PROBLEM TO BE SOLVED: To provide a dental curable composition excellent in removability when an excess paste protruding from a margin part in adhering dentine to restoration substance for a tooth crown is removed in a semi-cured state by provisional irradiation with a light irradiator for a short time of 1 to 2 seconds, and excellent in mechanical characteristics just after the irradiation and 1 day thereafter.SOLUTION: A dental curable composition comprises a polymerizable monomer (a) having no acidic group, a photoinitiator (b), a polymerization promoter (c) and a filler (d), where the photoinitiator (b) comprises a triazine-based compound (b-1) substituted by 0.005 to 0.3 pt.wt. of a trihalomethyl group relative to the total amount 100 pts.wt. of the polymerizable monomer component, 0.001 to 0.3 pt.wt. of a α-diketone compound (b-2) and 0.001 to 3 pts.wt. of an aromatic amine compound (b-3) and where the polymerization promoter (c) comprises an aromatic sulfinic acid salt (c-1), a copper compound (c-2) and a benzotriazole compound and/or benzimidazole compound (c-3). |
