The aim of this study was to evaluate the influence of Carisolv on the shear bond strength (SBS) of hydrophilic adhesive systems in dentin.
Two hundred bovine incisors were polished with 320- to 1,000-grit aluminum oxide paper and randomly divided into 10 groups (n = 20). The adhesive systems were used according to manufacturer's instructions, and a restorative resin composite (Definite) was inserted in a Teflon matrix and cured. The specimens were kept in humid storage for 7 days at 37 degrees C. The SBS tests were performed in an EMIC universal testing machine with a crosshead speed at 0.5 mm/min. The mean values (MPa +/- [SD]) were analyzed with analysis of variance and Dunnett and Tukey tests.
The results were expressed in decreasing values (MPa): G6 = 18.55 +/- 6.95; G3 = 17.55 +/- 5.73; G2 = 17.05 +/- 5.33; G8 = 16.95 +/- 7.13; G7 = 16.94 +/- 5.22; G4 = 16.31 +/- 3.38; G1 = 15.85 +/- 4.45; G9 = 14.21 +/- 5.87; G5 = 12.89 +/- 3.79; and G10 = 12.31 +/- 5.18.
Carisolv did not interfere in the adhesion to dentin, but its cleanser technique did interfere.
