The prevalence of dental caries among boys was slightly higher than that of girls (35.0% vs 34.5%), and the rates of caries among children aged 2-6 years were 1.96, 3.01, 3.17, 3.22 and 3.31 respectively. The caries prevalence increased with age The prevalence of dental caries in the public park was lower than that of the joint venture park (43.7%).
