| Outline of Final Research Achievements |
The purpose of this study was to evaluate the image quality of dental panoramic radiographs and tomosynthesis corrections for a dental head phantom using both subjective and objective assessments, and to investigate the usefulness of these methods in dental clinical practice.
We demonstrated that tomosynthesis correction improves the diagnostic level for both anterior and posterior teeth when images are taken with a significant anterior displacement.
This study is the first report to examine the impact and usefulness of tomosynthesis on diagnostic levels for major features of teeth and periodontal tissues when panoramic X-rays are taken with displacement.

| Academic Significance and Societal Importance of the Research Achievements |
近年，ウイルスによる感染症が世界的な社会問題となっている．飛沫感染の感染防止対策は歯科医療関係者において重要な問題である．トモシンセシス法ではパノラマX線装置を用い口腔内に検出器を入れることなく撮影可能であるため，画像診断における感染防止対策の一助を担うことができると考えられる．
また，我が国は超高齢社会を迎え，車いす利用者など姿勢を保つことが難しい患者がさらに増え，従来の撮影法では診断が困難な場合が予想される.本研究で得られた結果は，ある程度の位置ズレならばトモシンセシス法を用いて画像補正を行う事で，診断レベルを担保できる可能性が示唆された．
