本研究的目的是评价五种现有的自酸蚀粘接剂对龈壁龋坏牙本质的粘接能力。本研究选取70颗离体近端牙本质龋患的磨牙。为了在牙龈壁上获得龋齿影响的牙本质，在流水下进行研磨。然后，将试样固定在粘接系统的丙烯酸树脂块和复合树脂中，用塑料环将试样与牙本质粘接，然后通过剪切粘接强度将试样脱粘。使用Clearfil SE粘结剂，粘结到受龋影响的牙本质显示出最高的粘结强度。使用Optibond Solo Plus Self-Etch，与受龋影响的牙本质的粘结显示出比AQ Bond、Tyrian SPE & One-Step Plus和Pitt-L-Pop更高的剪切粘结强度（p<0.05）。Clearfil SE Bond和Optibond Solo Plus Self-Etch与完好牙本质的粘结强度高于Alcant-L-Pop、AQ Bond和Tyrian SPE & One-Step Plus（p<0.05）。总之，除了通过混合层形成的微机械互锁之外，自酸蚀粘合剂与牙本质的粘结强度可以通过功能单体与残余羟基磷灰石之间的额外化学相互作用来增加。本研究的结果证实，自酸蚀粘接剂对龋坏牙本质和健康牙本质的粘接强度的差异是由于化学成分而不是酸度。
The purpose of this study was to evaluate the bonding ability of five current self-etching adhesives to caries-affected dentin on the gingival wall. Seventy extracted human molars with approximal dentin caries were employed in this study. In order to obtain caries-affected dentin on the gingival wall, grinding was performed under running water. Following which, specimens mounted in acrylic blocks and composite resins of the bonding systems were bonded to dentin with plastic rings and then debonded by shear bond strength. With Clearfil SE Bond, bonding to caries-affected dentin showed the highest bond strength. With Optibond Solo Plus Self-Etch, bonding to caries-affected dentin showed higher shear bond strength than AQ Bond, Tyrian SPE & One-Step Plus, and Prompt-L-Pop (p<0.05). Further, the bond strengths of Clearfil SE Bond and Optibond Solo Plus Self-Etch to sound dentin were higher than those of Prompt-L-Pop, AQ Bond, and Tyrian SPE & One-Step Plus (p<0.05). In conclusion, besides micromechanical interlocking through hybrid layer formation, bond strength of self-etch adhesives to dentin may be increased from additional chemical interaction between the functional monomer and residual hydroxyapatite. The results of this study confirmed that differences in bond strength among self-etching adhesives to both caries-affected and sound dentin were due to chemical composition rather than acidity.
