Methods of treatment of the dental pulp and filling root canals using water-based material

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;
• and
• (ii) about 1% to about 80% by weight of a liquid carrier including:
• (1) water-soluble polymer;
• (2) surfactant, the surfactant is selected from the group consisting of alkyl sulfates, alkyl ether sulfates, sarcosinates, and mixtures thereof;
• and
• (3) water;
• and
• wherein the ratio of the surfactant to the water-soluble polymer being no greater than 6 to 1;
• and
• wherein the mixture, the liquid carrier, or both further include a humectant, a hydroxyapatite, or both a humectant and a hydroxyapatite;
• c) introducing the composition into the tooth from coronal or apical openings and allowing the composition to harden.
