Evaluation of root canal morphology of mandibular premolars using cone-beam computed tomography in Rajasthan subpopulation - A retrospective study

Abstract

Aim: The purpose of this study was to evaluate root canal morphology in mandibular first and second premolars among Rajasthan subpopulation in Jaipur city using cone-beam computed tomography (CBCT). Materials and Methods: CBCT scans of 740 fully erupted mandibular first and second premolars were taken and assessed by two endodontists. Inter-examiner reliability was determined. Results: The root canal morphology of 380 permanent mandibular first premolars was assessed which showed canal configurations of Type I in 73.5%, Type V in 11.57%, Type IV in 8.42%, Type III in 2.63%, Type II in 2.1%, Type VII in 2.1% and Type VI and VIII 0% of the scans. The root canal morphology of 360 permanent mandibular second premolars was assessed which showed canal configurations of Type I in 88.88%, Type II in 7.77%, Type IV in 2.2%, Type III and Type V in 0.55%, Type VI, VII, VIII in 0% respectively of the scans. Conclusion: The majority of the population in Rajasthan have Vertucci's Type I configuration in both mandibular first and second premolars. However, other canal configurations can also be found in these teeth.

Assessment of Mandibular Molar Root Morphology Using Cone‑Beam Computed Tomography in Periodontitis Patients From Eastern Province: A Cross-Sectional Study

“…Matherne et al [15] and Mittal et al [16] showed the superiority of axial images of CBCT over other diagnostic methods in locating additional canals. Thus, CBCT imaging is not only noninvasive but also a highly sensitive method for morphological studies.…”
