目的：调查第一恒磨牙窝沟封闭防龋三年的预防效果，分析窝沟封闭涂膜保留率的影响因素。方法采用前瞻设计，按含氟与不含氟封闭剂、粘结剂使用与否、不同职称医师分组对7～9岁儿童2979颗第一恒磨牙进行窝沟封闭；1、3年后通过分层、随机或整群抽样方法复查窝沟封闭涂膜保留率，同时检查第一恒磨牙龋齿发生情况；对所得数据进行统计分析。结果窝沟封闭剂1年复查：总涂膜保留率为87.9%，涂膜保留率与操作者类别相关，与封闭材料及涂粘结剂与否之间未发现显著相关性。窝沟封闭剂3年复查：与未行窝沟封闭组相比，窝沟封闭显著降低第一恒磨牙窝沟面、光滑面龋齿发生牙面数（P＜0.05），龋补牙面降低率为36.1%；窝沟封闭3年含氟封闭剂组光滑面龋发生数明显低于不含氟封闭剂组。结论窝沟封闭能有效预防龋齿发生，含氟封闭剂可能对光滑面龋有一定预防作用；加强技术培训、熟练操作有助于提高窝沟封闭防龋效果。
目的：調查第一恆磨牙窩溝封閉防齲三年的預防效果，分析窩溝封閉塗膜保留率的影響因素。方法採用前瞻設計，按含氟與不含氟封閉劑、粘結劑使用與否、不同職稱醫師分組對7～9歲兒童2979顆第一恆磨牙進行窩溝封閉；1、3年後通過分層、隨機或整群抽樣方法複查窩溝封閉塗膜保留率，同時檢查第一恆磨牙齲齒髮生情況；對所得數據進行統計分析。結果窩溝封閉劑1年複查：總塗膜保留率為87.9%，塗膜保留率與操作者類彆相關，與封閉材料及塗粘結劑與否之間未髮現顯著相關性。窩溝封閉劑3年複查：與未行窩溝封閉組相比，窩溝封閉顯著降低第一恆磨牙窩溝麵、光滑麵齲齒髮生牙麵數（P＜0.05），齲補牙麵降低率為36.1%；窩溝封閉3年含氟封閉劑組光滑麵齲髮生數明顯低于不含氟封閉劑組。結論窩溝封閉能有效預防齲齒髮生，含氟封閉劑可能對光滑麵齲有一定預防作用；加彊技術培訓、熟練操作有助于提高窩溝封閉防齲效果。

Objective To investigate caries prevention effect of pit and fissure sealant on first molar and to analyze the influential factors of sealant retention rate after one and three years. Methods A prospective study was conducted. Pit and fissure sealing was operated on 2979 first molars of 7-9 years children, which were grouped according to the sealant type (with or without fluoride), with or without bonding agent, and level of operators. After 1 and 3 years, approximately 20%of the children were randomly sampled to recheck the sealant retention rate and caries prevalence rate on the first molar. The outcome and influential factors of pit and fissure sealant on first molar were analyzed. Results After one year:general retention rate of the sealants was 87.9%. Operators' level was found to significantly correlate with the retention rate, but not the sealant type and bonding agent. After three years:the number of decayed-filling-surfaces (DFS) in sealant group was significantly lower than that in the control group (P<0.05). The decreasing rate of DFS was 36.1%. Interestingly, the DFS of smooth surfaces using fluoride sealant were significantly lower than that using sealant without fluoride. Conclusions Pit and fissure sealant could prevent the first molar caries effectively, and fluoride sealant seems to have better efficiency on preventing caries on smooth surfaces. Operator training should be strengthened to improve quality of pit and fissure sealant.
