Outline of Research at the Start

本研究では、抗菌材としてAgを用いるにもかかわらず、変色しないリン酸カルシウムセメント系
覆髄材の創製を最終目的とする。歯内治療時における裏層・覆髄処置においては感染及び、これから派生する二次う蝕、感染巣の形成、口腔状態の悪化に起因する全身状態の悪化の改善は社会的な課題である。Ag本来の持つ優れた抗菌性を発揮しつつ、Agイオンの溶出に起因する変色の門問題を解決する。

Outline of Final Research Achievements

Since the introduction of biomaterials, infection has been a serious problem in clinical operations. Ag-substituted octacalcium phosphate (OCP) blocks exhibiting contact antibacterial ability were fabricated from precursor dicalcium dihydrate anhydrate blocks via immersion in both Ag+- and Na+ containing ammonium phosphate weak basic buffer solutions. Although the Ag contents of the Ag-substituted OCP blocks (0.17 ± 0.01 at%) were much lower than those of Ag-substituted OCP powders (1.72 ± 0.18 at%) prepared using Ag solutions with the same Ag concentration (20 mmol/L), the Ag-substituted OCP blocks exhibited excellent contact antibacterial activities toward various
pathogens. In vivo implanting in bone defects evaluations indicated that the biocompatibility of the Ag-substituted OCP blocks was excellent and similar to that of the OCP blocks without Ag.

Academic Significance and Societal Importance of the Research Achievements

本研究では、抗菌材としてAgを用いるにもかかわらず、変色しないリン酸カルシウム材料の創製を最終目的とし、研究を行った。歯科・整形外科において、骨再建・再生時の術後感染は深刻なリスクである。特に、骨補填材由来の感染は、深刻化しやすい。抗菌元素であるAgを骨補填材に強固に含有させることで、術後感染を予防し、かつ高い骨再生能を発揮する材料の開発を目指したものである。
