To evaluate the immediate microtensile bond strengths achieved with representative adhesive systems from each of the four current bonding approaches.
Resin composite was bonded incrementally to flat, midcoronal dentin from 33 human molars, using the adhesives (Adper Scotchbond MP; Adper Scotchbond 1; Optibond Solo Plus; Clearfil SE Bond; AdheSE; Tyrian SPE + One Step Plus; Optibond Solo Plus self-etching; One-Up Bond F; iBond; Adper Prompt L-Pop; Xeno III) according to the respective manufacturer's instructions. The bonded specimens were immediately sectioned into sticks and underwent microtensile bond testing either immediately or after 24 h. Data were analyzed with two-way ANOVA and LSD tests.
No significant differences were found between immediate and 24-h bond strengths (p > 0.05). However, significant differences were observed among adhesives (p = 0.001). The all-in-one adhesive iBond showed statistically lower values when compared to all the other adhesives. Adper Prompt L-Pop, Xeno III, Tyrian SPE + One Step Plus and One-Up Bond F, all self-etching adhesives, were significantly weaker than AdheSE, Optibond Solo Plus, Adper Scotchbond 1, Optibond Solo Plus self-etching, Clearfil SE Bond, and Adper Scotchbond MP, which did not differ statistically from each other.
Microtensile bond strengths of representative adhesive systems from the four categories of bonding agents were not equivalent, with the lowest values recorded for the one-step self-etching adhesives. There were no differences in the bond strengths when measured immediately and after 24 h.
评估采用当前四种粘结方法中每种方法的代表性粘结系统所获得的即时微拉伸粘结强度。
根据各自制造商的说明，使用粘结剂（Adper Scotchbond MP；Adper Scotchbond 1；Optibond Solo Plus；Clearfil SE Bond；AdheSE；Tyrian SPE + One Step Plus；Optibond Solo Plus自酸蚀粘结剂；One-Up Bond F；iBond；Adper Prompt L-Pop；Xeno III）将树脂复合材料逐步粘结到33颗人磨牙的平坦中冠牙本质上。粘结后的标本立即切成小棒，并立即或在24小时后进行微拉伸粘结测试。数据采用双向方差分析和LSD检验进行分析。
即时粘结强度和24小时粘结强度之间未发现显著差异（p > 0.05）。然而，粘结剂之间观察到显著差异（p = 0.001）。与所有其他粘结剂相比，一体式粘结剂iBond的数值在统计学上较低。Adper Prompt L-Pop、Xeno III、Tyrian SPE + One Step Plus和One-Up Bond F，所有自酸蚀粘结剂，均明显弱于AdheSE、Optibond Solo Plus、Adper Scotchbond 1、Optibond Solo Plus自酸蚀粘结剂、Clearfil SE Bond和Adper Scotchbond MP，它们之间在统计学上没有差异。
四类粘结剂的代表性粘结系统的微拉伸粘结强度并不相同，一步自酸蚀粘结剂的数值最低。即时测量和24小时后测量的粘结强度没有差异。
