Figure 8
Successful endodontic retreatment of 27 symptomatic, with broken instrument. (a) Preoperative X-ray of a patient sent for orthograde retreatment of 27, painful, with broken instrument (Lentulo) in the mesio-buccal root. The initial treatment was recent. (b) Peroperative X-ray: the broken instrument has been removed and apical patency was found before the cleaning, shaping, and filling of the canal. (c) Recall X-Ray with follow-up for 4 years. Note that lateral radiolucency had disappeared. The tooth is classified as “healed”: absence of symptoms and periodontal healing.
