Contracted Endodontic Cavity in a Severely Calcified Anterior Tooth Using Guided Endodontics Technique: Case Report

Abstract

Pulp canal obliteration (PCO) is characterized by the deposition of calcified tissue within the root canal space, which may partially or totally involve the canal. The endodontic treatment of calcified teeth is considered a challenging task depending on the severity of pulp obliteration. Recently, guided endodontics has become an alternative approach for those cases. This case report describes the use of guided endodontic access for the maxillary left lateral incisor of a 73-year-old male patient that required restorative treatment. The tooth had an extensive coronary fracture and demanded endodontic treatment for prosthetic purposes. Periapical radiography showed that pulp obliteration was severe at the cervical and middle thirds of the root. A cone beam computed tomography (CBCT) was requested in order to assess the level of obliteration. A three-dimensional (3D) template was planned with the CBCT's images along with intraoral scanning. A prototyped guide for guided endodontic access was performed, and the dental procedures were concluded safely. Guided endodontic access was paramount to overcome the pulp obliteration and ensured the endodontic treatment, and prosthetic rehabilitation could be performed.
