| 目的: 评价Tetric N-Flow流动树脂应用于窝沟釉质成形封闭术(Enameloplasty Sealant Technique,EST)的临床效果。方法: 以64名6~7岁儿童为研究对象,采用半口对照法,对每位儿童的口腔左右上下第一恒磨牙分别进行EST,其中一侧使用Tetric N-Flow流动树脂,另一侧使用Helioseal F窝沟封闭剂,临床追踪观察2年,记录材料的保留、脱落情况及龋病发生情况,统计学分析相关指标。结果: 在封闭术后半年和1年,两组材料的保存率和龋病发生率均无统计学差异;而封闭术后2年,Tetric N-Flow流动树脂组与Helioseal F窝沟封闭剂组的材料全部保留率分别为91.80%和80.33%,龋病发生率分别为2.46%和9.84%,两组差异均有统计学意义(P<0.05)。结论: 采用Tetric N-Flow流动树脂进行EST的远期效果优于常用的传统窝沟封闭剂,Tetric N-Flow流动树脂是一种良好的窝沟封闭材料,可在临床上推广应用。 |

| Objective: To evaluate the clinical effects of enameloplasty sealant technique(EST)with Tetric N-Flow floweble resin. Methods: 64 children aged 6 to 7years were enrolled to receive EST on their four first permanent molars. Two molars on one side were sealed with TetricN-Flow while those on the other side were sealed with HeliosealF. The sealant preservation rate and the caries occur rencerate were followed up for 2 years. The data were statis tically analyzed. Results: At half year and 1 year follow up, there was nosignific an difference between the sealant preservation rate of group Tetric N-Flow and that of group Helioseal F. So did the caries occurrence rate. At 2 year follow up, the sealant complete preservation rates of group Tetric N-Flow and group Helioseal F were 91.8% and 80.3% respectively, and the caries occurrence rates of two groups were 2.46% and 9.84% respectively. Statis tic alanalysis revealed significant differences(P<0.05)between both these alant complete preservation rates and the caries occur rencerates of groups. Conclusions Tetric N-Flow flowable resin is superior to conventional sealant in long-term clinical effect of EST. Tetric N-Flow flow able resin is excellent sealant material and maybe applied inclinic widely. |
