| Outline of Final Research Achievements |
Endodontics treats narrow root canals that are surrounded by hard tissue and difficult to see directly, and it is important to understand the three-dimensional positional relationship of the medullary cavity that extends inside the tooth. In this study, we used a surgical microscope camera with 4K (3840x2160) resolution to achieve alignment with a three-dimensional image virtually constructed on a computer-based on the patient's CT image. We evaluated the three-dimensional identification accuracy and processing speed and verified the future potential and problems as a precision root canal treatment support system.

| Academic Significance and Societal Importance of the Research Achievements |
新しい歯内療法学の展開には、最先端の情報学、ロボット工学、バイオなどの学際的な基盤技術体系を構築することが必要であると思われる。歯内療法学の分野にコンピュータビジョンや拡張現実などの最新のテクノロジーを導入することによって生まれる新たな技術は、歯内療法の新たな展開という観点からも重要と考えられる。立体映像により複雑な根管形態を誰にでも容易に把握することが可能となり、より確実な診断と治療が可能となる。低侵襲治療を大きく変貌させる可能性が高く、得られた成果は極めて広範な疾患の治療に有用なものとなる。
