PURPOSE：To investigate the status of dental caries in children of primary school in Hangzhou City from 2009 to 2011. METHODS：The status of dental caries was examined annually from 2009 to 2011, and the caries prevalence, filling rates, mean DMFT/dmft were recorded. SPSS 13.0 software package was used for statistical analysis. RESULTS：From 2009 to 2011, the caries prevalence of deciduous teeth were 49.27%, 48.09% and 48.33%, mean dmft were 2.78, 2.81 and 2.84, filling rates of deciduous teeth were 3.92 %, 4.31% and 4.28 %, respectively. No significant difference was found in the caries prevalence of temporary teeth, filling rates of temporary teeth, mean dmft. For the permanent teeth, the caries prevalence were 20.24%, 18.48% and 15.85%, mean DMFT were 0.46, 0.41 and 0.33, filling rates were 10.17 %, 15.67 % and 23.00 %, respectively. From 2009 to 2011, the caries prevalence and mean DMFT of permanent teeth was decreased, while the filling rate was increased. CONCLUSIONS：In the past three years, the status of dental caries of permanent teeth shows a remarkable improving tendency in children of primary school in Hangzhou City.
