目的:探讨窝沟封闭术对预防儿童窝沟龋齿的临床效果分析。方法:将210例6~8岁儿童左右第一、二恒磨进行自身对比分析。预防组:选择210例儿童右侧420颗第一、二恒磨牙予以窝沟封闭术;对照组:选择其对侧未涂布窝沟封闭剂的健康同名牙。观察两组龋齿发生率,以及预防组窝沟封闭剂保留情况。结果:3年后预防组患龋率为7.62%;对照组患龋率为41.4%;两组对比其差异明显(P<0.01),具统计学意义。3年后,预防组窝沟封闭剂保留完好率为81.7%。结论:对6龄齿予以防止性窝沟封闭术,不仅可以增强儿童防龋效果,同时其窝沟封闭剂保留率也明显较高。
Objective: To investigate the clinical effect of pit and fissure sealant in prevention of fissure caries in children. Methods: 210 cases of 6 to 8 years old children around the first and second constant grinding for their own comparative analysis. Prevention group: 420 cases of the first and second permanent molars on the right side of 210 children were selected for pit and fissure occlusion. In control group, the same name of the same dentate was chosen as the uncoated pit and fissure sealant. The incidence of caries in both groups was observed, and the preservation of fissure sealant in the two groups was observed. Results: The prevalence of caries was 7.62% after 3 years in prevention group and 41.4% in control group. The difference between the two groups was significant (P <0.01), with statistical significance. Three years later, the prophylactic pit and fissure sealant retention rate was 81.7%. Conclusion: Preventing pit and fissure occlusion of 6th-old teeth can not only enhance the effect of children’s caries prevention, but also keep the pit and fissure sealant retention rate significantly higher.
