In vitro comparison of the effects of microwave irradiation and chemical and mechanical methods on the disinfection of complete dentures contaminated with Candida albicans

摘要: Background: Dentures can be a source of infection or cross‑contamination with microorganisms like Candida albicans. The aim this in vitro study was to compare the effects microwave irradiation, chemical techniques, and mechanical method (i.e., brushing) on disinfection complete dentures contaminated C. Materials Methods: In experimental study, sixty sterilized were divided into six groups 10 each. Groups 1 6 served as negative positive controls, respectively. (Groups 2–5) albicans subjected four procedures: Corega tablets, 2% glutaraldehyde, brushing, irradiation. Replicate aliquots (25 mL) suspension cultured Sabouraud dextrose broth. colonies counted after 48 h incubation at 37°C. To confirm long‑term disinfection, Trypticase soy broth (TSB) containers stored 37°C for 7 days, turbidity visually observed. Data analyzed one‑way ANOVA independent‑samples t‑test SPSS level statistical significance set 0.05. Results: disinfected irradiation (650 W, 3 min) glutaraldehyde (2%, exhibited no evidence fungal growth also TSB days incubation. However, using tablets that significantly more than two other methods (P = 0.000) less control group 0.000). differences between cleaning cleansing tablet not significant 0.017). Conclusion: Base results completely short term long term. Key Words: albicans, dentures,
