“…It has been reported that allowing a one-week period between bleaching and restorative treatment reversed the enamel bond strength [2]. However, this method was not effective for bleached dentin [23,27].…”

The purpose of this study was to evaluate the tensile bond strength to peroxide-exposed dentin. Furthermore, the effect of ascorbic acid on the bond strength of peroxide-exposed dentin was investigated. Extracted bovine dentin was exposed to 10% carbamide peroxide, 30% hydrogen peroxide or distilled water for 30 min, then treated with 10% ascorbic acid (0,30, 90, 180 min), and conditioned with 10% citric acid/3% ferric chloride. The PMMA rod was bonded to the treated bovine dentin with 4-META/MMA-TBB resin. A mini-dumbbell-shaped bonded specimen was prepared from these bonded assemblies and the tensile bond strength was tested. The fractured surfaces were also observed with SEM. Exposure to peroxide before bonding significantly reduced bond strength. The application of ascorbic acid to the peroxide-exposed dentin increased bond strength. On the other hand, an adverse effect of ascorbic acid was found in distilled water-affected dentin.Extended resin fibers were partially seen in the peroxide-exposed dentin. In conclusion, peroxide reduced the bond strength, and the stronger the oxidation, the weaker the obtained bond. Anti-oxidation with ascorbic acid recovered the bond strength, and the effect increased the longer the ascorbic acid was applied.

“…Similarly, removal of the superficial layer, pretreatment of bleached enamel with alcohol, and use of adhesives containing organic solvents have been also suggested to result in complete reversal of the reduced enamel bonds [16][17][18] . Recently used bonding agents can be divided in two groups by their surface conditioning method.…”

“…Time of application of ascorbic acid as reported in the literature ranges from 10min to 3 hrs to obtain satisfactory results. [3][4][5][6] A quest to look for an alternative anti-oxidant has led to a search of naturally available antioxidants such as green tea, grape seeds extract, pomegranate seed extract, and tomato seed extract, etc, which appear to have shown more efficient antioxidant property and also safer and economical. 7 Therefore newer naturally available antioxidants are being investigated as an alternative replacement to sodium ascorbate.…”

Background:With the minimal invasive concepts gaining popularity, vital tooth bleaching is well accepted treatment with predictable outcome. One of the disadvantages of tooth bleaching is decreased bond strength of composite resin to enamel. Antioxidants are used to get back the decreased bond strength. Aim of the study: was to investigate, the effect of immediate application of three anti-oxidant agents on reversal of decreased bond strength of composite resin to bleached enamel & to evaluate and compare the resin enamel interface with and without the use of antioxidants using SEM. Materials and Methods: Labial enamel surfaces of 50 extracted human maxillary central incisors were randomly divided into five groups based on the antioxidant used, Group I (n=10): negative control, Group II (n=10): positive control, Group III (n=10): bleaching followed by 10% sodium ascorbate solution application , Group IV (n=10): bleaching followed by 5% pomegranate seed extract application , Group V (n=10): bleaching followed by 5% tomato seed extract application. Each specimen was tested for shear bond strength. Two specimens from each group were selected for scanning electron microscopic (SEM) observation to assess resin enamel interface. Results: Significantly higher shear bond strength values were observed in Group IV, Group V as compared with the control groups, Group I and II. SEM analysis also proved the above results.
