研究了Scotchbond、Clearfil New Bond和Superbond C&B在牛切牙冠段中的牙本质渗透性、牙本质深度和牙本质粘结之间的相关性。由于牙本质表面是在更深的牙本质上制备的，因此牙本质的渗透性在存在玷污层的情况下增加，特别是在去除玷污层之后。一般来说，牙本质越深，Scotchbond、Clearfil New Bond和Superbond C&B的粘结强度越低。Superbond C&B的粘结强度随牙本质渗透性的增加而降低，而Scotchbond和Clearfil New Bond的粘结强度与牙本质渗透性的增加无明显的相关性。Superbond C&B在牙本质各深度的粘接强度均明显高于Scotchbond和Clearfil New Bond。Superbond C&B应被视为牙釉质和牙本质粘结剂。
Correlations among dentin permeability, dentin depth, and dentin bonding of Scotchbond, Clearfil New Bond, and Superbond C&B were studied in bovine incisor crown segments. Since the dentin surface was prepared on deeper dentin, the permeability of the dentin increased both in the presence of, and especially after removal of, the smear layer. In general, the deeper the dentin, the lower the bond strengths of Scotchbond, Clearfil New Bond, and Superbond C&B. The higher the dentin permeability, the lower the bond strength of Superbond C&B, but there was no simple relationship in the case of either Scotchbond or Clearfil New Bond. The bond strength of Superbond C&B was much higher than those of Scotchbond or Clearfil New Bond at any depth of dentin. Superbond C&B should be considered as both an enamel- and dentin-bonding agent.
