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.
