| Summary: | Background and objective: Anatomy of the root canal system and determining the number and form of the canals are the most important steps for successful root canal therapy without post-operative complications. The objective of the current research was to apply cone beam computed tomography as a mean to investigate the occurrence and characteristics of C-shaped canals in mandibular 1st and 2nd molars of the Erbil citizens.
Methods: the study was done retrospectively in February 2023 to September 2023 at the Private Dental Center, Erbil, Iraq. A group of individuals who had cone-beam computed tomography examinations were chosen for the study. The cone-beam computed tomography examinations were conducted at three distinct axial levels, and based on the Fan criteria, the mandibular molars were categorized as C-shape. cone-beam computed tomography scans were utilized to determine the existence and features of C-shaped canals. The data were examined based on the status of unilateral or bilateral, gender, types of C-shaped configurations, and distribution across the root thirds.
Result: The analysis of 676 molars from 222 patients revealed low occurrence rates of this anatomic feature in mandibular first molars 3 cases (0.97%), but mandibular second molars exhibit a comparatively greater frequency 28 case (7.62%). The incidence of C-shaped canals varied by status of unilateral or bilateral, gender, types of C-shaped configurations, and their distribution across the root thirds. There was a significant difference between the total number of c-shaped canals found in mandibular second molars in the male and female, on the other hand there was no significant difference in the mandibular first molar.
Conclusion: The results in mandibular second molars demonstrated a greater frequency of C-shaped canals compared to mandibular first molars. Females exhibited a greater incidence of C-shaped canals, and bilateral cases were more frequent in females than males. |
