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.
