摘要
目的了解2013—2015年张家港市幼儿园儿童患龋状况变化及应用氟离子透入预防龋齿的效果,为制定适宜的口腔预防保健措施提供参考。方法于2013年4月采取分层随机整群抽样方法,抽取张家港市13所幼儿园的小班1 743名儿童进行口腔检查,同时采用每年2次的氟离子透入防龋措施,连续追踪3年,计算乳牙患龋率、龋均、龋齿充填率及新龋发生率。结果 2013—2015年患龋人数分别为877,1 083,1 178人;患龋率分别为50.3%,62.1%和67.6%;龋均分别为(2.05±3.03)(3.06±3.78)和(3.45±3.89);龋齿充填率分别为3.22%,6.38%和9.23%。3年间患龋率、龋均、龋齿充填率均呈逐年上升趋势,差异均有统计学意义(χ2/F值分别为113.211,71.533,103.577,P值均<0.05)。2014和2015年的新龋发生率分别为11.82%和5.45%,差异具有统计学意义(χ2=44.802,P<0.05)。结论张家港市儿童乳牙患龋状况随年龄增长而急剧上升的趋势有缓解迹象,氟离子透入能预防乳牙龋齿的发生;但龋齿充填率仍较低,需加强乳牙龋的防治工作。
Objective To observe the 3 years change of deciduous teeth caries among 1 743 children in Zhangjiagang,thus to provide reference for the proper oral hygiene prophylaxis. Methods A total of 1 743 3-year-old children from 13 preschools in Zhangjiagang were selected randomly with stratified and cluster sampling in April of 2013. They were selected for clinical examination annually and received a bi-annual fluoride ion infiltration application. The prevalence of dental caries,mean dmft score,caries filling rate and caries morbidity were calculated.Results It was found that from 2013 to 2015,people who suffered dental caries was877,1 083 and 1 178 respectively.The prevalence of dental caries was 50.3%,62.1%and 67.6%,respectively.The mean number of decayed, missed and filled teeth（ dmft） was（ 2.05±3.03）（ 3.06±3.78）（ 3.45±3.89）,respectively. The caries filling rate was 3.22%,6.38% and 9.23%,respectively.The prevalence of dental caries,mean dmft,and caries filling rate increased gradually as the children grew up.There was significant difference among 3 years（ χ2= 113.211, P〈0.05; F = 71.533,P 0.05; χ2= 103,577,P〈0.05）.The morbidity of caries in 2014,2015 was 11. 82% and 5. 45% respectively. There was significant difference among 2 years（ χ2=44.802, P〈0.05）. Conclusion The trend that the status of dental caries rapidly increases as the children grow up is decreasing in Zhangjiagang.The fluoride ion infiltration can reduce the caries morbidity,but the filling rate is still low,early prevention and treatment for deciduous caries are needed.
