摘要
目的了解青岛市市南区小学生龋齿发病情况,评价龋齿预防综合干预2年效果。方法 2010年在青岛市市南区(实验组)、四方区(对照组)调查7、9岁共926名小学生乳牙及恒牙患龋情况,其中仅实验组9岁小学生进行了2年综合干预。结果两组7岁小学生乳牙、第一恒磨牙的患龋率及龋均无显著差异(χ2=1.49～3.32,t=1.33～1.75,P>0.05)。实验组9岁小学生乳牙患龋率、龋均较对照组显著下降(χ2=14.69,t=2.76,P<0.01),第一恒磨牙患龋率、龋均也较对照组显著下降(χ2=6.27,t=2.41,P<0.05)。结论龋齿预防综合干预2年防龋效果明显。
Objective To investigate the caries status of children in priraary schools in southen district of Qingdao, and assess the efficacy of 2-year comprehensive intervention, Methods A survey of the prevalanee of caries of deciduous and perma nent teeth was carried out in 926 children of seven and nine years old, in 2010, in the southen district （experimental group） and Si- fang district （control group） of Qingdao, of which, a two-year comprehensive intervention was conducted only for those of nine- year old children in the experimental group. Results The caries prevalence rates of milk tooth and sixth-year mMar of seven- year-old children in both groups did not show significant difference （x^2= 1.49-3.32 ,t= 1.33-1.75 ,P〉0.05）. In the experimen- tal group, the prevalance rates of caries of milk tooth and sixth-year molar in nine-year-old children were lower than that in the con- trol（x^2=14.69,t=2.76,P〈0.01） and （x^2=6.27,t=2.41,P〈0.05）, respectively. Conclusion Efficacy of two-year com- prehensive prevention of caries is notable.
