窝沟封闭术防龋效果观察

Effect of observation on anti-caries of pit and fissure sealant

目的评价窝沟封闭术预防龋病的效果。方法选择本院口腔科门诊收治的56例儿童作为研究对象,在上、下第1恒磨牙进行窝沟封闭,选择同一儿童的对侧上、下第1恒磨牙为对照组,不进行窝沟封闭。进行3年随访观察,观察试验组的封闭剂保留情况,观察两组的患龋率。结果治疗后复查3年,治疗组1、2、3年后封闭剂保留完整率分别为94.8%、89.6%、84.8%,3年中封闭剂保留完整率差异无显著性;试验组1、2、3年后患龋率分别是1.9%、2.8%、4.0%,对照组1、2、3年后患龋率分别是8.9%、16.0%、29.3%,试验组与对照组比较患龋率差异均有统计学意义。结论窝沟封闭技术操作相对简单,成本较低,能起到有效预防龋病的作用。

Objective To evaluate the preventive caries effect of pit and fissure sealant. Methods 56 cases of children in our dental clinic were treated as research subjects in the upper molars for sealant Paragraph 1, and selected the same on the opposite side of children, Paragraph 1 molars as the control group, without fissure closed. Reservations of pit and fissure sealant were observed in the experiment group with 3-year follow-up, and the incidence of caries was observed between the two groups. Results After treatment for 3 years, the retention rates of pit and fissure sealant in the experiment group were 94.8%, 89.6%, 84.8% after 1, 2 and 3 years of the fissure sealing, respectively. The retention rates of pit and fissure sealant did not have significant difference in 3 years; the incidence of caries in the experimental group were 1.9%, 2.8%, 4.0% after 1, 2, and 3 years, respectively, when the incidence of caries in the control group were 8.9%, 16.0%, 29.3%, respectively, there were significant differences in the caries rate between the experiment group and the control group. Conclusion Pit and fissure sealant technology is relatively simple, low cost, can play an effective role in the prevention of dental caries.
