Abstract
This study aims to present the management of a rare case of
a separated endodontic instrument in the periradicular area.
The broken instrument had penetrated within and along the
mandibular canal from the periapical zone of mandibular
second molar after endodontic treatment, leading to acute
neurological symptoms. These subsided completely following
surgical removal of the separated instrument. Because of the
close anatomic relation between the second molars and the
inferior alveolar nerve, careful clinical and radiographic
examinations should always be performed before endodontic
treatment of these teeth, so as to prevent iatrogenic injuries
of the type described here. Dentists should also be aware of
the anatomic characteristics of the mandibular canal (i.e.,
cribriform rather than solid), as well as the consequences of
overinstrumentation.
