ROOT AND ROOT CANAL CONFIGURATION OF MANDIBULAR PREMOLARS AND CANINES IN ARMENIAN POPULATION USING CONE-BEAM COMPUTED TOMOGRAPHY

Background: In clinical endodontics, cone-beam computed tomography (CBCT) provides essential diagnostic information and may be applied at all stages of treatment, from diagnosis and treatment planning to intraoperative assessment and post-treatment follow-up. This study aimed to analyze the root/root canal anatomy and configuration, determine the prevalence of C-shaped canals in mandibular premolars, and evaluate the root/root canal anatomy of mandibular canines in an Armenian population using CBCT imaging. Materials and Methods: Based on the use of Planmeca CBCT images, the number and morphology of roots and root-canals were assessed. A search on PubMed electronic database of the existing literature was performed. Results: This analysis is based on CBCT (Cone Beam Computed Tomography) data from 150 patients (93 females (62%), 57 males (38%), average age ≈57 years, based on birth years provided).The dataset includes observations on root morphology for various teeth, with varying numbers of observations per tooth type (not all teeth were assessed or present in every patient).Lower canines show minimal variation, predominantly single-rooted. Lower premolars exhibit more variability and showing higher C-shape prevalence. The prevalence was statistically higher in first premolars and equal for female and male individuals. Conclusions: It is important that clinicians pay complete attention to radiographs, have a true concept of the number of root(s) and canal(s), and prepare a correct access cavity before starting endodontic treatment.
