applied to parents. Caries Group was defined as DMFT ≥ 1. Data were analyzed using the Chi-square test and Fisher exact test. Poisson regression models and incidence rate ratio (IRR) were used for multivariate analysis, adopting significance level of 5% and confidence interval (CI) of 95%. Results: It was observed that 61 children (55%) were free from caries and 50 (45%) had the disease. In the Caries Group, 38 (76%) had white spot lesions, 70% had the habit of consuming sweets between meals (p=0.04) and the sucrose intake frequency was considered high (3x daily). After multivariate analysis, age (IRR=1.05, 95%CI=1.03 to 1.07, p <0.001) and consumption of sweets (IRR=1.46, 95%CI=1.11 to 1.92 p=0.006) were associated with increased incidence of caries. Conclusion: The findings of this study suggest that frequent exposure to sugars in the form of sweets between meals, lack of guidance of mothers on oral hygiene and increased age were determining factors for the occurrence of severe childhood caries.
