Cone beam computed tomography evaluation of root canal morphology of maxillary premolars in North-West sub-population of Pakistan

OBJECTIVES: To determine the number and configuration of canals in permanent maxillary premolars using Cone Beam Computed Tomography (CBCT) relationship between count patient gender northwest region Pakistan. METHODS: This cross-sectional observational study was conducted at Khyber College Dentistry (KCD) Peshawar, Data collected from July 1st to 30th December 2020, 133 patient’s CBCT scans with 266 premolar teeth. Roots frequency as well configurations were analyzed Vertucci canal classification. images obtained Radiology department KCD. SPSS-23 software, RESULTS: Type-I Vertucci's composition most common first (45.4%), followed by Type-IV (25.9%). frequent find second (64.2%), Type-III (15.4%). In Maxillary premolars, 247 (92.8%) single-rooted 19 (7.14%) two-rooted. 155 (57.9%) single-rooted, 110 (41.3%) two-rooted, one (0.37%) three-rooted. & premolar, single-root commonest root among males (92.7% 58.4%) females (30.8% 19%) respectively. Gender-based difference all not-significant. Mean tooth length 19.40±2.035 mm 20.08±2.395 crown 6.05±0.752 5.69±0.505 CONCLUSION: Most had classification configuration. diversity for All types observed premolars.
