To investigate the status of dental caries in children of primary school in Hangzhou City from 2009 to 2011.
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.
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.
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. However, the status of dental caries of deciduous teeth presents no significant improvement.
调查2009年至2011年杭州市小学生龋齿患病情况。
于2009年至2011年每年检查龋齿患病情况,记录龋齿患病率、充填率、恒牙龋均(DMFT)/乳牙龋均(dmft)。采用SPSS 13.0软件包进行统计分析。
2009年至2011年,乳牙龋齿患病率分别为49.27%、48.09%和48.33%,乳牙龋均分别为2.78、2.81和2.84,乳牙充填率分别为3.92%、4.31%和4.28%。乳牙龋齿患病率、乳牙充填率、乳牙龋均差异无统计学意义。恒牙龋齿患病率分别为20.24%、18.48%和15.85%,恒牙龋均分别为0.46、0.41和0.33,充填率分别为10.17%、15.67%和23.00%。2009年至2011年,恒牙龋齿患病率和恒牙龋均呈下降趋势,而充填率呈上升趋势。
过去三年,杭州市小学生恒牙龋齿患病情况呈明显改善趋势。然而,乳牙龋齿患病情况无明显改善。
