Abstract: A method for brightening of teeth is described, using a kit with the components A an alkaline, aqueous sodium fluoride solution, containing a gel former, B a dried gel, present in film strips, containing B1 at least one gel former, B2 phosphate or hydrogen phosphate ions, B3 optionally at least one amino acid, B4 optionally fluoride, B5 optionally glycerol, B6 optionally a carboxylic acid or a buffer system for one of the pH values from 4 to 7. C a dried gel, present in film strips, containing C1 at least one gel former, C2 calcium ions, C3 optionally glycerol, as well as preparation of the kit.

Abstract: An agent for protection of tooth surfaces, in conjunction with conventional bleaching methods, by biomimetic deposition of fluorapatite, containing A at least one preformulated 50-1000 ?m thick gel film A, containing A1 at least one gel former, A2 water or a mixture of water and an organic solvent, A3 phosphate or hydrogen phosphate ions, A4 optionally fluoride, A5 optionally at least one amino acid, A6 optionally one carboxylic acid or a buffer system for a pH value from 4 to 7. B at least one 50 ?m to 5 mm thick gel film B, containing B1 at least one gel former, B2 water, B3 calcium ions Ca2+.

Abstract: Compositions for dental composites comprising monomers, crosslinking agents, fillers, initiators, A the proportion of crosslinking agent being formed in an amount of more than 50% by acrylate monomers with a TCD urethane structure having the general formula in which A, X, Z, R1 R2 R3 and r have the meaning indicated in claim 1, provide polymerized composite materials with a particularly low cytotoxicity according to the standard requirements according to ISO 10993-5 and DIN EN ISO 7405.

Abstract: The present invention relates to dental materials composed of calix[n]arenes and also to the use thereof for cements, composites, adhesives and coating materials in the dental field. The materials include (a) 0.5 to 90% by weight of at least one polymerizable calix[n]arene according to formula (I), (b) 0.01 to 5% by weight of initiator, (c) 0 to 90% by weight of at least one additional monomer which can polymerize under cationic and/or radical conditions and/or which can polymerize by ring opening, (d) 0 to 85% by weight of filler, (e) 0.01 to 5% by weight of additive and (f) 0 to 70% by weight of solvent.

Abstract: A two-component initiator system having accelerators for curing polymerizable materials comprising the following components: (a) a hydroperoxide compound containing one or more hydroperoxide groups that are bound to a tertiary carbon; (b) a thiourea derivative; and (c) as accelerator, a copper compound which is soluble in the preparation is preferably free of amine and is particularly suited for polymerizable dental compositions.
