摘　　要：目的:调查杭州市中小学生免费窝沟封闭项目在适龄人群的封闭率和未封闭的原因,探讨提高窝沟封闭在适龄人群中封闭率的可能途径。方法:以封闭率作为窝沟封闭覆盖率的指标,统计适龄人群窝沟封闭的覆盖率和不能封闭的原因。重点关注窝沟封闭列为公共卫生项目后3年间的资料,评估作为公共卫生项目的合理性。结果:适龄人群封闭率平均为52.89%。其中,在进校实施窝沟封闭时,适龄学生牙未萌与未充分萌出、学生和家长不同意是不能封闭的主要原因。结论:现阶段窝沟封闭的封闭率显著偏低,造成未封闭的原因大部分是可控的。通过科学调整,封闭率可大幅提高。应充分考虑牙萌出的时间差异,分时段组织医疗队进校实施窝沟封闭。为体现公共卫生的均等性,对不适宜进行窝沟封闭的适龄学生,可辅助其他口腔预防的适宜技术。PURPOSE： To investigate the coverage of pit and fissure sealants in primary and middle school students of Hangzhou city, and to explore the causes of unsealing students. METHODS： An analysis of sealing rate and unsealing causes of eligible children in Hangzhou city was carried out, using 3-year data of pit and fissure sealants program sponsored by the government. Based on the results, the validity of pit and fissure sealants as a government-sponsored public health program was evaluated. RESULTS： The sealing rate was 52.89%. The main reasons of unsealing were uneruption and incomplete eruption of teeth when the medical teams went to school for pit and fissure sealing. CONCLUSIONS： The main reason of unsealing is eruption issue, which can be controllable. Some scientific adjustments need to be made to improve the coverage, such as increasing sealing times considering the difference of teeth eruption.
