  "abstract": "Aim\n\nThe aim was to evaluate and compare the impact of applying quercetin, myricetin, and carvedilol after bleaching on the shear bond strength (SBS) of composite resin to enamel.Methods and materials\n\nIn this in vitro study, 50 intact single-rooted teeth were randomly allocated into five experimental groups as follows (n = 10): Group A (negative control): no bleaching, Group B (positive control): bleaching with 37.5% hydrogen peroxide, Group C: hydrogen peroxide ± 1% quercetin for 10 minutes, Group D: hydrogen peroxide ± 2.5% carvedilol for 10 minutes, and Group E: hydrogen peroxide ± 1% myricetin for 10 minutes. Bonding with resin composite was carried out without delay following bleaching for Groups B through E, whereas Group A underwent bonding without any prior treatment. Each specimen was assessed for SBS using a universal testing machine after being stored for 24 hours in distilled water kept at room temperature. Tukey's post hoc test and one-way analysis of variance were used to evaluate the SBS values for each group.Results\n\nThe unbleached group showed the greatest mean SBS for composite bonding, according to the data. Quercetin showed the lowest SBS among the antioxidant-treated groups; the carvedilol-treated group showed the highest SBS value, and the difference in SBS between the myricetin and carvedilol groups was not statistically significant.Conclusions\n\nIt was concluded from the data that a 10-minute application of 2.5% carvedilol improved the bond strength to bleached enamel, nearly restoring it to pre-bleaching levels.",
