| Outline of Final Research Achievements |
It has been reported that a titanium oxide nanotube (TNT) has a specific tube structure and diversity of the titanium crystals, as well as superior photocatalytic capacity and a physicochemical function. We did basic research on TNT. We measured its number of radicals and its changes in methylene-blue (MB) solution to evaluate its photocatalytic capacity. Also, we examined its effect on tooth whitening. We found that the TNT produced radicals such as TiO2, reduced the concentration of MB, and bleached stained apatite pellets when combined with a low concentration H2O2. And after bleaching it using the bleach which increased TNT because increase in TNT confirmed the effect on bleaching of tooth effect, a tendency to increase as we increased combination quantity of the TNT was found.
