Improved compositions for treating dental pulp and root canals comprising a mixture of particulate materials with water-based liquids containing polyvinyl pyrrolidone are provided. Homopolymers and copolymers of polyvinyl pyrrolidone can be used. Optionally, the composition may contain surfactants, humecatants, stabilizers, and other additives. Examples of particulate powders include mixtures of calcium silicate, calcium aluminate, calcium sulfate, and hydroxyapatite. The compositions are particularly suitable for sealing and obturating dental root canals and root apices. The composition provides a stable barrier to bacterial and fluid leakage in the root canal system of a tooth. |
