“…Maternal age <25 y and >35 y were both associated with higher child caries prevalence. Children of young mothers were particularly at risk, in agreement with previous studies (Julihn et al 2009; Dobloug and Grytten 2016). Young mothers often have lower education and income and more often live in a single household (Mattila et al 2000).…”

Introduction:Maternal health during pregnancy plays a part in child health, and several conditions have been associated with adverse child outcomes.Objectives:To determine the socioeconomic determinants and maternal health factors associated with dental caries in young children.Methods:This cross-sectional study is part of a register-based cohort study including all children who were born from 2000 to 2003 and were residing in Stockholm County, Sweden, at age 3 y (n = 73,658). The study followed the cohort until individuals were 7 y old. The final study cohort comprised all children examined at 3 and 7 y (n = 65,259). Data on socioeconomic conditions, maternal health, and maternal health behavior were extracted from Swedish national registries. The multivariate analyses used 2 outcomes: caries experience at age 3 and 7 y (deft > 0 [decayed, extracted, and filled teeth]).Results:The results of this study show that socioeconomic and maternal health behaviors during pregnancy are important determinants of oral health in their preschool offspring. When all significant risk factors were present, the cumulative probability of being diagnosed with dental caries at age 7 y was 75%.Conclusion:This study also showed that maternal obesity and smoking during pregnancy were predictors of dental caries in preschool children. Strategies must be developed for increasing maternal motivation and self-efficacy and providing mothers with knowledge and caries-preventive tools.Knowledge Transfer Statement:The results of this study inform clinicians about the importance of including a more detailed history regarding maternal health and maternal health behaviors during pregnancy to assess caries risk in preschool children. Education, income, and other socioeconomic factors are difficult to modify in the short term. Therefore, strategies must be developed to increase parental motivation and self-efficacy to give parents the determination, knowledge, and tools for prevention.

“…In a Norwegian study, the correlation between siblings aged 6 to 18 in caries was analysed. A strong family effect, with a between-family variability in the range of 13–29% was noted [ 19 ]. In a recent Danish study comparing 15-year-olds and their biological siblings born within three calendar years, a substantial familial aggregation of caries was described, with caries in the corresponding sibling as the most important caries predictor [ 12 ].…”

Objectives This study analysed if children of families in need of dental interventions can be identified by using the caries status of the first-born child as a predictor for caries in younger siblings of the same family. Material and methods All children aged 4 to 15 years, i.e. 13,596 children, visiting a compulsory school in the canton of Basel-Stadt, Switzerland, during the school year 2017/2018 were analysed. Total caries experience and untreated carious lesions at time of examination were recorded as well as a subset of socioeconomic factors such as gender, age, nationality, birth order and the family’s place of residence. Results A total of 6738 schoolchildren who had at least one sibling of school age could be included. Differences in caries experience and the presence of active carious lesions were found for age, nationality and place of residence but not for gender or birth order. Younger siblings had odds of having a history of caries 3.7 times higher (95% confidence interval: 3.0–4.4) and odds of having active carious lesions 3.5 times higher (95% confidence interval: 2.6–4.7) if the eldest child in the family already had caries. Conclusion Caries could be shown to be family-dependent. Younger siblings had a more than three-fold higher risk for caries if the first-born child already had carious lesions. Clinical relevance Based on these results, the caries status of the first-born child could be used as a potential indicator to detect vulnerable families and to initiate targeted preventive measures.

“…Familial aggregation of caries was observed in the Swedish Vipeholm studies undertaken in the 1950s (Krasse 2001). Sibling correlation in caries experience was recently reported in a large Norwegian registerbased study on children aged 6 to 18 y (Dobloug and Grytten 2016). A smaller study in the United States, conducted on 837 children ≤14 y of age (from 333 households), also observed significant sibling-specific concordance of caries in multichild households (Wen et al 2017).…”

Introduction: Social and family conditions are likely of great importance to dental health; however, limited evidence of familial aggregation of caries among adolescent siblings exists. Moreover, social and family-level factors have never been evaluated as isolated caries predictors at the individual level. Objectives: The objectives were to evaluate socioeconomic patterning of caries among siblings, assess sibling-specific aggregation of caries within families, and examine if such aggregation differed by parental socioeconomic position (SEP). We also evaluated the discriminant ability of sibling caries, SEP, and other social and familial factors in predicting caries in cosiblings. Methods: This nationwide register-based study included all 15-y-olds in Denmark in 2003 (index siblings) and their biological siblings born within ±3 y (cosiblings). Clinical and sociodemographic data for each subject were compiled from Danish national dental, social, and population registers. Caries was measured by the decayed, missing, and filled tooth surfaces (DMFS) index. Predictors included SEP (parental education, income, and occupational social class), gender, birth order, immigration status, and household type. Adjusted SEP-caries associations were estimated using negative binomial regression. Familial aggregation was evaluated using adjusted pairwise odds ratios from alternating logistic regressions. Caries prediction was based on classification and regression tree (CART) analyses. Results: The study included 23,847 sibling pairs (n = 47,694). Socioeconomic patterning of caries was similar among the index and cosiblings with significant graded SEP-caries associations. Significant sibling-specific aggregation of caries was observed; cosiblings of caries-affected index siblings had odds of having caries 3.9 times (95% confidence interval: 3.65–4.18) as high as that of cosiblings with caries-free index siblings. This sibling similarity was stronger in socioeconomically disadvantaged families (adjusted pairwise odds ratios: 3.08–5.47). CART revealed index sibling caries as the single most important caries predictor, with caries predicted in ≥84% of cosiblings of adolescents with ≥3 carious tooth surfaces. Conclusions: Caries in a sibling should prompt preventive family-based approaches targeting cosiblings. Knowledge Transfer Statement: This study revealed significant socioeconomic patterning of caries in adolescent siblings. Prediction modeling indicated that the single most important caries predictor among cosiblings was index sibling caries. Information on sibling caries level should be routinely combined with clinical evaluation to identify children at risk. Moreover, information on social and family conditions should be used to target prevention and health promotion at the school or municipal level. These approaches could possibly contribute to reducing the existing caries inequalities.
