Evaluation of the Root canal configuration of left mandibular first molars using Cone Beam Computed Tomography (CBCT). Materials And Methods: 95 Patients attending the OPD of Oral Medicine and Radiology Department of K.D. Dental College and hospital, Mathura were recruited in the study. Study subjects comprised of patients having carious lesions in the left permanent mandibular first molar and requiring endodontic treatment. The written consent was obtained from all the subjects. Intraoral periapical X-rays of left mandibular first molars were taken. Results: In the present study, 95 left mandibular first molars were evaluated by using CBCT and number of canals in the mesial and distal root were evaluated.  Among 95 left mandibular first molars evaluated, mesial roots had 2 distinct canals in 91.57% cases; 3 canals in 7.36% cases and only 1.05% cases had 1 canal.  In distal roots, 48.42% had 1 canal; 44.21% had 2 canals and only 7.36% had 3 canals.  In mesial root, type-4 canal configuration was significantly higher as compared to vaious types of root canal configurations seen [p-value=0.000].  In distal root, the most common canal configuration i.e. type-1 was compared with other types and p-value was calculated. Conclusion: Cone Beam Computed Tomography scans provides an excellent practical tool for immediate, nondestructive, non-invasive imaging option with the potential to detect most anatomic variations, while creating an accurate representation of external and internal dental anatomy.
