摘要

The adhesive performance on deproteinized dentin of different self-adhesive resin cements was evaluated through microtensile bond strength (|iTBS) analysis and scanning electron microscopy (SEM). Occlusal dentin of human molars were distributed into different groups, according to the categories: adhesive cementation with two-step bonding systems- control Groups (Adper Single Bond 2 + RelyX ARC/ 3M ESPE; One Step Plus + Duolink/Bisco; Excite + Variolink l/lvoclar Vivadent) and self-adhesive cementation-experimental groups (Rely X Unicem/3M ESPE; Biscem/Bisco; Mul-tiLink Sprint/lvoclar Vivadent). Each group was subdivided according to the dentin approach to: a, maintenance of collagen fibers and beta, deproteinization. The mean values were obtained, and submitted to ANOVA and Tukey test. Statistical differences were obtained to the RelyX Unicem groups (a = 13.59 MPa; beta = 30.19 MPa). All the BIS Group specimens failed before the mechanical tests. Dentinal deproteinization provided an improved bond performance for the self-adhesive cement Rely X Unicem, and had no negative effect on the other cementing systems studied.
