This study compared the effects of different dentin surface treatments on the shear bond strengths of three adhesive systems. The adhesive systems included a resin-modified glass ionomer, Fuji II LC, and two dentin bonding systems, One Step and Scotchbond Multi-Purpose Plus. The surface treatments compared for each adhesive system were as follows: 1) the controls, which were conditioned, 2) air abrasion at 120 psi without conditioning, 3) air abrasion at 160 psi without conditioning, 4) air abrasion at 120 psi with conditioning, and 5) air abrasion at 160 psi with conditioning. The KCP 1000 Whisperjet was used for all air-abrasive specimens. Controls for each adhesive material (Fuji II LC, One Step, Scotchbond Multi-Purpose Plus) were bonded using manufacturers' recommendations. Results showed that air abrasion significantly lowered bond strength of the resin-modified glass ionomer, conditioned or nonconditioned (P < 0.01). Air abrasion alone significantly lowered bond strengths of the dentin bonding agent systems (P < 0.01). However, air abrasion plus conditioning of the dentin surface resulted in bond strengths that were similar to the conditioned-only specimens (P < 0.01).
本研究比较了不同牙本质表面处理对三种粘结系统剪切粘结强度的影响。粘结系统包括一种树脂改性玻璃离子水门汀（Fuji II LC）以及两种牙本质粘结系统（One Step和Scotchbond Multi-Purpose Plus）。针对每种粘结系统比较的表面处理如下：1）对照组，即经过预处理的；2）在120 psi压力下进行空气喷砂且未预处理；3）在160 psi压力下进行空气喷砂且未预处理；4）在120 psi压力下进行空气喷砂并预处理；5）在160 psi压力下进行空气喷砂并预处理。所有空气喷砂样本均使用KCP 1000 Whisperjet。每种粘结材料（Fuji II LC、One Step、Scotchbond Multi-Purpose Plus）的对照组均按照制造商的建议进行粘结。结果表明，空气喷砂显著降低了树脂改性玻璃离子水门汀的粘结强度，无论是否经过预处理（P < 0.01）。单独的空气喷砂显著降低了牙本质粘结剂系统的粘结强度（P < 0.01）。然而，牙本质表面进行空气喷砂加预处理后的粘结强度与仅经过预处理的样本相似（P < 0.01）。
