Abstract: Objective To investigate the status quo of caries and its correlation with body mass index(BMI)in 8-year-old children in Laoshan district of Qingdao,China. Methods A cross-sectional study of dental caries was carried out in 933eightyear-old children in public primary schools in Laoshan district of Qingdao,including the rate of caries,the caries status of deciduous and permanent teeth.The data of corresponding body height and BMI were collected to analyze the correlation between caries and BMI. Results The prevalence of dental caries in children surveyed was 76.5%,and the packing fraction of the caries was less than 6.0%.The primary dentition index(PDI)and mixed dentition index(MDI)were 3.66±3.23 and 4.33±3.59,respectively.The difference in PDI among boys and girls was not significant(P>0.05),and that in PDI+MDI was significant.Correlation analysis showed PDI and PDI+ MDI were negatively correlated with BMI(r=-0.238,-0.237;P<0.01). Conclusion The prevalence of dental caries in children of eight years old in Laoshan district of Qingdao is correlated with their BMI.
