INTRODUCTION: Denture stomatitis, mainly caused by Candida albicans, often affect denture wearers. To manage these patients, denture hygiene is of utmost importance. There is a need for low cost, easily accessible denture disinfectants AIMS: To investigate the efficacy of rice vinegar and other disinfecting solutions in removing C. albicans from acrylic resins MATERIALS AND METHODS: Hundred and eighty acrylic resin plates were contaminated with C. albicans strains and divided into Ave groups. These were immersed in apple cider vinegar (ACV), white wine vinegar (WWV), rice vinegar (RV), chlorhexidine (CHX), and sterile distilled H2O (control). The plates were incubated at room temperature for 30 minutes, 1 hour and 8 hours. Candida removing ability of the disinfecting solutions was evaluated, and data was analyzed using two-way ANOVA with Tukey post-test. Significance level of p<0.05 was used. RESULTS: RV, ACV, WWV and CHX showed the highest efficacy (100%) in removing both C. albicans strains at 8 hours (p>0.05). CHX was the most effective disinfectant in removing both C. albicans strains at 30 minutes, 1 hour, and 8 hours (99%-100%). CONCLUSION: RV was as effective as ACV, WWV and CHX in removing C. albicans from acrylic plates at 8 hours.
