Evaluation of Root Canal Anatomy and Morphology of Lower First Premolar Teeth in a Turkish Subpopulation: Cone Beam Computed Tomography Study

Objective: The aim of the present study is to evaluate the anatomy and morphology of mandibular first premolar teeth in a Turkish subpopulation, based on common classification using cone beam computed tomography. Methods: Five hundred and five teeth that met in inclusion criteria included the study. Teeths classified according to the Vertucci Classification. All evaluations were made by two endodontists for each tooth. After recording demographic data, the root canal configuration of the teeth, number of roots, number of canals, direction and level of canal branching were recorded and evaluated. The results were statistically analysed using chi square Results: The most common morphology in both tooth group was Vertucci Type 1, while the second most common morphology was Vertucci Type 5.A significant difference was found between root number and gender (p.05) According to the findings of the current study, a statistically significant difference was found between Vertucci classes and gender. (p.05) Conclusion: Having information about the morphology of premolar teeth with variable anatomical variations will prevent possible complications and increase success. CBCT is complementary to clinical applications in fully determining anatomical variations in three dimensions.
