Obesity and dental caries are increasing epidemics,especially among children and adolescents.This epidemiological observational cross-sectional study was conducted to assess the possible association between body mass index(BMI) and dental caries among 111,792 school children and adolescents in Jiangsu Province.We found that 13.14% participants of the study sample were overweight,and 7.37% were obese.The prevalence of dental caries was 12.95% in overweight and 7.89% in obese students.There were significant differences in caries prevalence by sex,region,age group,and BMI.Overweight and obesity statuses were associated with dental caries among the study population.BMI and dental caries present a continuous health problem.Thus,we recommend that oral health promotion be used for caries prevention and control.
