Abstract |
The authors report the case of a 43-year-old woman who underwent endodontic treatment of the right second mandibular molar with substantial extrusion of endodontic material into the mandibular canal. The patient presented at the Department of Oral and Maxillofacial Surgery with a persistent total anaesthesia of the lower lip and chin after two months. 2D panoramic view and 3D CT-scan examination highlighted the overfilling into the mandibular canal with a more than 50% stenosis of the canal and a consequently significant compression of the dental pedicle. A surgical decompression of the inferior alveolar nerve was performed through an inferior vestibular approach, using PiezoSurgery®. The tooth was conserved. After a period of 8days, paraesthesia of the lower lip and chin appeared. Thermoalgic sensitivity was recovered at 1month. At 3months postoperatively, the patient had recovered protopathic and epicritic sensitivity. Dental prosthetic rehabilitation was finally achieved one year postoperatively. The authors discuss the physiopathology of nervous injuries during dental procedures, and further strategies in the case of persistent neurologic disorders.
