AIM: The purpose of this study was to determine the root form and canal configuration in maxillary first premolars. MATERIALS AND METHODS: A total of 250 extracted @entity1 adult maxillary first @entity2651 from North Indian population were collected. Access cavities were prepared and the coronal pulp tissue was extirpated. The samples were stored in 5% @entity32428 solution for 5 days. They were then rinsed, dried, and dehydrated using increasing concentrations of @entity1068 (70, 80, and 95%) successively for 1 day. Teeth were rendered transparent by immersing in @entity27178 . India ink was then injected. The root canal morphology was examined under stereomicroscope. RESULT: 53.6% were single rooted followed by fused root form followed by two root form. 0.4% had three rooted maxillary first premolar. Variable root canal configurations were also found. @entity196 was most prevalent (33.2%). Two teeth showed an additional configuration. Lateral canals were present in 34.8% of the samples and intercanal communications in 16%. CONCLUSION: Within the limitations of this study, it was concluded that in North Indian 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.
