To provide a dental curable composition which has an operation time within a reasonable range and is excellent in the adhesion to dentin and the mechanical strength of a cured material.SOLUTION: A dental curable composition contains a polymerizable monomer (A) having an acidic group, a polymerizable monomer (B) having no acidic group, a hydroperoxide (C), and a thiourea compound (D) represented by general formula (1). (In the formula, A1 and/or A5 are any of a hydroxy group, an alkoxy group, an amino group and a dialkylamino group; and A2 to A4 are each independently a hydrogen atom, a hydroxy group, an alkoxy group, an amino group, a dialkylamino group, a hydrocarbon group, a carboxy group, or a halogen atom.)SELECTED DRAWING: None 【課題】操作時間が適度な範囲内にあり、歯質に対する接着性、及び硬化物の機械的強度に優れる歯科用硬化性組成物を提供する。【解決手段】酸性基を有する重合性単量体（Ａ）、酸性基を有しない重合性単量体（Ｂ）、ヒドロペルオキシド（Ｃ）、及び一般式（１）で表されるチオ尿素化合物（Ｄ）を含有する歯科用硬化性組成物。TIFF2023056979000022.tif32170（式中、Ａ1及び／又はＡ5はヒドロキシ基、アルコキシ基、アミノ基、ジアルキルアミノ基のいずれかであり、Ａ2～Ａ4はそれぞれ独立して、水素原子、ヒドロキシ基、アルコキシ基、アミノ基、ジアルキルアミノ基、炭化水素基、カルボキシ基、又はハロゲン原子である。）【選択図】なし
