Abstract: Background: Gallic acid (GA), as a material with potentially beneficial effects in dentistry, was used in this study to investigate whether it affects the shear bond strength of composite to the dentin via self-etch and total-etch strategies of a universal adhesive.Material and Methods: Sixty intact molars with sectioned flat occlusal surfaces were treated with 1 wt.% and 2 wt.%GA solution before applying the universal adhesive in self-etch and total-etch modes.They were randomly divided into six groups (n=10): 1) self-etch control, 2) total-etch control, 3) 1% GA + self-etch, 4) 2% GA + selfetch, 5) 1% GA + total-etch, and 6) 2% GA + total-etch.Teflon molds were fixed on the prepared dentin surface, and then the composite was inserted into the molds and light cured.After spending 24 hours in a storage condition with 100% humidity at room temperature, specimens underwent the SBS test.The SBS values calculated by the universal testing machine were analyzed using ANOVA and Tukey's post hoc tests (p < 0.05).Results: The application of 1% and 2% GA before using the universal adhesive revealed a significant increase in the mean SBS values compared to respective control groups (p < 0.001, p < 0.001), and the mean values for 1% GA were significantly higher than 2% GA in both etching strategies (p < 0.001, p < 0.001).The groups that utilized the universal adhesive with the total-etch method exhibited statistically higher SBS values than those using the selfetch approach, irrespective of applying GA and its concentration (p < 0.001).Conclusions: Applying 1% and 2% GA improved the shear bond strength of composite resin to the dentin in both self-etch and total-etch approaches with the universal adhesive.These findings indicate that GA holds great potential for expanded clinical applications.
