Outline of Final Research Achievements

Basic research on dental cements with ionic liquids was conducted. This cement can reduce the bond strength by a weak electric current. The effect of ionic liquid addition on cytotoxicity was investigated, and cell viability increased depending on the conditions. The data suggest that bubble generation and corrosion at the bonding interface are related to the mechanism of bond strength reduction by electric current.

Academic Significance and Societal Importance of the Research Achievements

歯科用セメントに関する学術研究はそのほとんどが「接着」に着目しているが，本研究では歯科臨床で必要とされるスマートな「除去」に焦点を当てたものであり，学術的独自性は高い。今回得られた成果により，本セメントの生体親和性や接着強さ低下のメカニズムについて良好なデータが得られており，将来的な歯科臨床での応用に向けて前進したと言える。
