A Comparative Study to Evaluate The Effectiveness of Two Commercially Available Disinfectants on Denture Base Acrylic Resin With an Organic Load
Background: The literature demonstrates that optimum disinfection can be obtained with the use of proper disinfectants for a proper period of time. Aim: To compare the efficacy of two disinfectants on denture base acrylic resin with an organic load. Materials and Methods: Seventy acrylic resin strips of size 48x2x8mm were made. Before each test the strips cleaned with chlorhexidine gluconate and two acrylic resin strips were selected and cultured for organism growth to ensure sterility. Six sterile acrylic resin strips were used for each disinfectant at each time. For each test two strips were used ( two for Staphylococcus Aureus, two for E.Coli and two for Candida Albicans) In each test one strip used as control group (normal saline). The data were analyzed statistically using one way ANOVA and Duncan Multiple Range Test. Results: Among two disinfectants 2% Glutaraldehyde achieved complete disinfection in 2 minutes for S. Aureus, E. Coli and C. Albicans. Conclusion: It is necessary to use denture disinfectants after removal and before insertion of denture for any adjustment.
