Introduction: Objective: To assess the antioxidant property of 10% amla extract in reversing the compromised bond strength and to assess the antioxidant property of 10% amla extract and Elsenz on the color stability of power bleached teeth. Materials and Methods: Ninty extracted single-rooted maxillary anterior were collected and divided as follows: The labial surfaces of 30 samples were subjected to power bleaching after which the samples were divided into three groups– Group I (control), Group II (antioxidant amla), and Group III (Elsenz) with n = 10 in each which were then stained with a coffee solution for 10 mins. The color difference was recorded with a colorimeter at baseline, after bleaching, after 7, and after 15 days of staining. sixty specimens were randomly divided into six groups (n = 10) as following: Group I (immediate bonding); Group II (bleaching + immediate bonding); Group III (bleaching + antioxidant and immediate bonding); Group IV (bleaching + 1 week storage + antioxidant + bonding); Group V (bleaching + 2 week storage + antioxidant + bonding); Group VI (bleaching + 2 week storage + bonding). All the specimens were tested for shear bond strength in universal testing machine. Statistical analysis was performed using ANOVA and Scheffe's post hoc test. Results:
  • Significantly higher staining was observed in Group II (amla) and least with Elsenz paste
  • The highest mean shear bond strength was found in Group I followed by Group V.
Conclusion: Elsenz showed the least staining followed by artificial saliva. 10% Amla extract neither was effective in preventing staining of power bleached enamel nor in restoring the poor bond strength of power bleached enamel.
