Shear bond strengths to dentin were determined with six current-generation resin adhesive systems following air abrasion of the dentin surface with aluminum oxide and hydroxyapatite. In addition, scanning electron microscopy was used to examine the effects of air abrasive techniques and conditioners/primers on the dentin surfaces. Altering the dentin surface with air abrasion using aluminum oxide and hydroxyapatite did not enhance dentin bond strengths with current-generation adhesive systems. Air abrasion of dentin with aluminum oxide created more surface irregularity than hydroxyapatite. Dentin surfaces air abraded with aluminum oxide and the treated with conditioners that removed the smear layer appeared more irregular than flat ground dentin surfaces treated with the same conditioners.
在用氧化铝和羟基磷灰石对牙本质表面进行空气磨蚀后，使用六种新一代树脂粘结剂系统测定了与牙本质的剪切粘结强度。此外，还使用扫描电子显微镜检查了空气磨蚀技术以及调节剂/底漆对牙本质表面的影响。使用氧化铝和羟基磷灰石通过空气磨蚀改变牙本质表面，并不会增强新一代粘结剂系统与牙本质的粘结强度。用氧化铝进行空气磨蚀产生的牙本质表面不规则性比羟基磷灰石更多。用氧化铝进行空气磨蚀然后用去除玷污层的调节剂处理的牙本质表面，比用相同调节剂处理的平面磨平牙本质表面显得更不规则。
