Background/Aim: Although there are studies about the antimicrobial activity of silver, there is no study evaluating it as a denture disinfectant. The purpose of this study was to explore the effectiveness of 6 disinfectant solutions (50% vinegar, 100% vinegar, 1% silver nitrate, 2% silver nitrate, %1 sodium hypochlorite, 0,12% chlorhexidine digluconate) in the disinfection of acrylic resin specimens contaminated in vitro by Candida albicans, as measured by residual colony-forming unit (CFU). Material and Methods: 66 pieces of 10mmx2mm acrylic resin disc samples were prepared and incubated in 1x106 cell/ml suspension of C. albicans ATCC 18804 for 24 h (one of them as a control, n=11/group). The specimens were then transferred into tubes containing 10 ml of the tested disinfectants and kept for 10 minutes in the disinfectant. After washing with saline, the specimens were vortexed to remove the microorganisms adhered to the surfaces. Colony counting of the collected microorganisms was performed on Sabouroud dextrose medium using 10-1, 10-2 and 10-3 dilutions. The results were analysed using Kruskal-Wallis and Mann-Whitney U tests (p<0,05). Results: The results showed that 1% sodium hypochlorite, %1 silver nitrate and 2% silver nitrate were the most effective against Candida Albicans (p<0,05), followed by 100% vinegar, 0,12% chlorhexidine digluconate and 50% vinegar (p<0,05). Conclusions: Within the boundaries of this study, we conclude that 1% silver nitrate is a promising alternative disinfectant to 1% sodium hypochlorite and performs better compared to 0,12 % chlorhexidine gluconate, 50% and 100% vinegar.
