The Charisma of 3D Imaging in Managing Endodontic Mishaps in Calcified Canal: A Case Report

Abstract

Management of calcified canals is always challenging and is much more prone to mishaps such as perforations and ledge formations. The Two-dimensional (2D) imaging has a limitation, the 2D image of a Three-dimensional (3D) structure overlaps adjacent structures even over the root canals. This can create large confusion during treatment. Here, we are reporting a case where 2D imaging misled the treatment and 3D imaging evolved as a magical tool. A 32-year-old female, presented with complaints of pain, blackish discolouration and repeated sinus tract formation after her initial sitting of previous root canal treatment with upper right front tooth #11. On the radiograph, improper obturation and periapical radiolucency were evident. Hence, re-root canal treatment was advised and initiated. Gutta-percha was removed and radiographs were taken to ensure the removal of gutta-percha followed by working length estimation, which was satisfactory. After following all irrigation protocols, calcium hydroxide was placed as intracanal medicament but the patient came after two days with a draining pus sinus. The same happened with double antibiotic paste. Hence, Cone-beam Computed Tomography (CBCT) was advised. A buccal perforation and calcified unnegotiated canal were evident in all sections of CBCT. With the consent of the patient, the canal was again negotiated and guided with multiple angled radiographs. Intraoperative CBCT was advised with a master gutta-percha cone to verify the correct position of the canal. After verification, perforation was sealed with biodentine followed by obturation with crown placement in subsequent visits. Thus, 2D imaging can be misleading and 3D imaging is a guiding tool.
