Evaluation of Root Canal Morphology of Lower Lateral Incisors using Cone Beam Computed Tomography in an Indian Subpopulation

Aim: To aim of the current study was to evaluate the root canal morphology of lower lateral incisors in an Indian subpopulation using Cone-Beam computed tomography. Material and Methods: The CBCT images of 256 patients were obtained from the Department of Oral Medicine and Radiology of the University. Various parameters such as number of roots, number of root canal and canal configuration were evaluated and recorded and then classified according to Vertucci's classification of root canals. Results: The most common root canal morphology is for Vertucci's Type 1 which is 40.2%, and Type 2 being 33.6%. The other types being Type 3(11.4%), Type 4(6.3%), Type 5(1.9%), Type 7(4.7%) and Type 8(1.9%). Conclusion: From the assessed data it was seen the root canal morphology of lower lateral incisors exhibited a higher incidence of Vertucci's Type 1 and Type 2 andother configurations being Type 3, Type 4, Type 7, Type 5, Type 8. Type 6 was not to be seen in the assessed sample. The variation in the root canal morphology was seen most commonly in the male population than in female population.
