Evaluation of Root canal morphology of maxillary first premolar by clearing technique in Kashmiri population: An in-vitro study
Shabir Ahmad Bhat, Mushtaq Mohammad Bhat, Ab. Wahid Zargar

Aim: The aim of  this study was to determine the root form and canal configuration in maxillary first premolars. Materials and Methods: 200 extracted human adult maxillary first premolar teeth from kashmiri population were collected. Access cavities were prepared and the coronal pulp tissue was extirpated. The samples were stored in 5% nitric acid solution for 5 days. They were then rinsed, dried, and dehydrated using increasing concentrations of ethanol (70, 80, and 95%) successively for 1 day. Teeth were rendered transparent by immersing in methyl salicylate. India ink was then injected. The root canal morphology was examined under stereomicroscope. Result: 53% were single rooted followed by fused root form followed by two root form. Variable root canal configurations were also found. Type IV configuration was most prevalent (32.5%). Two teeth showed an additional configuration. Lateral canals were present in 36% of the samples and intercanal communications in 20%. Conclusion: Within the limitations of this study, it was concluded that in kashmiri population, there was an increased propensity for types IV, I, II, and III canal morphologies in maxillary first premolars. Single root form was most common.
Key words: Canal morphology; clearing technique; dehydration; demineralization; methyl Salicylate; nitric acid.
