Bottom Line: The prevalence of dental caries among the 744 children aged 8 years participating in this survey was 86.3%.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's correlation.

ABSTRACT

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'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.

Pearson's correlation of BMI and caries experience. (a) Caries severity was evaluated by (dmft + DMFT) values (b) dmft values. Pearson's correlation between caries severity and BMI index was significant (P = 0.004 for (a) and P = 0.04 for (b))

Figure 2: Pearson's correlation of BMI and caries experience. (a) Caries severity was evaluated by (dmft + DMFT) values (b) dmft values. Pearson's correlation between caries severity and BMI index was significant (P = 0.004 for (a) and P = 0.04 for (b))

Mentions: Values of dmft/(dmft + DMFT) in each BMI group were compared and the results showed statistically significant differences between different BMI groups [P < 0.1 for (dmft + DMFT), P < 0.01 for dmft] [Table 3], with the highest dmft/(dmft + DMFT) values in the underweight group. No significant difference was found in the caries prevalence between different BMI groups [Table 3]. Pearson's correlation between dmft/(dmft + DMFT) and BMI was significant [P = 0.04 for dmft, P = 0.004 for (dmft + DMFT)], with R values of −0.075 and −0.104 for dmft and (dmft + DMFT), respectively. These results indicated an inverse relationship between BMI and caries severity [Figure 2].
