Abstract :
Aims: The effect of 10% sodium ascorbate and 5% proanthocyanidin on shear bond strength of composite resin to bleached enamel using 5th and 7th generations of bonding agents. Methods and Material: Eighty recently extracted maxillary central incisors were randomly divided into four groups of 20 teeth each. Except for group I(control), the labial surfaces of all other specimens were bleached with 38% hydrogen peroxide gel. Groups III and IV were treated with antioxidants 10% sodium ascorbate and 5% proanthocyanidin respectively for 10 min. All four groups were further subdivided into two subgroups of 10 teeth each depending upon the adhesive system used to bond the composite resin. Subgroup A and B were treated with 5th and 7th generation of bonding agent respectively. All the specimens were stored in deionized water for 24hours before testing the shear bond strength under universal testing machine. Results: The shear bond strength was maximum for the control group followed by the group which was treated with 5% proanthocyanidin solution. Subgroup A which was treated with 5th generation bonding agent resulted in higher shear bond strength than that obtained with Subgroup B. Conclusions: Within the limitations of this study it was observed that the shear bond strength was greatly increased on the use of antioxidants after bleaching. The shear bond strength on using 5th generation bonding agent was higher than that obtained with 7th generation bonding agent.
