Objective:To know the prevalence of dental caries among 5-year-old children in Chongqing to provide evidence for effective programs in preventing dental caries.Methods:Based on The Guideline for the Third National Oral Health Survey
with nonproportional stratified cluster sampling method
746 children(373 boys and 373 girls) aged 5 years old in six districts of Chongqing were examined.Results:The prevalence rate of dental caries was 64.34%
mean dmft was 3.57 and filled tooth rate was 0.60%.The prevalence rate and the mean dmft in rural were higher than those in urban(P<0.01)
while filled tooth rate in urban was higher than that in rural(P<0.01).There was no significant difference between male and female groups(P>0.05).Conclusion:The dental caries among 5-year-old children in Chongqing is prevalent
but the filled tooth rate is very low.The preventive measure of dental caries should be enhanced.
