Sunil Dogra, Trishika Dhiman, Gaurav Sepolia

Background: There are numerous products on the market with various claims for their efficacies in controlling or removing stain from the denture surface. Aim of the study: To compare NaOCl and sodium perborate in stains removal from acrylic resins.Materials and methods: The study was conducted in the Department of Prosthodontics of the dental institution. For the study, a set of 40 heat cured acrylic plates were formed. Each sample was then placed in reflectance spectrophotometer to record standard reflectance. Then, acrylic plates were stained with tea and turmeric by keeping them in tea and turmeric solutions for 30 minutes. The acrylic plates in Group 1 were cleaned with Sodium hypochlorite and plates in Group 2 were cleaned with Sodium Perborate. Then, the acrylic plates were placed in reflectance spectrometer to check the change in reflectance values. Results: We observed that mean change in reflectance in group 1 was 1.78 and in group 2 was 2.66. On comparing, the results were seen to be statistically non-significant. Visually, stain removal was more evident in Group 2 as compare to group 1. Conclusion:  From the results of the present study, this can be concluded that Sodium Hypochlorite and Sodium perborate are highly efficacious as a stain removal from acrylic resins. However, on comparing both, Sodium perborate is more efficacious.
Key words: Sodium Hypochlorite, Sodium Perborate, acrylic resin.
