The aim of this study was to evaluate the compatibility between five self-etching bonding systems (SEBSs) and two resin luting cements (RLCs) assessed by use of an in vitro dentin shear bond test.
The selected RLCs were: Variolink II in a dual-cure mode and Multilink in a self-cure mode. The SEBSs combined with the RLCs were: two one-step SEBSs (One Up Bond F and Xeno III) and three two-step SEBSs (Clearfil SE Bond, Unifil Bond, and Xeno III primer coupled with Clearfil SE Bond bonding resin as an experimental combination). One hundred fifty human molars were divided into ten groups of fifteen samples each. The samples were tested in shear after seven days of storage at 100% RH and 37°C. After each test, the failure mode was recorded.
Significant differences in shear bond strength (SBS) were observed according to both the curing mode of the RLC and the adhesive. The one-step systems Xeno III and One Up Bond F revealed a total incompatibility when bonded with the chemical-curing RLC. Conversely, the two-step SEBSs were compatible with chemical and dual-curing RLC. Failure modes and shear values were in good agreement. A positive correlation was found between the pH of the tested adhesive solutions or resins and the SBS data
本研究旨在通过体外牙本质剪切粘结试验评估 5 种自酸蚀粘结系统（SEBS）与 2 种树脂水门汀（RLC）的兼容性。
选择的 RLC 为：双固化模式下的 Variolink II 和自固化模式下的 Multilink。与 RLC 结合的 SEBS 有：两种一步式 SEBS（One Up Bond F 和 Xeno III）和三种两步式 SEBS（Clearfil SE Bond、Unifil Bond 和 Xeno III 底漆与 Clearfil SE Bond 粘结树脂的实验组合）。150 颗人磨牙分为 10 组，每组 15 个样本。在 100%相对湿度和 37°C 下储存 7 天后，对样本进行剪切测试。每次测试后，记录失效模式。
RLC 和粘结剂的固化模式均显著影响剪切粘结强度（SBS）。当与化学固化 RLC 结合时，一步式系统 Xeno III 和 One Up Bond F 显示出完全不兼容。相反，两步式 SEBS 与化学和双重固化 RLC 兼容。失效模式和剪切值吻合较好。发现测试粘结剂溶液或树脂的 pH 值与 SBS 数据之间存在正相关关系。
