Abstract
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. To investigate the efficacy of rice vinegar and other disinfecting solutions in removing C. albicans from acrylic resins. Hundred and eighty acrylic resin plates were contaminated with C. albicans strains and divided into five 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 ANOVAwith Tukey post-test. Significance level of p< 0.05 was used. 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%). RV was as effective as ACV, WWV and CHX in removing C. albicans from acrylic plates at 8 hours.

Summary
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, accessible denture disinfectants. (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%). According to the World Health Organization, globally approximately 30% of people aged between 65 -74 years are edentulous,[1] with many replacing lost teeth with dentures. Denture hygiene remains the mainstay preventive measure in the management of denture-wearing patients.[2]
