目的评价窝沟釉质成形封闭术和普通窝沟封闭术的临床效果。方法 98例7~9岁儿童行第一恒磨牙窝沟封闭,并以其左侧第一恒磨牙采用窝沟釉质成形封闭术作为观察组,右侧第一恒磨牙采用普通窝沟封闭术作为对照组,术后5 a对2组窝沟封闭剂保留及龋损进行评价。结果观察组成功率92.3%,对照组69.4%,2组比较差异有统计学意义(P<0.01)。结论窝沟釉质成形封闭术是预防龋病的有效方法,可使窝沟封闭剂保留率增高,龋齿发生率降低。
Objective To evaluate the clinical effect of foramen omentum closure and ordinary pit and fissure sealant. Methods A total of 98 children aged 7 to 9 years old were enrolled in the first permanent molars pit and the first permanent molars on the left side were treated with foramen omentum en bloc occlusion. The right molars were treated by common pit and fissure occlusion In the control group, the retention of fissure sealant and the carious lesions were evaluated 5 days after operation. Results The success rate of the observation group was 92.3%, while that of the control group was 69.4%. There was significant difference between the two groups (P <0.01). Conclusion The fissure enamel sealing is an effective method to prevent dental caries, which can increase the retention rate of fissure sealant and reduce the incidence of dental caries.
