Abstract
The invention relates to a dental composition for use as a dental retraction material comprising filler(s), paste forming liquid(s) and guanidinyl-containing polymer(s). The dental composition is typically stored in a capsule with a thin nozzle enabling the delivery of the material in the sulcus of a tooth.
Claims14
A dental retraction composition comprising:
- phyllosilicate filler(s),
- paste forming liquid(s),
- guanidinyl-containing polymer(s) derived from one or more amino-containing polymer selected from a polyvinylamine, a poly(N-methylvinylamine), a polyallylamine, a polyallylmethylamine, a polydiallylamine, a poly(4-aminomethylstyrene), a poly(4-aminostyrene), a poly(acrylamide-co-methylaminopropylacrylamide), a poly(acrylamide-co-aminoethylmethacrylate), a polyethylenimine, a polypropylenimine, a polylysine, a polyaminoamide, polydimethylamine-epichlorohydrin-ethylenediamine, a polyaminosiloxane, a dendrimer formed from a polyamidoamine and a polypropylenimine, a polyacrylamide, and an amino-containing polyacrylate,
- wherein the dental composition is characterized by a flow resistance greater than or equal to 8N.
