Abstract: The present invention relates to a dental etching composition comprising phosphoric acid, water and urethane-urea compound(s), to the use of said dental etching composition for etching the hard substance of the tooth, to a dental etching composition for use in a therapeutic method of etching the hard substance of the tooth in the course of filling treatment, and to a kit comprising a dental etching composition.

Abstract: The invention relates to a two-component dental elastomeric impression material with dimensional stability and storage durability based on addition curing silicone, wherein one component comprises a polymerization catalyst, containing or composed of a) at least one polydimethylsiloxane comprising polyatomic cross-linkable groups, preferably unsaturated cross-linkable groups, b) at least one polyaklysiloxane with Si—H functionalities, c) at least one catalyst for the reaction of a polydimethysiloxane, comprising polyatomic cross-linkable groups, with a polydimethylsiloxane comprising Si—H functionalities d) one or more fillers, e) a combination of release agents, comprising i) at least one alkyl-substituted polydimethylsiloxane, in which the alkyl chain is linear or branched, and/or at least a polydimethylsiloxane, in which the alkyl chain is linear or branched, and partially or completely halogenated, preferably fluorinated, and ii) at least one paraffin, and further relates to a dental mold, use, a dent

Abstract: A photopolymerizable dental composition for application to and for the isolation and protection of gums and/or teeth during dental treatment is described. The composition can include (a) one or more photopolymerizable monomers selected from the group consisting of acrylates and methacrylates, (b) one or more photoinitiators, preferably selected from the group consisting of alpha-diketones, benzoin alkyl ethers, thioxanthones, benzophenones, acyl phosphine oxides, acetophenones, ketals, titanocenes, borates and sensitizing dyes, and (c) one or more molecular weight regulators selected from the group consisting of compounds which can be reacted with a radical of a monomer of component (a) with abstraction of an H radical from the molecular weight regulator in the allyl position. Also disclosed are kits comprising such a composition, methods for producing a corresponding protective layer, methods for treating one or more teeth, and methods of using the compositions as a masking compound.

Abstract: A dual-curing, multi-component dental composition is described. The dental composition can include: (a) one or more photopolymerizable monomers selected from the group consisting of acrylates and methacrylates; (b) one or more photoinitiators, selected from the group consisting of alpha-diketones, benzoin alkyl ethers, thioxanthones, benzophenones, acylphosphinoxides, acetophenones, ketals, titanocenes, borates and sensitizing colorants; (c) one or more molecular weight regulators selected from the group consisting of compounds which can be converted with a radical of a monomer of component (a), wherein the conversion takes place by abstraction of an H-radical from the molecular weight regulator in the allyl position; (d) one or more polymerization inhibitors for increasing the storage stability of the composition; (e) one or more inorganic fillers; (f) one or more initiators for a chemical curing at ambient temperature, and if necessary one or more further additives.
