Abstract
Official abstract text for this publication.
Example embodiments of the present invention include compositions, materials, and methods that provide a single component tooth root sealer. The single component tooth root sealer can be designed to moisture cure at temperatures found within the human mouth. Examples of the single component tooth root sealer can include silicone compositions, such as condensation silicones of the alkoxy, acetoxy, and oxime type. Further examples of the single component tooth root sealer can include UV/visible light-initiators, antimicrobial agents, and radio-opaque compounds.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of sealing a tooth root after performing a root canal, comprising: obtaining a delivery device containing a single component tooth root sealer that is moisture curable, light curable, and in a ready-to-use state, the single component tooth root sealer comprising: between 50% and 90% alkoxy silicone composition; between 5%-10% anti-microbial agent; between 8%-20% radio-opaque compound; and between 0.5%-1.5% photo-initiator; expressing the single component tooth root sealer into the root canal; and exposing the expressed single component tooth root sealer to a visible light source and thereby light curing at least a portion of the expressed single component tooth root sealer. 2. The method recited in claim 1 , further comprising: allowing the single component tooth root sealer to moisture cure within the root canal. 3. The method recited in claim 1 , wherein the radio-opaque compound comprises barium oxychloride. 4. The method recited in claim 1 , wherein the anti-microbial agent comprises calcium hydroxide.
