摘要
目的:追踪观察上海市区372例3岁幼儿3年间乳牙患龋状况变化。方法:选取2005年上海市区6所幼儿园刚入园372例3岁幼儿(男172例,女200例)进行口腔检查,计算乳牙患龋率,龋、失、补牙数(dmft),龋蚀严重指数(CSI)和龋齿充填构成比,追踪观察3a。采用SPSS13.0软件包对结果进行χ2检验、方差分析、SNK两两比较。结果:372例幼儿2005～2007年3年间患龋率分别为40.90%、50.80%和62.40%;dmft分别为2.17±3.38、2.56±3.61和3.15±3.87;CSI分别为6.38±11.16、7.67±12.04和8.73±13.03;龋齿充填构成比分别为5.35%、13.46%和18.15%。3年间患龋率、dmft、CSI、龋齿充填构成比均呈逐年上升趋势,差异有统计学意义(χ2=16.423,P<0.01;F=8.185,P<0.01;F=3.509,P<0.05;χ2=16.423,P<0.05)。乳牙患龋率、dmft在2005年与2006年间、2005年与2007年间有显著性差异(P均<0.05)而2006年与2007年间无显著性差异(P>0.05);CSI仅在2005年与2007年间有显著差异(P<0.05)。2006年的龋齿发病率为10.48%,2007年为11.56%,差异无统计学意义(χ2=2.763,P>0.05)。2005～2007年,男女之间患龋率、dmft、CSI差异均无统计学意义(P>0.05)。结论:该群体幼儿乳牙患龋状况随年龄增长而急剧上升的趋势有缓解迹象;龋齿充填率仍较低,需加强乳牙龋的防治工作。
PURPOSE： To observe the 3 years changes of deciduous teeth caries in 372 children aged 3 years old in Shanghai. METHODS： 372 samples of 3 year-old children from kindergartens in Shanghai were selected for clinical examination.The prevalence of dental caries,mean draft score, caries severity index （CSI） and caries filling rate were calculated. The results were analyzed with SPSS13.0 software package for χ^2 test, ANOVA and SNK. RESULTS： It was found that from 2005 to 2007,the prevalence of dental caries was 40.90%, 50.80% and 62.40%, respectively. The mean draft was 2.17±3.38,2.56±3.61 and 3.15±3.87, respectively. The CSI was 6.38±11.16,7.67±12.04 and 8.73±13.03, respectively. The caries filling rate was 5.35%, 13.46% and 18.15%,respectively. The prevalence of dental caries, mean draft, CSI and caries filling rate increased gradually as the children grew up. There was significant difference among 3 years （χ^2=16.423,P〈0.01 ;F=8.185,P〈0.01 ;F=3.509,P〈0.05 ;χ^2=16.423,P〈0.05）. SNK analysis showed that there was significant difference of draft between 2005 and 2006 ,2005 and 2007 was found. Significant difference of CSI only between 2005 and 2007 .No significant difference of incidence of caries between 2006 and 2007 was found. There was no significant difference between male and female in prevalence of dental caries,mean dmft,CSI and caries filling rate （P〉 0.05）. CONCLUSION： The trend that the status of dental caries rapidly increases as the children grow up is decreasing in Shanghai;the filling rate is still very low, early prevention and treatment for deciduous caries are needed.
