Abstract
A dental material primer and a dentin-regenerating pulp-capping agent which exhibit an excellent dentin-regenerating action, are disclosed. The dental material primer includes a hydrolyzed ethylene-vinyl acetate copolymer in which collagen is immobilized and the dentin-regenerating pulp-capping agent includes a hydrolyzed ethylene-vinyl acetate copolymer, in which collagen is immobilized, and a binder.
Claims8
A dental material primer comprising a hydrolyzed ethylene-vinyl acetate copolymer in which collagen is immobilized, and a hydroxyl group-containing polymerizable monomer or an acidic group-containing polymerizable monomer as a primer component;
- wherein the hydrolyzed ethylene-vinyl acetate copolymer, in which collagen is immobilized, is fine particles having an average particle size of 0.2 μm to 30 μm;
- wherein the amount of the hydrolyzed ethylene-vinyl acetate copolymer, in which collagen is immobilized, is 1 to 50% by weight;
- and
- wherein the dental material primer contains a boron compound in an amount of 0.001 to 0.1 part by weight converted to boron content based on 100 parts by weight of the hydrolyzed ethylene-vinyl acetate copolymer, in which collagen is immobilized.
A dentin-regenerating pulp-capping agent comprising a hydrolyzed ethylene-vinyl acetate copolymer in which collagen is immobilized, and a binder;
- wherein the hydrolyzed ethylene-vinyl acetate copolymer, in which collagen is immobilized, is fine particles having an average particle size of 0.2 μm to 30 μm;
- and
- wherein the dentin-regenerating pulp-capping agent contains 1 to 100 parts by weight of the hydrolyzed ethylene-vinyl acetate copolymer, in which collagen is immobilized, based on 100 parts by weight of the binder, and contains a boron compound in an amount of 0.001 to 0.1 part by weight converted to boron content based on 100 parts by weight of the hydrolyzed ethylene-vinyl acetate copolymer, in which collagen immobilized.
