Objective To understand the prevalence of dental caries among pupils in Sichuan Tianfu New Area and analyze the effect of dental caries on the growth and development of children to provide evidence for the prevention and control of dental caries in children. Methods The data from the health examination of pupils in Sichuan Tianfu New Area in 2020 were used to collect information on dental caries

height

and body weight of pupils. SPSS 16.0 was adopted to analyze the prevalence and growth and development of dental caries in pupils. The differences in the growth and development of pupils in the caries group and the caries-free group were compared. Results In 2020

the caries rate of pupils in the Tianfu New Area was 42.26%

the number of caries was 1.26±2.08

and the constituent ratio of caries filling was 11.48%. The detection rates of growth retardation

emaciation

overweight

and obesity were 0.39%

4.92%

13.62%

and 12.26%

respectively. The mean height

body weight

and BMI of pupils in the caries group were lower than those in the caries-free group

the detection rate of growth retardation was higher than that in the caries-free group

and the detection rate of overweight and obesity was lower than that in the caries-free group

all with statistically significant differences（all P<0.05）. Conclusion The caries rate of pupils in the Tianfu New Area is high and the filling rate remains low. Dental caries in children may affect their growth and development

and comprehensive interventions are needed to reduce the occurrence of dental caries in children.
