摘　　要：目的探讨第一恒磨牙窝沟封闭防龋效果及影响因素。方法 160例行口腔检查的儿童,其一侧的第一恒磨牙采取光固化窝沟封闭,而另一侧同名牙不进行封闭作为对照组,随访3年,观察两侧患龋率,并探讨影响封闭防龋效果的因素。结果随访1年、2年、3年,儿童患龋率随着时间的增加而增加,而观察侧患龋率均显著低于对照侧(P<0.05);性别、牙位、操作者职称对儿童患龋率有显著影响(P<0.05)。结论第一恒磨牙窝沟封闭具有显著的防龋效果,性别、牙位以及操作者职称影响窝沟封闭防龋的效果。Objective To investigate the effect of curing light channel closure of the first permanent molar in preventing caries and to understand the factors affecting the treatment. Method 160 children with oral cavity were chosen as the subjects of study. The first permanent molar on one side was treated with curing light channel closure while the first permanent molar on the other side was treated without. Follow-ups were conducted for 3 years to observe the cases of caries on both sides and to investigate the factors affecting the effectiveness of the sealing method. Findings Follow-ups of the first year,the second year and the third year indicated that caries rate increased as the age increased. The caries rate on the experimental side was significantly lower than that of the control side（ P〈 0. 05）. Gender,tooth location and the qualification of the dentist were found to be the factors affecting the treatment. Conclusion Closure of the first permanent molar can effectively prevent caries. Gender,tooth location and the qualification of the dentist are the factors affecting the treatment.
