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/ml 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.
