Abstract:
Objective To evaluate the microtensile bond strength (μTBS) of five dentin adhesives and their respective fracture modes.Methods The flat dentine surfaces of 75 primary teeth were randomly divided into five groups,which was treated with FL-Bond Ⅱ (group A),Clearfil Protect Bond (group B),Clearfil SE Bond(group C),AdperTM Easy One(group D),and Single Bond 2(group E) respectively.The μTBS was determined with microtensile tester and the fracture mode was observed by scanning electron microscope (SEM).Results The mean μTBS for group A,B,C,D and E was (28.3 ± 2.2),(32.4 ± 2.5),(38.3 ± 2.8),(32.9 ± 3.4) and (23.2 ± 1.9) MPa respectively.There was significant difference between group C and group A,E (P ＜ 0.01),and no significant difference between group C and group B,D.There was no significant difference between group A and group E (P ＞ 0.05).The SEM indicated that there was no significant difference in the fracture mode.Conclusions The bonding property of Clearfil Protect Bond is equivalent to Clearfil SE Bond and AdperTM Easy One,superior to Single Bond 2 and more suitable for primary dentin bonding.
