| Outline of Final Research Achievements |
In endodontic treatment, removal of the infected tooth substance in the root canal is essential, but in consideration of the mechanical strength of the root after treatment, it should be minimized. Therefore, if it is possible to selectively remove infected tooth substance and contaminants in the root canal under visual recognition, the clinical prognosis after endodontic treatment is considered to be dramatically improved.
In this study, we developed an endoscope applicable to endodontic treatment and a jig to fix it to the teeth, and introduce a blue light with a wavelength of 405 nm as a light source. The experimental dental endoscope system could selectively remove the light emission site which indicated infected tooth substance and contaminants under monitoring the operative field.

歯内治療への内視鏡の応用は、これまで世界的にもほとんど報告がない。本研究では歯内治療に応用可能なシステムを開発しただけでなく、波長405nmの青色光によって感染した歯質や汚染物質などを健全歯質と識別しながら選択的に除去することに成功した。
