| Research Abstract |
This study examined the antimicrobial/antifungal ability of a tissue conditioner containing a photocatalyst for E. coli, S. aureus, S. mutans and C. albicans. Powders containing a photocatalyst were mixed with liquid to make test spsecimens. Test specimens inoculated by each microorganism were irradiated by ultraviolet light for 0-, 2-and 4 hours. The antimicrobial/antifungal effects were evaluated by the CFU technique. The CFU values of each microorganism for tissue conditioners containing a photocatalyst showed significant decrease following UV-irradiation. The improvement on antimicrobial/antifungal effects was concomitant with the increase of the mixing ratio and the irradiation time. Therefore, the results indicated that tissue conditioners containing a photocatalyst might have photocatalytic ability.
