PROBLEM TO BE SOLVED: To provide a dental composition capable of more effectively inducing a hard tissue by imparting excellent handleability, mechanical properties, and adhesiveness and sealing property by an adhesion promoting monomer into a Portland cement component which is supposed to have ability of inducing a hard tissue.SOLUTION: The dental composition comprises (A) a compound having at least one polymerizable group in the molecule, (B) a filler, (C) a polymerization initiator and (D) a Portland cement component. The composition contains, with respect to 100 pts.wt of the dental curable composition obtained by mixing the above components (A) to (D), 10 to 85 pts.wt of the component (A), 15 to 90 pts.wt of the component (B), 0.01 to 40 pts.wt of the component (C) and 0.1 to 300 pts.wt of the component (D). By the dental composition, the dental composition which is supposed to have the ability of inducing a hard tissue also exhibits excellent handleability and physical properties and excellent dental adhesiveness.COPYRIGHT: (C)2012,JPO&INPIT【解決手段】本発明の歯科用組成物は、(A)分子内に少なくとも1つの重合性基を有する化合物、(B)フィラー、(C)重合開始剤、(D)ポルトランドセメント成分からなり、上記の(A)~(D)を混合して得られる歯科用硬化組成物の合計を100重量部としたとき、(A)成分を10~85重量部、(B)成分を15~90重量部、(C)成分を0.01~40重量部、(D)成分を0.1~300重量部の量の範囲内の量で含有されている。【効果】本発明の歯科用組成物によれば、硬組織誘導能を有するとされる歯科用組成物が優れた操作性と物性及び、優れた歯質接着性を備えた形態で提供できる。【選択図】なし
