[A method for extracting broken endodontic instruments left in immediate proximity to the root canal opening]

In order to remove the fragment of an instrument, filling material evicrol is applied onto the mouth of the root canal in which the end part of the broken instrument is detectable; the second half of the endodontic instrument is introduced in evicrol substance. After evicrol hardening the two parts of the instrument are reliably connected, and thus the fragment may be removed from the root canal.
