    Abstract: A single-paste, self-adhesive dental curable composition that has strong self-adhesion to biological hard tissues (such as enamel and dentin of teeth) and good color tone adaptability suitable for use for aesthetic restoration is provided. A dental curable composition contains: an inorganic particle (A) with an average grain size in the range of 0.1 to 50 μm; an inorganic particle (B) with an average grain size in the range of 0.1 to 50 μm; a polymerizable monomer (C); and a polymerization catalyst (D). The refractive index na of the inorganic particle (A) and the refractive index nb of the inorganic particle (B) meet the relationship of na>nb. A cured resin material (E), which is obtained by curing a polymerizable composition containing the polymerizable monomer (C) and the polymerization catalyst (D), has a refractive index ne that meets the relationship (1): 0≦|na−ne|

    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: A dental curable composition that allows easily identifying the presence of the dental curable composition in an oral cavity is provided. A dental visible-light curable composition contains a fluorescent substance that generates fluorescence when irradiated with visible light. The fluorescent substance is a compound of formula A3B2C3O12 containing Ce, absorbs visible light with a peak wavelength in a wavelength range of 380 to 500 nm, and generates fluorescence with a peak wavelength in a wavelength range of 550 to 780 nm. In formula A3B2C3O12, A, B, and C are a dodecahedral eight-coordinate Y element, an octahedral six-coordinate Al element, and a tetrahedral four-coordinate Al element, respectively.

    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: Provided is a nozzle mounting structure of a component container by which a nozzle configured to rotate between a first position and a second position may be mounted to a housing without the need for a high processing precision and a high assembly precision. A pair of shaft portions support a body with the nozzle unitarily formed therewith. The nozzle rotates between the first position and the second position. A curved convex surface provided on the body is pressed against a curved concave surface provided on a first bottom wall portion of a housing by a pressing force imparted from a support portion.
