Objectives: Childhood obesity/underweight status and caries are both important public health problems. This study aims to investigate the caries status and its association with body weight in 8-year-old children in Qingdao, China. Materials and Methods: We initiated a cross-sectional investigation on 744 children aged 8 years during the Oral Health Survey in 2012. Dental caries assessments were carried out and weight status was recorded accordingly. The resulting caries status including caries prevalence, dmft (deciduous dentition), and (dmft + DMFT) (mixed dentition), as well as BMI indices were analyzed for comparison and correlation. Results: The prevalence of dental caries among the 744 children aged 8 years participating in this survey was 86.3%. The caries status represented by dmft (deciduous dentition) and (dmft + DMFT) (mixed dentition) values was 4.31 and 4.85, respectively, and the restoration rate was extremely low, which was no more than 3.0%. Significant difference was found in dmft/(dmft + DMFT) values between different BMI groups, and underweight individuals were found to have the highest dmft/(dmft + DMFT) value. An inverse relationship between body BMI and dmft/(dmft + DMFT) index was identified based on Pearson«SQ»s correlation. Conclusions: A severe state of caries disease was revealed in 8-year-old children in the Chinese city of Qingdao, for whom urgent dental intervention and treatment were needed. Furthermore, underweight individuals were found with the most severe caries experience, indicating caries may affect the development and growth of the afflicted children. Thus, more emphasis should be placed on improving their dental health, with caries prevention being given the priority.
