摘要
目的 :观察对儿童第一恒磨牙实施窝沟封闭术后的防龋效果。方法 :将上海新场社区的2所小学二年级学生分为封闭组(205人)和对照组(209人),对封闭组符合适应症的第一恒磨牙实行窝沟封闭,对照组不做任何处理。3年后随访检查封闭剂保留情况和患龋情况。结果 :共检查2组儿童第一恒磨牙1 639颗,对封闭组儿童344颗符合适应症的第一恒磨牙进行窝沟封闭。3年后,窝沟封闭剂保留率为52.90%;封闭组患龋率为6.25%,对照组患龋率为11.22%。两组差异有统计学意义(χ~2=12.66,P <0.01)。结论:对第一恒磨牙实施窝沟封闭,可有效降低龋齿的发生率。
Objective: To observe the caries prevention effect of the implementation of pit and fissure sealing on the first permanent molar in children. Methods: The second grade pupils of two primary schools in Xinchang Community, Shanghai were divided into a closed group with 205 pupils and a control group with 209 pupils. The pit and fissure sealing was performed on the first permanent molar which met the indications in the closed group, and the control group received no treatment. Follow-up was performed 3 years later to check the retention of the sealant and the caries. Results: A total of 1 639 first permanent molars were examined in children of the two groups, a total of 344 eligible first permanent molars in the closed group were closed. Three years later, the retention rate of pit and fissure sealant was 52.90%;the incidence of caries was 6.25% in the closed group and 11.22% in the control group. The difference between the groups was statistically significant(χ^2 =12.66, P < 0.01). Conclusion: Implementing pit and fissure sealing on the first permanent molar can effectively reduce the incidence of dental caries.
