摘　　要：One hundred and twenty single-root teeth were selected to evaluate the bonding durability of three different adhesive resin cements to intra-radicular dentin and the effect of ethylenediaminetetraacetic acid （EDTA） irrigation on bonding durability,树脂粘结材料已广泛应用于临床,但其粘结耐久性仍不尽人意,导致牙本质粘结修复体远期存在继发龋、脱落率高等问题,成为目前亟需解决的关键问题。本文通过探讨不同树脂粘结剂(Supper Bond C&B、Panavia F和RelyX Unicem)与根管牙本质间粘结耐久性的差异,以及乙二胺四乙酸(EDTA)处理对不同树脂粘结剂粘结耐久性的影响,发现EDTA处理可以提高树脂粘结剂与根管牙本质间的粘结强度和粘结耐久性,从而可以提高修复体的远期粘结效果。另外,水储存可造成树脂粘结剂与根管牙本质间粘结强度下降。
