| description | Objective: The aim of this study was to evaluate the shear bond strength of universal adhesives applied with self-etch and etch&rinse techniques to dentin.
Materials and Method: Fourty-eight sound extracted human third molars were used in this study. Occlusal enamel was removed in order to expose the dentinal surface, and the surface was flattened. Specimens were randomly divided into four groups and were sectioned vestibulo-lingually using a diamond disc. The universal adhesives: All Bond Universal (Group 1a and 1b), Gluma Bond Universal (Group 2a and 2b) and Single Bond Universal (Group 3a and 3b) were applied onto the tooth specimens either with self-etch technique (a) or with etch&rinse technique (b) according to the manufacturers’ instructions. Clearfil SE Bond (Group 4a; self-etch) and Optibond FL (Group 4b; etch&rinse) were used as control groups. Then the specimens were restored with a nanohybrid composite resin (Filtek Z550). After thermocycling, shear bond strength test was performed with a universal test machine at a crosshead speed of 0.5 mm/min. Fracture analysis was done under a stereomicroscope (×40 magnification). Data were analyzed using two-way ANOVA and post-hoc Tukey tests.
Results: Statistical analysis showed significant differences in shear bond strength values between the universal adhesives (p<0.05). Significantly higher bond strength values were observed in self-etch groups (a) in comparison to etch&rinse groups (b) (p<0.05). Among all groups, Single Bond Universal showed the greatest shear bond strength values, whereas All Bond Universal showed the lowest shear bond strength values with both application techniques.
Conclusion: Dentin bonding strengths of universal adhesives applied with different techniques may vary depending on the adhesive material. For the universal bonding agents tested in this study, the etch&rinse technique negatively affected the bond strength to dentin. |
