Abstract

Optimal bonding of adhesive restorations to dentin is crucial to prevent microleakage and enhance the survival of root-filled teeth. The aim of this study was to investigate the effect of chlorhexidine (CHX), alexidine (ALX) and octenidine dihydrochloride (OCT) on the bond strength of resin composites to coronal dentin. Human coronal dentin specimens were treated with 2% CHX, 0.1% ALX, 0.1% OCT or saline then restored with traditional or bulk-fill resin composites. The adhesion strength between the resin and dentin was measured using the microtensile bond strength and failure mode was determined using a stereomicroscope. Treatment with ALX and OCT resulted in significantly greater μTBS compared with CHX and saline, irrespective of the resin composite used. Alexidine treatment predominantly resulted in mixed failure, while adhesive failures were frequently observed in CHX and saline-treated dentin. In conclusion, final irrigation with ALX or OCT improved the bonding of resin composites to dentin.

关于双胍类和吡啶类防腐剂对树脂复合材料与牙本质粘附性影响的实验室研究

粘接修复体与牙本质的最佳粘接对于防止微渗漏和提高根充牙的存活率至关重要。本研究旨在探讨洗必泰（CHX）、洗必泰（ALX）和盐酸辛烯胺（OCT）对树脂复合材料与冠状牙本质粘接强度的影响。用 2% CHX、0.1% ALX、0.1% OCT 或生理盐水处理人类冠状牙本质样本，然后用传统或大量填充树脂复合材料进行修复。使用显微拉伸粘接强度测量树脂与牙本质之间的粘接强度，并使用体视显微镜确定失效模式。与 CHX 和生理盐水相比，无论使用哪种树脂复合材料，ALX 和 OCT 处理都能显著提高 μTBS 值。Alexidine 处理主要导致混合失败，而 CHX 和生理盐水处理的牙本质则经常出现粘接失败。总之，用 ALX 或 OCT 进行最终灌洗可以提高树脂复合材料与牙本质的粘接性。

期刊介绍： The Australian Endodontic Journal provides a forum for communication in the different fields that encompass endodontics for all specialists and dentists with an interest in the morphology, physiology, and pathology of the human tooth, in particular the dental pulp, root and peri-radicular tissues. The Journal features regular clinical updates, research reports and case reports from authors worldwide, and also publishes meeting abstracts, society news and historical endodontic glimpses. The Australian Endodontic Journal is a publication for dentists in general and specialist practice devoted solely to endodontics. It aims to promote communication in the different fields that encompass endodontics for those dentists who have a special interest in endodontics.
