目的在这项临床研究中，将可流动树脂复合材料与传统树脂复合材料的8年临床性能进行比较。材料和方法本试验涉及19名参与者的90处非龋性宫颈病变（NCCL）。使用可流动复合材料（Clearfil Flow FX：FX，Kuraray Noritake，日本）或传统树脂复合材料（Clearfil AP-X：AP）结合一步自蚀刻粘合剂（Clearfil S3 Bond）修复NCCL。每个参与者都有两种类型的树脂复合材料，随机分配。在基线时和每年直至8年使用改良的USPHS标准评价了这些疾病。使用Fisher精确检验、Kaplan-Meier方法和多变量Cox回归与脆弱性模型（p< 0.05）对数据进行统计学分析。AP记录了100%的保留率，而FX在8年期间的46个保留率中有4个丢失。无论树脂复合材料的类型如何，边缘染色的发生率都随着时间的推移而增加，8年后AP为48%，FX为57%。仅可流动材料发生树脂复合材料磨损，不同类型的树脂复合材料之间存在显著差异（p= 0.024）。AP组和FX组8年总生存率分别为98%和82（p= 0.110）.结论流动性树脂复合材料在临床使用8年后，与传统复合材料相比，耐磨性较低，存活率较低.临床意义流动性树脂复合材料在长期临床使用后可能会显示出更大的磨损.试验注册号：UMIN 000028745，注册日期：2017年8月19日。
ObjectivesIn this clinical study, the 8-year clinical performances of a flowable resin composite was compared with that of a conventional resin composite.Materials and methodsNinety non-carious cervical lesions (NCCLs) in 19 participants were involved in this trial. NCCLs were restored with a flowable composite (Clearfil Flow FX: FX, Kuraray Noritake, Japan) or a conventional resin composite (Clearfil AP-X: AP) in conjunction with a one-step self-etch adhesive (Clearfil S3 Bond). Each participant had both types of resin composite restorations that were randomly allocated. The restorations were evaluated at baseline and annually up to 8 years using modified USPHS criteria. The data were statistically analyzed using the Fisher’s exact test, Kaplan–Meier method, and a multivariate Cox-regression with frailty models (p< 0.05).ResultsThe 8-year participant recall rate was 95%. One hundred percent retention was recorded for AP, whereas four out of 46 restorations were lost for FX during the 8 years. The incidence of marginal staining increased over time regardless of the type of resin composite, showing 48% for AP and 57% for FX after 8 years. Wear of the resin composite occurred only for the flowable material and there was a significant difference between the types of resin composite (p= 0.024). Overall survival rates at 8 years for AP and FX were 98% and 82% respectively (p= 0.110).ConclusionsThe flowable resin composite presented lower wear resistance and showed a lower survival rate compared with the conventional composite after eight years of clinical service.Clinical relevanceFlowable resin composites may show greater wear after long-term clinical service.Trial registration number: UMIN000028745, Date of registration: August 19, 2017.
