The aims of this study were; to compare the shear bond strength values of resin-based luting cements using etch-and-rinse, self-etching or self-adhesive techniques and to evaluate the effects of pretreatment with 0.2%, and 2% chlorhexidine (CHX) solutions on the bonding stability to dentin.
Ninety specimens were divided into 9 groups of equal sample size (0.2% CHX, 2% CHX and no CHX application groups). Variolink N (multi-step etch-and-rinse technique), Panavia F2.0 (self-etching technique), or RelyX U200 (self-adhesive technique) resin-based luting cement was applied. All specimens were subjected to shear bond strength test (SBS) after bonding procedure. The mode of failure was analyzed by using a stereomicroscope.
There were no significant differences among study groups for the dentin treatment factor. However, for luting cement factor, significant differences were found and Variolink N showed the highest SBS values.
CHX application has no immediate effect on the SBS values of any resin cements. Despite the development of simplified cementation techniques, etch-and-rinse technique is still the most reliable technique because of its high bond strength to dentin.
本研究的目的是比较采用酸蚀冲洗、自酸蚀或自粘结技术的树脂类粘结水门汀的剪切粘结强度值，并评估用0.2%和2%洗必泰（CHX）溶液预处理对与牙本质粘结稳定性的影响。
90个标本被分为9组，每组样本量相等（0.2% CHX组、2% CHX组和未应用CHX组）。应用Variolink N（多步酸蚀冲洗技术）、Panavia F2.0（自酸蚀技术）或RelyX U200（自粘结技术）树脂类粘结水门汀。所有标本在粘结程序后进行剪切粘结强度测试（SBS）。使用体视显微镜分析失败模式。
牙本质处理因素在各研究组之间无显著差异。然而，对于粘结水门汀因素，发现有显著差异，Variolink N显示出最高的SBS值。
应用CHX对任何树脂水门汀的SBS值没有即时影响。尽管粘结技术已发展得更为简化，但由于酸蚀冲洗技术对牙本质具有较高的粘结强度，它仍然是最可靠的技术。
