加强流动树脂在乳牙窝沟龋防治中的作用

The Efficacy of the Strengthening flowable Composite in Preventing and Curing The Pit and Fissure Caries of Deciduous Teeth

目的观察加强流动树脂在防治乳牙窝沟龋中的疗效,为乳牙窝沟龋的防治寻找简便的方法。方法将157例418颗伴深窝沟的乳牙中龋病例随机分为A、B两组,两组同时行窝沟封闭及龋洞充填。A观察组81例以加强流动树脂治疗215颗,B对照组76例以银粉加强型玻璃离子治疗203颗。观察治疗后6个月、12个月两组充填物的完整率、继发龋的发病率、并进行统计学分析。结果 A组在治疗后6月,12月充填物完整率均高于B组,差异有统计学意义。A组在治疗后12月继发龋发病率低于B组,差异有统计学意义(P<0.05)。结论加强流动树脂在乳牙窝沟龋防治上的疗效优于银粉加强型玻璃离子,值得推广。

Objective The aim of this clinical study was to evaluate the pit and fissure caries-prevention and cure effect of the strengthening flowable composite, thus find a more valid method. Methods 157 patients with total 418 teeth, diagnosed with deciduous teeth caries with deep pit and fissure, were randomly assigned to the A or B group. Both groups were received seal- ing and restoring treatment simultaneously. 81 patients in group A were treated by the flowable composite and 76 patients in group B were treated by the GISRR. The amount of the teeth receiving treatment was 215 and 203 respectively. Each group was received statistical analysis in terms of the intact rate of the filler and the morbidity of the secondary caries after 6 months and 12 months re- spectively. Results The 6-month and 12-month intact rate of group A was higher than group B （P 〈 0. 05 ）. The 12-month mor- bidity of group B was higher than group A （P 〈 0. 05）. Conclusion The better efficacy of the composite compared to GISRR indi- cated that the composite was worth popularizing.
