Abstract: An endodontic obturator for obturating a root canal includes a wire made of a conductive material, a carrier, and a sheath. The carrier is configured to releasably couple to the wire and is made of a first thermoset material. The sheath is configured to slidably receive the carrier and is made of a second thermoset material. The melting temperature of the second thermoset material is lower than the melting temperature of the first thermoset material. A method of obturating a root canal includes positioning the endodontic obturator in the root canal, ensuring the endodontic obturator is in a proper position by locating an apex of the root canal using the wire, sealing an apex of the root canal with the sheath, and removing the wire from the obturator.
