Results showed antioxidant treatment with 10% ��-tocopherol solution was the only effective agent to revert the oxidizing effects of the bleaching treatment on enamel [18]. Other studies evaluated and compared composite bond strength to carbamide peroxide bleached enamel following the application of 10% and 25% sodium ascorbate and alpha-tocopherol solutions. [https://en.wikipedia.org/wiki/Glafenine Glafenine] Result showed 10 min application of 10% and 25% sodium ascorbate and 25% alpha tocopherol solutions significantly improves the shear bond strength of composite resin to enamel [19]. Alpha tocopherol allowed free-radical polymerization of the adhesive resin to proceed without premature termination by restoring the altered redox potential of the oxidized bonding substrate and improve resin bonding [18,20]. Proanthocyanidin (Grape Seed Extract) Oligomeric proanthocyanidin complexes (OPCs) are primarily known for their antioxidant activity. However, these compounds have also been reported to demonstrate anti-bacterial, anti-viral, anti-carcinogenic, anti-inflammatory, anti-allergic, and vasodilatory actions [21]. Manimaran et al., studied the application of proanthocyanidin agent (PA) that improves the bond strength of root dentin treated with sodium hypochlorite (NaOCl). The results demonstrated that 5.25% NaOCl caused significant reduction (p (PA) agents. Higher ��TBS were observed for 6.5% grape seed extract (GSE) immediately (SB- 62.9MPa; OS- 51.9MPa) when compared to 6.5% cocoa seed extract ethanol-water(CSE-ET) (SB- 56.95MPa; OS- 60.28MPa), 6.5% cocoa seed extract acetone-water(CSE-AC) (SB- 49.97MPa; OS- 54.44MPa), and distilled water (CO) (SB- 52.0MPa; OS- 44.0MPa). GSE and CSE-ET agents provided enhanced immediate adhesion and stabilization to demineralized dentin after long-term storage, depending on adhesive system [24]. Ascorbate L-ascorbic acid (AA) is the white to light-yellow, water-soluble vitamin commonly known as vitamin C [25]. Sodium ascorbate (SA) is a salt of AA. Both AA and SA have antioxidant properties [26].
