Dr. Danish Zahoor | Dr. Ashish Gupta | Dr. Aashee Verma | Dr. Ashwani Dahiya

Abstract: Aim: This study was performed to evaluate the effect of an antioxidizing agent on the shear bond strength of bleached teeth. Materials and Methods: A total of 60 non carious, sound premolar, extracted for routine orthodontic treatment (Fig.1) were used in this study. The samples were divided randomly into three groups of 20 each as Group A, B and C. The acrylic blocks in which the teeth were embedded were color coded. Group A was the control group, whereas Group B and C were the study groups. Results: Maximum Shear bond strength was observed in Group A - (Control group, ethched and bonded, white coloured), which was 10.86 ? 2.05 Mpa, followed by Group C (treated with antioxidizing agent, bleached and bonded, pink coloured) which had the Shear bond strength of 6.38 ? 2.65 Mpa. Whereas Group B (bleached and bonded, purple coloured) had the Shear bond strength of 3.19 ? 0.68 Mpa. Conclusion: Bleaching with 35% hydrogen peroxide reduced the Shear bond strength.
