ABSTRACT Background and objectives The aim of this study was to compare internal anatomy between first and second mandibular premolars and to study different percentage variations of root canal morphology of mandibular premolars in Gujarat population based on Vertucci's classification by clearing technique. Methodology A total of 80 extracted intact permanent mandibular premolars (40 each mandibular first premolar and mandibular second premolar) with fully formed apices were collected. Access cavity was prepared with endo access kit, all samples were placed in 2.5% sodium hypochlorite for 48 hours, after that all samples were washed in running water for 2 hours. After washing, all samples were transferred to 5% nitric acid, for decalcification, for 72 hours, with the acid being changed every 24 hours and stirred once every 8 hours. All samples were washed in running water and dehydrated using ascending grades (70%, 80%, 90% and 100%) of isopropyl alcohol for 2 days. Finally, they were rendered transparent by immersion in methyl salicylate for 15 minutes and then India ink dye was injected into the access cavity. The anatomy of the root canal was observed and classified based on the Vertucci's classification. Statistical analysis Parametric Z-test was used to compare the variation between mandibular first and second premolars. Results In mandibular first premolar, type 1 was found in 20%, type 2 was 5%, type 3 was 5%, type 4 was 25%, type 5 was 12.5% and type 6 was 2.5% of total samples. Whereas, in mandibular second premolar, type 1 was found in 80% out of all samples, type 4 was 2.5%, type 5 was 17.5%. Type 2, type 3, type 6, type 7 and type 8 were not found in this study. Conclusion Mandibular first premolar showed higher variation (75%) compared to mandibular second premolar (37.5%). Clinical significance The knowledge of variations in the root canal morphology of the mandibular premolars can enhance the level of endodontic treatment of mandibular premolars.
