Abstract
This in vitro study was undertaken to investigate the effects of an optional etching step with 35% phosphoric acid or double curing time on the shear bond strength (SBS) of one-step self-etch adhesives to dentin. A significant improvement in shear bond strength was demonstrated when dentin was acid-etched with 35% phosphoric acid prior to the application of one-step self-etch adhesives. The use of curing time double that was recommended by the manufacturers of the respective adhesives was capable of increasing the bond strength of the Single Bond Universal Adhesive but not that of the other two adhesives (Xeno® V+ and AdheSE®One F VivaPen), indicating that the bond strength is adhesive-dependent. Therefore, the use of phosphoric acid-etching on dentin is highly recommended, followed by one-step self-etch adhesives.
采用体外实验研究了35%磷酸选择性蚀刻步骤和两倍固化时间对一步自蚀刻胶粘剂与牙本质剪切结合强度(SBS)的影响。在应用一步自蚀刻粘合剂之前，用35%磷酸对牙本质进行酸蚀刻，可以显著改善剪切粘合强度。使用各自粘合剂制造商推荐的两倍固化时间能够提高单键通用粘合剂的粘合强度，但不能提高其他两种粘合剂(Xeno®V+和AdheSE®One F VivaPen)的粘合强度，表明粘合强度与粘合剂有关。因此，强烈建议在牙本质上使用磷酸蚀刻，然后使用一步自蚀刻粘合剂。
