Fracture of nickel-titanium (NiTi) endodontic files is an uncommon but potentially damaging occurrence during root canal preparation. If the broken portion of the file remains inside the tooth canal it can prevent complete preparation of the root canal with consequent negative impact on treatment outcomes. Removal of file fragment from the tooth canal is currently a mechanical process, which due to the limited working space and restricted view can lead to further problems including perforation of the tooth. Electrochemical dissolution is a relatively new method proposed to dissolve a fractured instrument, fully or partially within the canal, to enable its removal. In this article we explore the eﬀects of electrochemical dissolution on the root canal environment using high contrast time delay integration (TDI) X-ray micro-tomography (XMT) designed specifically for dental research.
