Methods: A cluster random sampling method was used to investigate the caries prevalence in 959 children aged 3 years in Jing’an District. Data was statistically analyzed using SPSS 15.0 software package. Results: The caries prevalence of primary deciduous teeth in 3-year-old children was 28.05%, which was higher in males than in females (P <0.05). The caries was 0.87 and there was no significant difference between men and women. The total filling rate was 5.44%, no significant difference between men and women.
