Comparison of efficacy of sodium hypochlorite with sodium perborate in removal of stains from heat-cured clear acrylic resin.

Acrylic resin bases of removable dentures attract stains and odor-producing organic and inorganic deposits. The use of chemical denture cleanser soaks is the most popular method of denture cleansing. This study was undertaken to compare the efficacy of two different denture cleansers--sodium perborate (Clinsodent) and sodium hypochlorite (VI-Clean)--in removing tea, coffee, turmeric and tobacco (paan) stains from heat-cured clear acrylic resins. Distilled water was used as a control. Both Clinsodent and VI-Clean were found to be the least effective in removing coffee stains and best for removing turmeric stain. It is necessary that the dental professional be aware of these results to ensure that denture wearers know how to select the appropriate denture cleanser.
