目的研究窝沟封闭剂在儿童正畸中应用的效果。方法选择门诊89例6～14岁正在接受正畸治疗的儿童患者,对其一侧上下第一恒磨牙进行窝沟封闭,另一侧未封闭与之对照,观察双侧患龋情况,随访3年。结果进行窝沟封闭的试验组牙齿患龋率为1.1%,未涂封闭剂组患龋率为8.4%,试验组患龋率明显降低。结论对正畸儿童的牙齿进行有效的窝沟封闭是防龋的有效方法 ,同时也保障了矫治过程的顺利进行。
Objective To study the effect of pit and fissure sealant in children orthodontics. Methods A total of 89 pediatric patients aged 6-14 years undergoing orthodontic treatment were enrolled in this study. The foraminotomy was closed on one side of the first permanent molars, and the other side was not closed to observe the bilateral caries. Follow-up 3 year. Results The dental caries prevalence in trial group was 1.1%, while that in unsealed group was 8.4%. The caries prevalence in the experimental group was significantly lower than that in the control group. Conclusion The effective pit and fissure occlusion of orthodontic children’s teeth is an effective method to prevent dental caries. At the same time, the orthodontic treatment is ensured.
