The prevalence of overweight children in the United States continues to increase.
To examine the relationship between being overweight and caries in primary and permanent dentition in a nationally representative sample of children.
Data from the NHANES III (1988-1994) were analyzed using logistic regression and controlling for potential confounders for 10 180 children 2-18 years of age and from the NHANES 1999-2002 for 7568 children 2-18 years of age.
For children 2-5 years of age, there was no difference in caries experience among normal weight, at risk for overweight or overweight children for NHANES III and for NHANES 1999-2002. For children 6-11 years of age (NHANES III), at risk for overweight and overweight children were less likely to have caries experience in the primary dentition than normal weight children; overweight children were less likely to have caries experience in the permanent dentition than normal weight children. For children 12-18 years of age (NHANES III), overweight children were less likely to have caries experience in the permanent dentition than normal weight children. For children 6-11 years of age and 12-18 years of age (NHANES 1999-2002), there was no difference in having caries experience among normal, at risk for overweight and overweight children.
The data from NHANES III and NHANES 1999-2002 provide no evidence to suggest that overweight children are at an increased risk for dental caries. Although no differences in caries rates by weight were found in younger children, interestingly results from NHANES III suggest that being overweight may be associated with decreased rates of caries in older children.

- "Frequent sugar intake is also a recognized risk factor for dental caries. Thus, the eating pattern among overweight or obese children may be a common risk factor in overweight children and dental caries . Given that the strong evidence supporting the relation between dental caries with indiscriminate dietary intake has been linked to the development of obesity at a young age, a link between dental caries and weight is biologically possible .

ABSTRACT: Aim. To correlate the prevalence of dental caries to body mass index, daily sugar intake, and oral hygiene status of 12-year-old school children of Mathura city. Material and Methods. The study design was cross-sectional and included 100 school children aged 12 years (n = 50 boys and n = 50 girls) who were randomly selected from two schools based upon inclusion and exclusion criteria. Body weight/height was recorded and BMI was calculated and plotted on CDC-BMI for age growth charts/curves for boys and girls to obtain percentile ranking. Dental caries was recorded using WHO criteria. Oral hygiene status of the study subjects was assessed using oral hygiene index-simplified. Data regarding the daily sugar intake was recorded using 24-hour recall diet frequency chart. The data obtained was analysed using SPSS version 11.5 for windows. Result. Only 27 subjects were affected by caries. The mean DMFT/dmft was 0.37 ± 0.79 and 0.12 ± 0.60, respectively. Statistical analysis by means of a logistic regression model revealed that only oral hygiene status had a significant effect on caries prevalence (OR = 5.061, P = 0.004), whereas daily sugar intake and body mass index had no significant effect. Conclusion. From the analysis, it was concluded that oral hygiene status had a significant effect on caries prevalence of 12-year-old school children of Mathura city.

ABSTRACT: Background:A balanced nutrition schedule provides the essential substances for proper oral health.Objectives:The aim of this study was to investigate the association between dental caries and body mass index in 6-11 year-old children in Zahedan.Materials and Methods:In this cross-sectional study 1213 children (670 girls, 543 boys) were included. Body mass index (BMI) and clinical examination for determination of DFT (decay filling teeth) index (based on WHO criteria) were taken. Collected data were analyzed using the t-test, chi-square and ANOVA.Results:Among children, 20.8% had low weight, 66.3% normal weight, 7.8% were overweight and 5.1% obese. In the low weight, normal weight, overweight, and obese groups, the mean ± SD values for DFT were: 0.63 ± 1.1, 0.88 ± 1.36, 1.16 ± 1.33, and 0.87 ± 1.31, respectively. There was a significant association between BMI and DFT (P = 0.005). The overweight group had higher DFT compared to the low and normal weight groups. 13.5% of low weight, 12.2% of normal weight, 14.7% of overweight and 22.6% of obese children had DFT = 0. There was no statistical association between BMI and being caries free (P = 0.4).Conclusions:The mean DFT in the overweight group was higher than low and normal weight groups. There was a statistically significant association between BMI and DFT.

- "So by what mechanism does dental decay decrease with increasing obesity? Studies that have reported decreasing dental decay with increasing obesity[15-18] have all concluded that “The relationship between overweight and dental caries in children is far more complex than can be explained by carbohydrate consumption alone.” The largest study based on United States children concluded that “NHANES III and NHANES 1999-2002 provide no evidence to suggest that overweight children are at increased risk for dental caries”.

ABSTRACT: To evaluate the relationship of children's obesity and dental decay.
We measured parameters related to obesity and dental decay in 8,275 4(th) and 5(th) grade Kuwaiti children (average age = 11.36 years) in a cross-sectional study. First to determine body weight, height, age for computation of BMI . Second, to determine numbers of teeth, numbers of fillings and numbers of untreated decayed teeth to determine extent and severity of dental disease. From these measurements, we computed measures of dental decay in children from four body weight categories; obese, overweight, normal healthy weight and underweight children.
The percentage of children with decayed or filled teeth varied inversely with the body weight category. The percentage of decayed or filled teeth decreased from 15.61% (n=193) in underweight children, to 13.03% (n=4,094) in normal healthy weight children, to 9.73% (n=1,786) in overweight children to 7.87% (n=2,202) in obese children. Differences between all groups were statistically significant. Male children in this population had more dental decay than female children but the reduction of tooth decay as a function of BMI was greater in male children.
The finding of an inverse obesity-dental decay relationship contradicts the obesity-sugar and the obesity-dental decay relationship hypotheses. Sugar is well recognized as necessary and sufficient for dental decay. Sugar is also hypothesized to be a leading co-factor in obesity. If the later hypothesis is true, one would expect dental decay to increase with obesity. This was not found. The reasons for this inverse relationship are not currently clear.
