目的：1)通过测量修复材料与牙体结构之间的间隙来评价光敏增量充填树脂基复合材料(RBC)的内适合性；2)老化对RBC材料内适合性的影响。方法与材料：将70颗I类窝洞预备的患牙随机分为5组，4组分别用Teter EvoCeram Bulk Fill(TEC)、SonicFill(SF)、Quixx After Restorative(QX)和X-tra Fill(XF)进行修复；第5组用增量填充Filtek超级通用修复体(FSU)修复。每组各有一半的标本进行热循环。对每颗牙齿进行切片，记录数字图像，并测量任何现有间隙的尺寸。结果：除QX和TEC外，FSU的空隙测量值最小(P<0.05)。
Objectives: To evaluate 1) the internal adaptation of a light-activated incremental-fill and bulk-fill resin-based composite (RBC) materials by measuring the gap between the restorative material and the tooth structure and 2) the aging effect on internal adaptation.Methods and materials: Seventy teeth with class I cavity preparations were randomly distributed into five groups; four groups were restored with bulk-fill RBCs: Tetric EvoCeram Bulk Fill (TEC), SonicFill (SF), QuiXX Posterior Restorative (QX), and X-tra fil (XF); the fifth group was restored with incremental-fill Filtek Supreme Ultra Universal Restorative (FSU). One-half of the specimens of each group were thermocycled. Each tooth was sectioned, digital images were recorded, and the dimensions of any existing gaps were measured. Data were analyzed using analysis of variance (alpha=0.05).Results: FSU had the smallest gap measurement values compared with the bulk-fill materials except QX and TEC (p
