The practice of endodontics, while not as common as today, was performed during the WWII era. Some of the materials used to fill canals during this time period include gutta-percha, calcium hydroxide, gold foil, and silver points. In this case study, fissures and fractures were present on the exposed root surfaces of the dental remains. Radiographs of the dental remains revealed canal systems similar to those obturated with a paste or semi-solid material. The root surface defects appear to be the access point for the radiopaque material...
