流体树脂应用于乳前牙美容修复的效果评价

目的 观察光固化流体树脂美容修复乳前牙龋的临床疗效.方法 对65例169颗两侧同名乳前牙分别采用两种不同的树脂充填方法.试验组:85颗乳前牙龋在磨除龋坏牙体组织后应用流体树脂修复牙釉质龋40颗(试验组A);复合树脂与流体树脂联用修复牙本质龋45颗(试验组B);对照组:84颗乳前牙龋直接应用复合树脂修复,其中牙釉质龋37颗(对照组A),牙本质龋47颗(对照组B).评价两组修复后3个月、12个月、36个月的修复成功率.结果 4组修复后3个月、12个月修复成功率比较差异无统计学意义(P均＞0.05);36个月后复查,试验组牙釉质龋和牙本质龋修复成功率分别为88.6%、87.2%,均高于对照组的65.6%、61.9%,差异有统计学意义(P均＜0.01).36个月后试验组在修复体破损程度、边缘变色程度、色泽协调、继发龋发生率方面均优于对照组(P＜0.05).结论 流体树脂对乳前牙美容修复疗效确切,值得临床推广应用.

Clinical Application of Flowable Resin to Anterior Primary Teeth for Aesthetic Restoration

Objective To evaluate the clinical effect of light-cure flowable resins on the aesthetic restoration of anterior primary teeth caries.Methods Two different preventive restorative treatments were applied to anterior primary teeth in 65 patients(169 teeth).Test group:85 anterior primary teeth were removed their caries tissue,in which 40 teeth of enamel caries were treated with Wave Flow flowable resins(test group A) and 45 teeth of dentine caries were treated with Wave Flow flowable resins and composite resin(test group B).Control group:84 anterior primary teeth were treated with composite resin,in which 37 teeth of enamel caries were treated with composite resin(control group A) and 47 teeth of dentine caries were treated with composite resin(control group B).The successful rates on the 3rd,12th,36th month after the restoration of anterior primary teeth caries were analyzed.Results The patients were followed up for 3 years.There was no statistical difference in the successful rate on the 3rd,12th month after the restoration of anterior primary teeth caries between the four groups(P>0.05).But after 36-month follow-up,the film coating retention rates of test group A and B were 88.6%,87.2%,which significantly higher than those of control group A and B(65.6%,61.9%).There was statistical difference between test groups and control groups(P<0.01);Test group was superior to control group in shade,color and secondary caries of restoration(P<0.05).Conclusion Light-cure flowable resin used in the aesthetic restoration of anterior primary teeth is reliable and effective.
