| Outline of Final Research Achievements |
Through this study, it has been demonstrated that ultrasonic microscopy can objectively observe teeth non-invasively and without staining by utilizing acoustic impedance values. Furthermore, it has been shown that it can accurately depict lesions such as dental caries. Consistency in the evaluation based on acoustic impedance values was confirmed through control experiments. Additionally, the development of a portable ultrasonic microscope allowed for accurate assessments during tooth observations, suggesting the potential of chairside use for the evaluation of dental caries.

| Academic Significance and Societal Importance of the Research Achievements |
現在、歯科領域において診断を行う際、視診、触診、X線撮影検査などといった術者の主観的評価により診断をすることが一般的であるが、術者によらず客観的な判断により診断を行うことができれば術者にとっても、患者にとっても有益となる。今回用いた超音波顕微鏡は非侵襲かつ非染色で観察対象の客観的評価を行うことが可能であるが歯牙のような硬組織には用いられてこなかった。しかし今回の研究成果により、超音波顕微鏡が臨床応用可能であることがより強固に示されたため、歯科診断領域において大きな役割を担う可能性が示唆された。
