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.

Abstract: Water-indicating endodontic monitoring devices include an endodontic cone formed of a water absorptive material, and a chemical indicator comprising at least one cobalt salt applied to the water absorptive material. Alternatively, the water-indicating endodontic points may include a pH-changing material and a pH-sensitive indicator. The devices are manufactured by applying an aqueous solution that includes a moisture sensitive color-changing chemical indicator to the endodontic cone. The solution may be applied by spraying, dipping, or otherwise coating or impregnating the material. Once applied, the endodontic cones are dried so as to be substantially free of moisture. In use, the endodontic cone may be inserted into the root canal of a patient, and when withdrawn, a change in the color of the chemical indicator indicates the presence of moisture within the root canal.
