Guided endodontic therapy: Management of pulp canal obliteration in the maxillary central incisor.

ABSTRACT

This is a case report of the management of pulp canal obliteration of maxillary central incisor using guided endodontic therapy. Patient reported with discolored and proclined 11. Intraoral periapical (IOPA) Radiographs and cone-beam computed tomography (CBCT) showed periapical radiolucency. The canal was obliterated till the middle third and was patent in the apical 7 mm. Root canal treatment (RCT) was planned using guided endodontics. Information of CBCT and digital surface scan were integrated using Blue Sky Bio software. A transparent three-dimensional (3D) model of the tooth and stent, designed with a sleeve for insertion of bur, was 3D-printed using clear resin. After orientation was found satisfactory on the 3D model, access opening was initiated with the orientation of round bur through the stent. IOPAs were taken after preparation of every 3 mm. The canal was located in the apical third. Cleaning and shaping were performed, and RCT completed successfully. Guided endodontic therapy is useful in the management of calcifications in anterior teeth.
