Özet
Background and Aim: The aim of the present study was to investigate adhesion ability of resin-modified glass ionomer adhesive (Vitrebond) to ethanol-saturated dentin following two different surface conditioning regimes in term of microtensile bond strength test. Materials and Methods: Freshly removed bovine incisors divided into four groups according to surface conditioning and dentin bonding techniques: Group I (37% phosphoric acid [PA]+conventional wet bonding+Vitrebond), Group II (37% PA+ethanol wet bonding+Vitrebond), Group III (polyacrylic acid conditioner [PAA]+conventional wet bonding+Vitrebond), Group IV (PAA+ethanol wet bonding+Vitrebond). After application of Vitrebond, adhesive resin procedures (Single Bond 2) and composite buildups (Valux Plus) were done and bonded teeth were sectioned into sticks with 1 mm2 interfacial area after immersion in water for 7 days. Then microtensile bond strength test was performed. Data were submitted to statistical analyses using two-way ANOVA and Tukey tests. Results: Mean microtensile bond strength values (MPa) were as follows: Group I, 14.32 (3.9); Group II, 11.11 (3.3); Group III, 16.21 (4.7); Group IV 9.96 (2.5). Statistical analysis indicated that ethanol wet-bonding reduced bond strength of Vitrebond significantly, regardless of surface conditioning regimes (p = 0.010 for PA groups, and p < 0.001 for PAA groups). Conclusion: It may be concluded that the saturation of conditioned dentin with ethanol might be deleterious to initial bonding performance of the resin-modified glass ionomer-based dentin adhesives.
