![]() 2,3įractured endodontic instruments may include endodon-tic files, Gates-Glidden burs, lateral or finger spreaders or spiral fillers manufactured from stainless steel, NiTi or carbon steel. This further leads to micro-organisms penetrating the root canal system, indicating the development of a periapical lesion and treatment failure. It is noticed clinically that when an instrument fractures in a root canal system, it is often associated with incomplete root canal obturation, ineffective coronal seal or poor definitive restorations ( Figures 1 and 2). In the presence of periapical lesions, instrument fracture may reduce the chances of successful healing. The fracture of NiTi files during preparation may result in a compromised prognosis for the tooth. Despite the advent of NiTi files, the risk of fracture during the endodontic preparation of root canals, especially in severely curved canals, remains a serious concern. Instrument fracture is a serious complication during endodontic treatment of teeth, having an adverse effect on the outcome of the nickel titanium (NiTi) treatment, especially if the fracture prevents apical access to the infected root canal.
