C-shaped root canal system in mandibular second molars in an Iranian population: a cone-beam computed tomography study
Objectives: In order to achieve a cleaned root canal and successful root canal treatment, it is essential to be familiar with root canal morphology and anatomy. For this purpose, we assessed the prevalence and internal morphology of the C-shaped canal in the mandibular second molars
Methods: In this study, we used CBCT records of 260 patients, who were referred to the oral radiologic clinic in the city of Sari for diagnostic purposes. The images of the root canal systems of mandibular second molars were assessed with 1mm cross sections in the aspect of root canal morphology and anatomy. We considered the gender of patients and its relation with the prevalence of the C-shaped canal. Teeth with C-shaped canals were classified based on Fan et al.'s (51) classification. and the chi-square Test and student t-test were used for statistical analysis.
Results: Among 260 mandibular second molars, 30 teeth (11.5%) had C-shaped canals and type C1 was the most common among those teeth. In this study, gender had a significant relation with the prevalence of C-shaped canals, as women showed a much higher prevalence.
Conclusions: Considering the fact that prevalence of C-shaped canals among molar teeth in the northern population of Iran is relatively high, it is important for dentists to be familiar with this root canal anatomy and to consider the referral of these cases to an endodontist.
