Abstract: A viscous material container that makes it unlikely that air remains in a housing when a piston is inserted from an insertion port of the housing. A first section of the housing is formed with two groove portions communicating with a first passage to discharge air in the first passage when a piston is inserted from an insertion port. The two groove portions communicate with the insertion port, and extend along a first imaginary center line.

Abstract: Provided herein is a viscous material container that is not likely to form continuous streaks or asperities on the surface of a viscous material discharged from the viscous material container even if the viscous material is highly viscous. A third section of a housing includes a wall having a wall portion that is positioned radially outwardly of a continuous angular portion with respect to a second imaginary center line, and extends along the continuous angular portion. The wall portion is configured to expand radially outward when a dental viscous material pushed out from a discharge port.

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 R1 represents 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, R2 represents a substituent consisting of three or more carbons which may have an electron-withdrawing group, R3 represents 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.)-
