摘要
研究目的本研究旨在探讨不同灌洗方案对自粘树脂水泥（SARC）在涂底漆的根状牙本质上的剪切粘结强度（SBS）的影响：方法：将根状牙板（58 个）嵌入丙烯酸树脂中。随后对其进行抛光，并随机分配到五个实验组（N=8-12）和一个对照组（CG，N=8）。使用的冲洗溶液分别为 2.5%次氯酸钠（H）、17%乙二胺四乙酸（EDTA）、9%乙二酸加次氯酸盐（HEDP）、0.9%生理盐水（SS）和 2%洗必泰（CHX）。每个实验组采用不同的冲洗方案，冲洗时间为两分钟：1）H/EDTA/H；2）HEDP；3）H/EDTA/CHX；4）H/EDTA/SS；5）HEDP/SS。CG 样品未经任何灌溉溶液处理。干燥后，使用与 Ultra Tester（Ultradent Products，美国南约旦）相对应的模具将粘接增强底漆（AEP）和双固化 SARC 涂在放射状牙本质上。试样在 37 °C 的蒸馏水中保存，10 天后在剪切模式下破碎。结果采用方差分析和Games-Howell事后检验（α=0.05）进行分析：结果：CG 的 SBS 值最高。除 HEDP 和 HEDP/SS 外，所有实验组的 SBS 都明显低于 CG 组（p 结论：HEDP 似乎是一种适当的治疗方法：HEDP 似乎是在使用 SARC 进行牙本质打底和纤维后粘接之前清洁根管的适当解决方案。
The Impact of Different Irrigation Protocols on the Bond Strength of Self-Adhesive Resin Cement to Radicular Dentin.
Objective: The objective of the study was to investigate the influence of different irrigation protocols on the shear bond strength (SBS) of self-adhesive resin cement (SARC) on primed radicular dentin.
Methods: Radicular dentin slabs (N=58) were embedded in acrylic. Subsequently, they were polished and randomly assigned to five experimental groups (N=8-12) and one control group, CG (N=8). Irrigation solutions used were 2.5% sodium hypochlorite (H), 17% ethylenediamine tetraacetic acid (EDTA), 9% etidronic acid with hypochlorite (HEDP), 0.9% saline solution (SS), and 2% chlorhexidine (CHX). Each experimental group underwent a different irrigation protocol for two minutes: 1) H/EDTA/H, 2) HEDP, 3) H/EDTA/CHX, 4) H/EDTA/SS and 5) HEDP/SS. The CG samples were not treated with any irrigation solution. After drying, the adhesive-enhancing primer (AEP) and dual-curing SARC were applied to the radicular dentin using molds corresponding to the Ultra Tester (Ultradent Products, South Jordan, USA). The specimens were stored at 37 °C in distilled water and broken after 10 days in shear mode. The results were analyzed using ANOVA and post-hoc Games-Howell test, α=0.05.
Results: CG exhibited the highest SBS. With the exception of HEDP and HEDP/SS, all experimental groups showed significantly lower SBS compared to CG (p<0.05).
Conclusions: HEDP appears to be an adequate solution for cleaning the root canal prior to dentin priming and fiber post cementation with SARC.
