a) Hydrogen peroxides
b) Detergents
c) Sodium perborates
d) Alkaline compounds
The correct answer is C. Sodium Perborates
All the denture cleansing powder and tablets contain detergent, flavouring agent, alkaline compounds and sodium perborat e. The main component is sodium perborate. It decomposes in water to form a peroxide solution which inturn breaks down to liberate oxygen. It is this oxygen bubbles that remove the debris on the denture surfaces.
