Abstract
Background: The aim of this study is to compare shear bond strengths of three universal adhesives (3M ESPE Single Bond Universal, G-aenial Bond, (GC, Japan), Clearfil Universal Bond, (Kuraray, Japan) to dentin. Methods: 36 freshly extracted noncarious molar were selected for this study. Occlusal flat dentin surfaces were exposed by cuttuing occlusal enamel and by 600, 800, 1000, 1200 grid paper, standard smear layer was obtained. The teeth were randomly divided into three groups (n=12). Group 1: 3M Single Bond Universal, Group 2: G-aenial Bond (GC, Japan) Group 3: Clearfil Universal Bond (Kuraray, Japan). Adhesives were applied to dentine according to the manufacturers' instructions. The resin composite (Tetric EvoCeram, Ivoclar, Vivadent, Sweeden) of each adhesive system was applied on the bonded dentin surface using an application apparatus (Ultradent Products Inc.). The materials were light-cured according to the manufacturers' instructions by a LED. After 24 hour storage in distilled water at room temperature, the shear bond test was carried out using a universal testing machine with a cross head speed 0.5mm/min. The data were analyzed with One Way ANOVA and post-hoc Tukey tests. Fracture analyzes of all samples were done using a light microscope. Results: Statistical analysis showed no significant differences in shear bond strengths between three groups (p>0.05). 3M Single Bond Universal (14,44 ± 3,38 mPa), G-aenial Bond (12,32 ± 3,75 mPa), Clearfil Universal Bond (11,30 ± 2,92 mPa). Clearfil Universal Bond showed the lowest shear bond strength to dentin. Conclusion: The three tested universal adhesive systems showed similar shear bond strength to dentin. These results should be supported by clinical practice.
