摘要:
评价浦东新区儿童第一恒磨牙窝沟封闭的质量及效果,为儿童第一恒磨牙窝沟封闭技术推广实施提供依据.方法 随机抽取浦东新区2012-2014年接受第一恒磨牙窝沟封闭公共卫生服务项目的605名儿童为研究对象,评价研究对象窝沟封闭涂膜保留率;随机抽取2012年未接受第一恒磨牙窝沟封闭的176名儿童作为对照组,评价接受和未接受窝沟封闭儿童第一恒磨牙患龋情况差异.结果 605名儿童实施窝沟封闭1~3年后的涂膜保留率分别为80.26%,70.83%,60.43%,差异有统计学意义(x2=16.46,P<0.01);实施第一恒磨牙窝沟封闭3年后,干预组儿童第一恒磨牙患龋率(4.10%,29/708)低于对照组(7.20%,51/708)(x2=6.41,P<0.05).结论 窝沟封闭作为公共卫生措施可以有效减少儿童第一恒磨牙龋齿的发生.
