Abstract: The tool for extracting broken endodontic instrument has a cylindrical, tubular body. The body has a cap at one end and a conical nose at the opposite end. A gripper tube for gripping a broken endodontic file extends from the conical nose. The body of the tool houses a heating or soldering device equipped with a magazine of balls of solder. The gripper tube has an open tip dimensioned for slidably receiving an end of the broken file and resilient gripper prongs inside the tube allowing insertion of the end of the file but preventing the file from exiting the gripper tube. The heating device may be turned on to melt a ball of solder to solder the gripper prongs to the broken file to further secure the broken file to the gripper tube for extraction of the broken endodontic tube from the root canal.
