Abstract
[Problem] To provide a dental photocurable composition which has sufficient mechanical property and whose rheological property is not deactivated even after long-term storage. [Solution] The dental photocurable composition of the present disclosure comprises (A) polymerizable monomer, (B) photosensitizer, (D) photopolymerization accelerator and (E) filler, wherein, the dental photocurable composition comprises (D1) aliphatic tertiary amine compound represented by formula (1) as the (D) photopolymerization accelerator, and the dental photocurable composition comprises (E1) hydrophobized silica fine particle having an average diameter of primary particle of 1 to 40 nm as the (E) filler. (wherein Rrepresents a substituent consisting of three or more carbons having an electron-withdrawing group at α-carbon and/or β-carbon of an amine starting from N, Rrepresents a substituent consisting of three or more carbons which may have an electron-withdrawing group, Rrepresents a substituent consisting of one or more carbons which may have an electron-withdrawing group, and α-carbon of N in the formula (1) is not an electron-withdrawing group.)
