Abstract: 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, over six months of water storage. We found that water storage, type of cement, post space pretreatment, and root region were significant factors affecting the push-out bond strength. water storage reduced the bond strength of RelyX Unicem (RU), especially in the apical region (P<0.05). Super Bond C&B (SB) was stronger than the other two cements, sometimes significantly so. The apical region had the lowest bond strength in all circumstances, although the dif-ference was not always statistically significant. Irri-gation with EDTA improved the bond strengths of Panavia F (PF) and RU significantly in each root region (P<0.05). These results showed that water storage decreased the bonding effectiveness of the adhesive resin cements. Irrigation with EDTA after post space preparation was a valuable procedure, especially when used in conjunction with self-etching adhesive or self-adhesive resin cements.

乙二胺四乙酸处理和水储存对不同树脂粘结剂与根管牙本质间粘结耐久性的影响

本文概要：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。
