Abstract:
Background: The mesio-buccal roots of first molars in the maxilla typically contain MB2 canals, which are a sign of a very complex root canal system. Since periapical (PA) radiographs are a 2D radiographic modality and are frequently used to evaluate root canal morphology, they are unable to adequately visualise the presence of extra canals, such as MB2, resulting in incomplete treatment and continued symptoms of pulpal infection even after root canal therapy.
Aim: The aim of this study was to investigate the occurrence and location of Second Mesio-buccal Canal in Permanent Maxillary First Molars Cone Beam Computed Tomography Images of Patients Attending Dental Clinics in Thane District.
Material and Methods: 100 patients were examined using a retrospective radiography analysis. They underwent CBCT scans using a Kodak CS 9300 digital imaging equipment. Each CBCT scan was evaluated using Carestream software. With excellent resolution and precision, cone beam computed tomography (CBCT) imaging is a non-invasive medical image capturing technique that can also lessen superposition and distortion of neighbouring anatomical structures while showing the internal structures of the teeth in three dimensions. Due to its short scan periods and low radiation exposure, it can be used for clinical applications and in vivo dental anatomy studies.
Results: The occurrence of MB2 canals observed in maxillary first molars has significantly grown in recent years with the aid of CBCT imaging and dental operating microscopes. Overall, 37% of maxillary first molars had an MB2 canal. Only 3 (8.1%) of the 37 MB2 canals possessed the Vertucci Type IV configuration, compared to 34 (91.9%) of the 37 MB2 canals.
