Abstract
A dental composition comprising: a) about 1 to about 80% by weight of particulate material including: (i) calcium silicate, calcium aluminate, tetracalcium aluminoferrite, calcium phosphate, calcium sulfate, silica, alumina, calcium oxide, calcium hydroxide, or mixtures thereof; wherein the particulate material has an average particle size of less than 40 microns; and b) about 1 to about 50% by weight liquid carrier including: (i) water-soluble polymer, and (ii) water.
Claims35
A dental composition comprising:
- a) about 1 to about 80% by weight of particulate material including:
- (i) calcium silicate, calcium aluminate, tetracalcium aluminoferrite, calcium phosphate, calcium sulfate, silica, alumina, calcium oxide, calcium hydroxide, or mixtures thereof;
- wherein the particulate material has an average particle size of less than 40 microns;
- and
- b) about 1 to about 50% by weight liquid carrier including:
- (i) water-soluble polymer, and
- (ii) water.
A method of treating a root canal in a tooth, comprising the steps of:
- a) preparing the root canal in the tooth to be treated,
- b) providing a composition comprising:
- (i) a mixture of about 1% to about 80% by weight of particulate material including calcium silicate, calcium aluminate, tetracalcium aluminoferrite, calcium phosphate, calcium sulfate, silica, alumina, calcium oxide, calcium hydroxide and mixtures thereof, wherein the mixture has an average particle size of less than 40 microns;
- and
- (ii) about 1% to about 80% by weight of a liquid carrier including:
- (1) water-soluble polymer;
- and
- (2) water;
- and
- c) introducing the composition into the tooth from coronal or apical openings.
A dental composition comprising:
- a) about 1 to about 80% by weight of particulate material including:
- (i) dicalcium silicate;
- tricalcium silicate;
- calcium sulfate dehydrate;
- a carbonate;
- calcium sulfate;
- a phosphate;
- and tricalcium aluminate;
- and
- wherein the particulate material has an average particle size of less than 15 microns.
The dental composition of claim 35, wherein the water-soluble polymer is selected from the group consisting of polyvinyl alcohols, polyvinyl-pyrrolidone (PVP), partially hydrolyzed polyvinyl acetates, (PVAc), polyacrylic acid (PAA), and polymethacrylic acid (PMA), hyaluronic acid, water-soluble poly-saccharides, poly amino-acids, and mixtures thereof.
