Obesity and dental caries in children are significant health problems. The aims of this review are to identify whether children aged 6 years and younger with overweight and/or obesity have higher dental caries experience compared with children with normal weight and, secondly, to identify the common risk factors associated with both conditions. Medline, Embase, and seven other databases were systematically searched followed by lateral searches from reference lists, grey literature, theses, conference proceedings, and contacting field experts. Longitudinal observational studies addressing overweight and/or obesity and dental caries in children aged 6 years and younger were included. A random effects model meta-analyses were applied. Nine studies were included in this review. Children with overweight and obesity had a significantly higher dental caries experience compared with children with normal weight (n = 6). The pooled estimates showed that difference in caries experience between the two groups was statistically significant. Low levels of parental income and education were identified to be associated with both conditions in the sample population. Children with overweight and obesity are more vulnerable to dental caries. Low levels of parental income and education influence the relationship between the two conditions. However, the quality of evidence varied considerably; therefore, findings should be interpreted cautiously.
