Abstract
A cartridge includes a chamber structure configured to contain endodontic material. An electrically conductive heating layer is provided adjacent to the chamber structure. A first electrode is positioned at one side of the cartridge, with the first electrode being in electrical contact with the heating layer, and a second electrode is positioned at a second side of the cartridge, with the second electrode being in electrical contact with the heating layer. An outer sleeve encases the chamber structure, the heating layer, and the electrodes, with an air gap being formed between the outer sleeve and the heating layer.
