ABSTRACT
The aim of this study was to compare the bond strength to enamel between resin cements combined with total-etch and self-etch adhesive systems and a self-adhesive cement. Eighty bovine incisors had their buccal surface ground flat exposing a plane area in the enamel. Eighty Artglass resin cylinders measuring 3 mm in diameter and 4 mm in height were fabricated. The teeth were divided into eight groups of 10 teeth each and the resin cylinders were cemented with different adhesive systems and resin cements G1 RelyX Unicem (self-adhesive cement); G2 H3PO4 + Single Bond + RelyX ARC; G3 AdheSE + Variolink II; G4 H3PO4 + Excite + Variolink II; G5 Xeno III + Enforce; G6 H3PO4 + Prime&Bond NT + Enforce; G7 Bistite Primers 1 and 2 + Bistite II DC; G8 H3PO4 + Bistite Primers 1 and 2 + Bistite II DC. After application of the adhesives, the cylinders were cemented according to manufacturer instructions. The specimens were submitted to 2000 thermal cycles at a temperature ranging from 5±5ºC to 55±5ºC, and shear bond strength was then tested at a velocity of 1 mm/min. The data were analyzed by ANOVA and the TukeyÆs test (á=5%), obtaining a p value of 0.00. The following mean (±standard deviation) bond strength values were observed for each group G1 5.14(±0.99)a; G3 16.23(±4.69)b; G7 17.82(±3.66)b; G5 18.48(±2.88)bc; G8 20.15(±4.12)bc; G4 22.85(±3.08)cd; G2 24.96(±2.89)d; G6 26.07(±1.69)d. Groups followed by the same letters did not differ significantly. For most of the resin cements tested, the application of adhesive systems using acid etching resulted in a higher bond strength when compared to the self-etch adhesive systems and to the self-adhesive cement.
