Dyad Flow自粘接流动树脂应用于儿童恒磨牙窝沟龋预防性树脂充填的临床效果评价

Clinical effect evaluation of Dyad Flow self-adhesive flow resin for preventive resin restoration of pit and fissure caries in children′s permanent molars

目的评价Dyad Flow自粘接流动树脂应用于儿童恒磨牙窝沟龋预防性树脂充填(PRR)的临床效果。方法选择2016年6月至2018年6月在广西壮族自治区人民医院口腔科就诊的第一恒磨牙窝沟龋患儿78例(共184颗牙),年龄6~14岁,均以PRR技术备洞。采用随机数字表法将其分为观察组和对照组,观察组39例(95颗牙),采用Dyad Flow自粘接流动树脂进行填充;对照组39例(89颗牙),采用Beautifil Flow Plus F03加强型流动聚合体进行填充。记录两组材料充填操作耗时。在治疗后第6、12、24、36个月进行门诊随访,采用改良版美国公共卫生署(USPHS)评价标准对两组治疗效果进行评价,比较两组填充材料的保留情况。结果在治疗后第6、12、24、36个月,两组在充填体完整性、表面纹理和继发龋方面比较差异不显著(P>0.05)。在治疗后36个月,对照组边缘着色情况显著优于观察组(P<0.05)。生存分析结果显示,对照组的材料保留情况稍优于观察组,但两组差异无统计学意义(log-rank检验:χ^(2)=3.565,P=0.059)。观察组材料充填操作时间短于对照组,差异有统计学意义[(59.52±0.67)s vs(137.56±0.73)s;t=78.557,P<0.001]。结论Dyad Flow自粘接流动树脂和Beautifil Flow Plus F03加强型流动聚合体应用于恒磨牙窝沟龋PRR的效果相近。但Dyad Flow自粘接流动树脂填充操作时间更短,更适用于儿童。

Objective To evaluate the clinical effect of Dyad Flow self-adhesive flow resin for preventive resin restoration(PRR)of pit and fissure caries in children′s permanent molars.Methods Seventy-eight children with pit and fissure caries in the first permanent molar(184 teeth in total)who were treated in the Department of Stomatology of the People′s Hospital of Guangxi Zhuang Autonomous Region from June 2016 to June 2018 were selected.The patients ranged in age from 6 to 14 years,and were all prepared with PRR technology.The patients were divided into observation group and control group by random number table method,with 39 cases(95 teeth)in the observation group who were filled with Dyad Flow self-adhesive flow resin and 39 cases(89 teeth)in the control group who were filled with Beautifil Flow Plus F03 reinforced flowable composite.The time consuming of material filling operations in the two groups was recorded.The outpatient follow-up was performed on the patients 6,12,24,and 36 months after treatment.The evaluation criteria of modified United States Public Health Service(USPHS)was used to evaluate the treatment effects of the two groups,and the retention of filling materials was compared between the two groups.Results There were no significant differences between the two groups in terms of filling integrity,surface texture and secondary caries 6,12,24,and 36 months after treatment(P>0.05).The edge coloration in the control group was significantly better than that in the observation group 36 months after treatment(P<0.05).The results of survival analysis showed that the material retention of the control group was slightly better than that of the observation group,but the difference was not statistically significant between the two groups(log-rank test:χ^(2)=3.565,P=0.059).The material-filling operation time in the observation group was shorter than that in the control group,and the difference was statistically significant[(59.52±0.67)s vs(137.56±0.73)s;t=78.557,P<0.001].Conclusion Dyad Flow self-adhesive flow resin and Beautifil Flow Plus F03 reinforced flowable composite have similar effects on PRR of pit and fissure caries in permanent molars,but Dyad Flow self-adhesive flow resin has shorter filling operation time and is more suitable for children.
