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.

本研究检测了含有光催化剂的组织调理剂对大肠杆菌的抗微生物/抗真菌能力。coli、S.金黄色葡萄球菌、mutans和C.白色念珠菌将含有光催化剂的粉末与液体混合以制备测试样品。用紫外光照射接种了每种微生物的试样0、2和4小时。通过CFU技术评价抗菌/抗真菌效果。含有光催化剂的组织调理剂的每种微生物的CFU值在UV照射后显示出显著降低。抗菌/抗真菌效果的改善是伴随着混合比和照射时间的增加。因此，结果表明，含有光催化剂的组织调理剂可能具有光催化能力。
