Comparative Evaluation of Herbal and Chemical Dentin Disinfectants on the Shear Bond Strength of Adhesive Restorative Systems: An in Vitro Study
Abstract: Aim: To evaluate and compare the effect of conventional chemical and herbal dentin disinfectants on the shear bond strength (SBS) of adhesive restorative systems. Materials and Methods: This in vitro study evaluated five groups: positive control, 2% chlorhexidine, hydrogen peroxide, ethanol extract of propolis (EEP), and 5% Triphala. Disinfectants were applied using a microbrush for 30 seconds, followed by rinsing and air drying. A dentin bonding agent was applied and light cured. Composite build-up was performed, and shear bond strength was tested using a universal testing machine at a crosshead speed of 0.5 mm/min. Statistical analysis was performed using one-way ANOVA and Tukey's post hoc test. Results: All groups showed a statistically significant difference (p < 0.001). The control group demonstrated the highest SBS (14.55 MPa), followed closely by Propolis (14.51 MPa). Hydrogen peroxide showed the lowest bond strength among the groups. Conclusion: All tested disinfectants reduced bond strength to varying extents. Propolis demonstrated bond strength comparable to control and may be considered a promising alternative. Chlorhexidine showed acceptable performance among chemical disinfectants.
