Outline of Final Research Achievements

In this study, the conventional quantitative analysis of the trace elements was combined with the elemental distribution, chemical state, and micro structural analyses using the synchrotron X-ray and focused charged particle beams. Using those combined analyses, the characteristic elemental accumulations in the lesional hard and soft tissues were observed and the relations between the accumulated elements and lesions were suggested. The absorption behavior of the tooth for ions which released from the functional dental materials and ion doping agents was estimated with above methods. The chemical state and local structure of absorbed ions in tooth were also estimated. The obtained information was applied for the development of ion releasing endodontic materials.

Academic Significance and Societal Importance of the Research Achievements

口腔粘膜や呼吸器粘膜も多様な歯科修復材料や飲食物、吸入異物の影響を受けやすく、外来性の微量元素がこれら組織に及ぼす影響や、それに起因する病変の発症機序を明らかにすることは急務である。また歯質強化などを目的とした機能性歯科材料・薬剤も多く開発されており、それらの機能発揮の機構を明らかにするためにも微量元素の生体内挙動の解析は必須である。申請者らが開発した量子ビームを用いる微量元素解析手法は、生体試料を非損傷で、元素分布と化学状態情報を同時に取得し、組織学的情報と対比して検討でき、微量元素と生体の関連や各種歯科材料・薬剤の機能評価に繋げられると考えられる。
