Outline of Research at the Start

本研究は、硬組織形成と炎症制御の両特性を備えた直接覆髄材として応用可能な材料の候補を、カルシウム感受性受容体への結合能の観点および組織修復能を有するM2マクロファージ誘導能の観点からスクリーニングするとともに、選択された材料の臨床応用の可能性について、動物実験モデルを用いてについて評価を行うことです。本研究より新しい直接覆髄材が開発され、その結果として歯髄をより効率的に保存することが可能になると期待されます。さらには、覆髄材以外に骨補填材等への応用が期待されます。

Outline of Final Research Achievements

We investigated the hard tissue induction ability of calcium silicate sealers, Bio-C sealer, Well-Root ST, and EndoSequence BC sealer. We revealed that they induced mineralized nodule formation of osteoblast-like cell line, Kusa-A1 cells in a calcium ion-dependent manner, They also promoted mRNA expression of osteopontin, one of the osteoblast markers. The same effect was also observed with a surface-reaction-type pre-reacted glass-ionomer (S-PRG) filler-containing sealer.

Academic Significance and Societal Importance of the Research Achievements

生体傷害性を示さないだけではなく、硬組織誘導能および炎症制御能といった生物活性を有する歯内療法で使用する様々な材料が近年注目を集めている。今回現在新しく歯内療法に導入されたBio-C sealer、Well-Root ST、EndoSequence BC sealerの硬組織誘導能および炎症抑制能について検討し、どれもが硬組織誘導能および炎症抑制能を示したことから臨床においても良好な成績を示すことが期待される。また試作surface-reaction-type pre-reacted glass-ionomer filler 含有シーラーにおいても抗炎症能が示され、臨床応用が期待される。
