Introduction: Contamination of resilient denture liner material with microorganisms, particularly Candida albicans, is a common clinical problem. Denture hygiene is essential to maintain the serviceability of the denture, and microwave has been suggested for denture disinfection. Aim: The aim of this study was to determine the effectivenes of microwave energy in the disinfection of a resilient denture liner contaminated with C. albicans. Material and methods: A resilient denture liner material was contaminated with Candida albicans and reduction of organism counts after test disinfection methods (microwave energy, soaking overnight in a dilute sodium hypochlorite and alkaline peroxide solutions) calculated. Results: In this study the effectiveness of microwave energy in the disinfection of resilient denture liners was determined. A one-way ANOVA test indicated that there was a significant difference between the groups. Conclusion: Disinfection of Vertex Soft resilient denture liner material in sodium hypochlorite solution proved a more effective method than exposure to microwave energy. Because sodium hypochlorite solution presents some disadvantages in clinical use, microwave energy disinfection can be considered an effective and simple alternative. Keywords: disinfection, resilient denture liner, microwave energy, candida albicans.
