目的了解西安市7~9岁儿童第一恒磨牙窝沟封闭项目开展的质量状况,为促进儿童口腔健康提供参考。方法采取整群随机抽样方法,对2011年4月—2015年11月西安市窝沟封闭项目检查督导的3 344名学生数据资料进行统计学分析。结果 2011年西安市第1次检查窝沟封闭剂涂膜保留率和完全率最低,分别为69.7%和56.9%,其后逐年呈增长趋势,2015年达到87.7%和81.3%。窝沟封闭完全率在三级医院、二级医院、一级医院、口腔诊所分别为81.0%,64.2%,76.8%和70.8%(Z=162.052,P<0.01);各区(县)完好率为55.4%~92.9%(χ2=410.07,P<0.01)。第2次检查窝沟封闭完好率(85.7%)优于第1次检查的(72.9%)(Z=-48.71,P<0.01)。结论西安市儿童窝沟封闭干预质量需要提高,应加强培训和分类指导,严格质量督导和医疗机构退出机制,促进项目质量进一步提升。
Objective To understand the quality status of the first permanent molars pit and fissure sealant project in children aged 7-9 years old in Xi’an and to provide reference for promoting the oral health of children. Methods A cluster random sampling method was used to analyze the data of 3 344 students who were inspected and supervised in the pit and fissure project in Xi’an from April 2011 to November 2015. Results The first test of pit and fissure sealant in Xi’an in 2011 showed the lowest retention rate and completeness rate of 69.7% and 56.9%, respectively, and then increased year by year, reaching 87.7% and 81.3% in 2015. The complete rate of pit and fissure occlusion was 81.0%, 64.2%, 76.8% and 70.8% in the tertiary hospitals, secondary hospitals, primary hospitals and dental clinics (Z = 162.052, P <0.01) 55.4% ~ 92.9% (χ2 = 410.07, P <0.01). The second place was better than the first place (72.9%) in the first place (Z = -48.71, P <0.01). Conclusion The quality of occlusion of children’s fissure septa in Xi’an needs to be improved. Training and classification guidance should be strengthened, strict quality supervision and exit mechanism of medical institutions should be strengthened, and project quality should be further improved.
