Abstract

PURPOSE
The purpose of this study is to compare the antibacterial activity of currently purchasable denture cleansers against Candida albicans.
Materials and methods
This study used tablet-type denture cleansers, Polident , Coolingdent and Fittydent , along with liquid denture cleansers, Hexamedine , Listerine and Apple vinegar . The antibacterial activities of denture cleansers were evaluated based on the number of C. albicans and concentrations of the denture cleansers.
Results
In the 0.5 × 106 cfu/㎖ culture medium, the C. albicans’ death rate of Polident was significantly lower than those of Fittydent , Hexamedine , Listerine , and Apple vinegar (P <.05). In the 0.5 × 107 cfu/, the C. albicans’ death rates of Polident and Coolingdent were significantly lower than those of Fittydent , Hexamedine , Listerine and Apple vinegar (P <.05). The C. albicans’ death rates of Polident and Coolingdent were significantly decreased at 0.02 g and 0.01 g. The C. albicans’ death rate of Fittydent was significantly decreased at 0.005 g (P <.05). The C. albicans’ death rate of Hexamedine was significantly decreased at 1/16 dilution. The C. albicans’ death rate of Listerine was decreased at 1/8 dilution, and the antibacterial activity of Apple vinegar was decreased at 1/4 dilution (P<.05).
Conclusion
As the number of C. albicans increased, the antibacterial activities of the denture cleansers decrease. In the tablet-type denture cleanser, all denture cleansers showed 100% C. albicans’ death rate when used at a dose of 1 tablet. One denture cleanser showed the same antibacterial effect with only 1/3 of a tablet. In the liquid type denture cleanser, the level of dilution required was different for each denture cleanser.
