Abstract

The aim of this study was to evaluate the effect of remaining dentin thickness (RDT) on resin composite bond strength to dentin surfaces when using various adhesive systems. One of three adhesives, Clearfil SE Bond, Single Bond or Clearfil Tri-S Bond, followed by Z100 resin composite were built up on flat dentin surfaces of human molars. The teeth were sectioned obtaining beams with crosssectional areas of approximately 1 mm(2). RDT was measured and microtensile bond strength was determined. Resulting data were categorized into four groups: RDT<2 mm; 2≤RDT<3 mm; 3≤RDT<4 mm; RDT≥4 mm. Clearfil SE Bond showed a correlation between µTBS and RDT. Single Bond showed no significant difference in µTBS for any RDT. The bond strength of resin composite to the different RDT flat dentin surfaces was affected by the adhesive system used.

摘要

本研究旨在评估不同粘接系统中剩余牙本质厚度（RDT）对牙本质表面树脂复合材料粘接强度的影响。三种粘接剂（Clearfil SE Bond、Single Bond 或 Clearfil Tri-S Bond）中的一种，随后用 Z100 树脂复合材料在人磨牙的平坦牙本质表面堆积。将牙齿切割成具有约 1mm(2)的横截面积的梁。测量 RDT 并确定微拉伸粘接强度。所得数据分为四组：RDT<2mm；2≤RDT<3mm；3≤RDT<4mm；RDT≥4mm。Clearfil SE Bond 显示 µTBS 与 RDT 之间存在相关性。Single Bond 在任何 RDT 下的 µTBS 均无显著差异。用于不同 RDT 平面牙本质表面的树脂复合材料的粘接强度受所用粘接系统的影响。
