OBJECTIVES: Familiarity with the shape of the root canal system is essential for the quality of endodontic treatment. C-shaped canals are anatomic variations most often encountered in mandibular second molars, and they pose an operational challenge to the clinician. The incidence of C-shaped canals varies widely in different populations. The aim of this study was to investigate for first time the incidence of C-shaped root canals in a European-Russian population using cone beam computed tomography (CBCT). The null hypothesis was that the incidence of C-shaped canals in western-Russian population will be similar to that of other Caucasian populations.
MATERIALS AND METHODS: A total of 300 CBCT scans of patients with two second mandibular molars were randomly chosen, screened and evaluated.
RESULTS: Forty-two patients (14%) had C-shaped canals. Of those patients, twenty-three (54.8%) had bilateral C-shaped canals, and 19 (45.2%) had unilateral C-shaped canals.
CONCLUSION: The prevalence of C-shaped canals in this European–Russian population is higher than that reported in other Caucasian populations, and in such cases, asymmetry between right and left is often encountered.
