Abstract
An adhesive endodontic cone is chemically compatible with endodontic sealant resins, including hydrophilic resins used for sealing a root canal chamber. The adhesive endodontic cone comprises a hydrophobic elastomer substrate that is sized and shaped so as to be at least partially insertable into an exposed root canal of a tooth. The cone includes an adhesive attached to at least a portion of a surface of the cone so as to render the cone more chemically compatible with a hydrophilic endodontic resin. The adhesive includes a hydrophobic portion that is chemically compatible with the hydrophobic elastomer substrate and a hydrophilic portion that is chemically compatible with a hydrophilic resin.

An adhesive endodontic cone for placement into a root canal containing an endodontic sealant resin, the adhesive endodontic cone comprising:
- an endodontic cone comprising a hydrophobic elastomer and that is sized and shaped so as to be at least partially insertable into an exposed root canal of a tooth;
- and
- an adhesive attached to at least a portion of a surface of the endodontic cone so as to render the endodontic cone more chemically compatible with a hydrophilic endodontic resin.
An adhesive endodontic cone for placement into a root canal containing an endodontic sealant resin, the adhesive endodontic cone comprising:
- an endodontic cone comprising a hydrophobic elastomer and that is sized and shaped so as to be at least partially insertable into an exposed root canal of a tooth;
- and
- an adhesive attached to at least a portion of a surface of the endodontic cone so as to render the endodontic cone more chemically compatible with a hydrophilic endodontic resin, the adhesive coating on the endodontic cone substrate formed by:
- applying a curable adhesive composition to at least a portion of the surface of the endodontic cone substrate;
- and
- at least partially curing the curable adhesive composition so that it chemically adheres to the hydrophobic elastomer of the endodontic cone.
A method of filling and sealing a root canal in a tooth, comprising:
- (a) preparing a root canal during an endodontic procedure;
- (b) inserting at least one endodontic cone into the prepared root canal, at least a portion of the endodontic cone having a surface that is hydrophilic so as to be compatible with a hydrophilic endodontic resin;
- and
- (c) introducing an endodontic filling and sealing composition into the prepared root canal.
