Abstract

Objective: Knowledge of root and root canal morphology is a prerequisite for effective nonsurgical and surgical endodontic treatments. The external and internal morphological features of roots are variable and complex. Hence, the aim of this cone beam computed tomography (CBCT) study was to evaluate the root canal morphology of permanent canines in a Turkish population using two classification systems (Vertucci 1984 and Ahmed et al. 2017).

Material and Methods: A total of 2,000 canine teeth were examined using CBCT. The number of roots was identified, and root canal configurations were classified according to Vertucci’s classification and a new system for classifying root and canal morphology. Fisher’s exact test was used for statistical analysis, and the level of significance was set at 0.05 (p = 0.05).

Result: More than half of the canines were single-rooted. The canal configuration type I was the most common in all canines, while type 3 was the second most common. According to the new system, the code 1C1-1 was the most common for canines, whilst 1C1 (A1) codes were the second most common for all canines. It has been found that the two-channel morphologies in double-rooted canines show significant differences. Sex and age were not effective factors for canal complexity (p>0.05).

Conclusion: Canines in a Turkish subpopulation had a slight variation in root and canal anatomical variations. Clinicians should be aware of where canals merge or diverge to prevent missing canals. The new system for classifying canal morphology describes the root and canal configurations in a more accurate and practical manner compared to the Vertucci classification.
