Guided Endodontic Treatment of Calcified Lower Incisors: A Case Report
A 52-year-old female patient was diagnosed with chronic periapical periodontitis associated with severely calcified lower central incisors.
Radiographic examination revealed no visible root canal in the coronal-third of the root. After choosing the guided endodontic treatment, an intraoral scan (Trios, 3shape, Copenhagen, Denmark), in conjunction with a cone-beam computed tomography (CBCT) scan, was taken in order to design and fabricate a printed guide.
Virtual implant software was used to visualize the surgical access into the sclerosed root canals. After locating the canals, the guide was removed, and the teeth were treated under a rubber dam.
The guided approach allows predictable, efficient endodontic treatment of teeth presenting calcified canals, with minimal removal of sound dentine and less risk of root perforations.
