Summary:Self-adhesive cements are the most recent class of cements based on resin composites designed to secure prosthetic restorations to dental tissues. Compared to classic resin-based cements, they are more attractive to dentists since preconditioning of the substrates is not required. Nevertheless, their adhesive performance has not been evaluated thoroughly. An attempt was made to evaluate and compare the shear bond strength of three resin self-adhesive cements, viz. MaxcemElite (Kerr) - ME, Biscem (Bisco) - BC, Rely XU100 (3MEspe) - RU and a classic version of resin cement - Variolink II ( Ivoclar) - VL to ceramic substrates, viz. glass matrix and zirconia. The results evaluated by one-way ANOVA testing indicated no statistically significant differences among the four cements in terms of adhesion to glass-ceramics; the mean values were: 14.33 MPa (ME), 17.55 MPa (BC), 21.45 MPa (RU) and 21.40 MPa (VL). There are differences among the mean values of the four groups analysed for the adhesion to zirconia: 4.9 MPa (ME), 10.84 MPa (BC), 8.2 MPa (RU) and 15.65 MPa (VL).
