目的比较流动树脂+复合树脂充填与单纯复合树脂充填分别治疗年轻恒磨牙窝沟龋的临床疗效。方法选择156颗患窝沟龋的年轻恒磨牙,常规去龋备洞后,随机分组,实验组78颗患牙采用流动树脂+复合树脂充填,对照组78颗患牙采用单纯复合树脂充填,术后随访2 a,观察有无脱落、微渗漏及继发龋。结果实验组成功率93.6%,对照组成功率74.3%,两组之间差异有统计学意义。结论流动树脂+复合树脂修复年轻恒磨牙窝沟龋的方法是最有效的治疗方法。
Objective To compare the clinical efficacy of mobile resin + composite resin filling and simple composite resin filling in the treatment of young molars pit and fissure caries. Methods A total of 156 young permanent molars with pit and fissure caries were selected and randomly divided into groups. 78 teeth in the experimental group were filled with mobile resin and composite resin while 78 teeth in the control group were filled with pure composite resin. Follow-up 2 a, observe whether the shedding, micro-leakage and secondary caries. Results The experimental group’s success rate was 93.6%, while the control group’s success rate was 74.3%. The difference between the two groups was statistically significant. Conclusion Flow resin + composite resin to repair young molars pit and fissure caries method is the most effective treatment.
