To evaluate the effect of application a new-generation bulk-fill flowable composite resin as an intermediate material between composite resin and dental substrates on micro-leakage in Class V composite restorations.
A total of 144 Class V cavities were prepared in 72 human molars. Specimens were then randomly distributed among three groups according to adhesive system applied (Group 1: Clearfil SE Bond; Group 2: Adper Easy One; Group 3: Adhesive 200T), and each group was divided into three subgroups according to liner material used (Group A: No liner-control group; Group B: Aelite Flo LV, low viscosity microhybrid composite; Group C: Smart dentin replacement). All cavities were restored using resin composite (Aelite LS, low shrinkage posterior composite). Specimens were stained with 0.5% basic fuchsin and evaluated dye penetration.
There was no significant difference in dye penetration was found between the control and the experimental groups.
Micro-leakage is not affected by the application of either conventional or new-generation flowable composite resin as an intermediate material between composite resin and dental substrates.
评估新一代大块充填可流动复合树脂作为复合树脂与牙体组织之间的中间材料应用于Ⅴ类复合树脂修复体时对微渗漏的影响。
在72颗人磨牙上制备144个Ⅴ类窝洞。然后根据所应用的粘接系统将标本随机分为三组(第1组:Clearfil SE Bond;第2组:Adper Easy One;第3组:Adhesive 200T),并且根据所使用的衬层材料将每组再分为三个亚组(A组:无衬层-对照组;B组:Aelite Flo LV,低粘度微混合复合树脂;C组:智能牙本质替代材料)。所有窝洞均使用复合树脂(Aelite LS,低收缩后牙复合树脂)修复。标本用0.5%碱性品红染色并评估染料渗透情况。
对照组和实验组之间在染料渗透方面未发现显著差异。
无论是传统的还是新一代可流动复合树脂作为复合树脂与牙体组织之间的中间材料应用时,均不影响微渗漏。
