A laboratory study was conducted to determine the bond strength of composite to enamel and dentin using a one-component dental adhesive system (Prime & Bond 2.1) with three application regimens ranging from four to seven procedural steps. In addition, the effect of acid conditioning of dentin on bond strength was evaluated. Enamel bond strengths ranged from 29.2 to 29.8 MPa, and dentin bond strengths ranged from 18.6 to 21.3 MPa. Enamel bond strengths were significantly higher (P = 0.000) than dentin values. There was no significant difference (P > 0.05) among the bond strengths in either the enamel or dentin groups using the three application regimens. Nor did acid conditioning of dentin increase bond strengths (P = 0.683).
进行了一项实验室研究，以使用单组分牙科粘结系统（Prime & Bond 2.1），通过四到七个操作步骤的三种应用方案来测定复合材料与牙釉质和牙本质之间的粘结强度。此外，还评估了牙本质酸处理对粘结强度的影响。牙釉质粘结强度范围为29.2至29.8兆帕，牙本质粘结强度范围为18.6至21.3兆帕。牙釉质粘结强度显著高于牙本质值（P = 0.000）。使用三种应用方案时，牙釉质组或牙本质组的粘结强度之间没有显著差异（P > 0.05）。牙本质酸处理也未增加粘结强度（P = 0.683）。
