The invention relates to a light-curing composition for producing dental components in a DLP method or SLA method, comprising, in relation to the total mass of the light-curing composition: a liquid monomer composition with a mass fraction of 60% or more, comprising one or more radically polymerizable monomers, one or more photoinitiators with a combined mass fraction in the range from 0.001 to 10%, and solid polymer particles with a particle diameter in the range from 0.4 to 4 μm and a combined mass fraction in the range from 0.1 to 30%, wherein the solid polymer particles are dispersed in the liquid monomer composition.

It is an object of the present invention to provide fine fibrous cellulose capable of enhancing transparency and suppressing coloring, when the fine fibrous cellulose are processed into a dispersed solution or a sheet. The present invention relates to fine fibrous cellulose, in which the amount of substituents introduced is less than 0.5 mmol/g and the fiber width is 1 to 10 nm. Moreover, the present invention relates to a dispersed solution and a sheet, each of which comprises fine fibrous cellulose. Furthermore, the present invention relates to a method for producing fine fibrous cellulose, comprising: (A) removing at least a part of substituents from fine fibrous cellulose with a fiber width of 1000 nm or less having the substituents, and (B) performing a uniform dispersion treatment on the resulting fine fibrous cellulose after completion of the (A).

A radically polymerizable composition having at least one acidic radically polymerizable monomer, at least one fluoroaluminosilicate glass filler and/or radiopaque glass filler, and at least one masking agent in solid form.

Provided is a dental curable composition containing: (A) a porous organic-inorganic composite filler which comprises an organic resin component obtained by polymerizing a polymerizable monomer component (a) including at least 50 mass % of a polymerizable monomer having a hydrogen-bonding functional group, and an inorganic component composed of a plurality of inorganic particles; (B) a polymerizable monomer component including at least 10 mass % of a polymerizable monomer having a hydrogen-bonding functional group; and (C) a polymerization initiator, wherein (C) the polymerization initiator comprises, as photopolymerization initiators, (c1) a photosensitizer compound, (c2) a reducing agent, and (c3) a photoacid generator composed of an aryliodonium salt compound, and the content of the aryliodonium salt compound is 0.1-5 parts by mass with respect to 100 parts by mass of the total mass of (B) the polymerizable monomer component.

Disclosed herein is a dental impression material that includes a two part addition curing silicone composition. The disclosed impression material contains a surfactant system composed of a fluorosurfactant and a fatty alcohol ethoxylate. The impression material disclosed herein exhibits improved storage stability than known systems using fluorosurfactants and silicone ether compounds.

A method of smoothing teeth by, for instance, filling in cracks, chips and eroded areas by applying calcium and/or casein and/or phosphate and a source of OH.sup.− ions thereto. The method optionally provides that very thin layer(s) of dental cement be interlaced with other applied materials, and that the results be maintained in contact with the teeth involved by application of a composition of matter that adheres to said teeth and holds the results in place, while allowing at least some permeation of saliva therethrough. The method can optionally involve application of a backing strip or tray or the like to secure the other materials in place, but this is not a requirement where the composition of matter is sufficiently securing.
