| Outline of Final Research Achievements |
The purpose of this study is to apply the nano photocatalyst to denture materials, and to acquire an antibacterial effect to improve the intraoral environment of the suffering elderly person at the time of the recent large-scale disaster. For the experiment, the sample piece which mixed 1-3% of titanium dioxide nanoparticles with normal temperature polymerization resin was made. And, under a condition of having light irradiation or not, the surface roughness examination, three points of bending tests, the antibacterial examination of Candida albicans were performed. As for the result, the significant difference was not recognized in the surface coarseness examination, three points of bending tests, the antibacterial examination in having light irradiation or not. By the experiment, the effective antibacterial action was not accepted, but the tendency to decrease of light Candida albicans of the irradiated nano photocatalyst component sample piece was just confirmed.
