Abstract:
Objective: To investigate the effect of self-etching adhesive with different unsealing time on the microleakage of the adhesive interface between tooth and resin. Methods: Unopened self-etching adhesives, Scotchbond Universal (S) and Xeno V+ (X) were respectively used to adhere Z350 resin for restoration of the prepared occlusal cavities sized 4 mm × 4 mm × 4 mm (n = 40) . The methylene blue staining method was used to observe the microleakage of the adhesive interface between the tooth and filling material at the instant moment, 1, 2 and 3 months after the self-etching adhesives was opened (n = 10) . Results: (1) Increase of microleakage in S group was found with the time span after unsealing, and there was a statistical difference between the instant moment and 3 months after unsealing (P＜0. 05) . (2) There was no significant difference at the 4 test time points in X group (P＞0. 05), although the microleakage value of the samples were increased with the increase of the time after unsealing. (3) The microleakage of X group was greater than that of S group at the instant moment and 1 month after unsealing (P＜0. 05) . Conclusion: Unsealing time may increase the microleakage of the adhesive interface between the tooth and the filling material, the effect varies with the types of the adhesives.
