A 53-year-old woman with continuing pain coming from a lower first molar was diagnosed with apical periodontitis, with a retained fractured instrument in the root canal. There are a variety of treatment options for dealing with a corpus alienum in a root canal. In this case it was decided to treat the tooth endodontically, and leave the fractured instrument fragment in situ. The selection of this treatment option was made on the basis of knowledge of the original diagnosis and the success rates of the various treatment options as described in the relevant literature, weighed against the possible risks and their effects on the prognosis. This suggested that the use of a dental operating microscope has a positive impact on the success rates of endodontic treatment The prognosis for endodontic treatment when a fractured instrument fragment is left within the root canal, as in this case, is not significantly reduced. The presence of preoperative periapical pathology, however, is a more clinically significant prognostic indicator.
