There is a tendency to interchange dentine adhesives and composite resins when using composite resins for restorations. This study used marginal contraction gaps to test the effect of changing composite resins with a dentine adhesive. Cylindrical butt-joint cavities were prepared entirely in dentine using extracted human teeth. Two groups of control cavities (30 cavities per group) were restored with Prisma-Bond/Prisma-Fil and Heliobond/Heliomolar respectively. Two groups of test cavities (30 cavities per group) were restored using the dentine adhesive. Prisma Universal Bond with Prisma-Fil on one group and Prisma Universal Bond and Heliomolar in the other. Following thermocycling the marginal contraction gaps were measured and assessed. The results showed a significant reduction in marginal contraction gaps when using either composite resin with Prisma Universal Bond. This indicates a compatibility of both resins with the adhesive in this instance.
在使用复合树脂进行修复时，存在将牙本质黏合剂和复合树脂互换使用的倾向。本研究使用边缘收缩间隙来测试更换复合树脂与牙本质黏合剂的效果。使用拔除的人类牙齿在牙本质中制备圆柱形对接洞形。两组对照洞形（每组30个洞形）分别用Prisma-Bond/Prisma-Fil和Heliobond/Heliomolar进行修复。两组测试洞形（每组30个洞形）使用牙本质黏合剂进行修复。一组使用Prisma通用黏合剂和Prisma-Fil，另一组使用Prisma通用黏合剂和Heliomolar。经过热循环后，测量并评估边缘收缩间隙。结果显示，当使用Prisma通用黏合剂与任何一种复合树脂时，边缘收缩间隙都显著减小。这表明在这种情况下，两种树脂与黏合剂都具有相容性。
