PURPOSE: This study analyzed the influence of 10% sodium ascorbate (SA) on tag formation in bleached enamel. MATERIALS AND METHODS: Five groups were tested: G1 - control; G2 - bleaching with 10% carbamide peroxide (CP) + restoration; G3 - CP + SA + restoration; G4 - bleaching with 35% hydrogen peroxide (HP) + restoration; and G5 - HP + SA + restoration. The teeth were sectioned and decalcified, and the resin tags were analyzed at 400X magnification using an optical light microscope and Axiovision software. RESULTS: The resin tag lengths in µm for each group were as follows: G1 - 36.1A; G2 - 5.8C; G3 - 14.4B; G4 - 1.7D; G5 - 6.5C. Different letters indicate statistically significant differences. CONCLUSION: Tooth bleaching with CP or HP impairs the formation of resin tags, and the utilization of sodium ascorbate increases tags length.
