Background: Knowledge of root canal morphology is essential for performing a successful RCT that includes proper mechanical and chemical debridement, as well as effective root canal filling. Failing to clean and shape all root canals can result in treatment failure due to persistent infection from microorganisms left in the untreated canal. Aim of the study: To evaluate the presence of a 2nd root in the lower canine or a single root with two canals in the mandibular canine via CBCT.Material and methods: A total of 316 patients visited our clinic in Baghdad, Iraq, for various treatment modalities. After CBCT imaging to analyse the morphology of the permanent mandibular canine on each side, data were collected and cases with any side of the canine being absent, incomplete root formation, root canal-treated teeth, teeth with periapical pathology, or any internal or external tooth resorption were excluded. Results: Double-rooted mandibular canines were observed in 32 out of 632 cases (5%). A bilateral examination revealed 8 cases with bilateral double-rooted mandibular canines, while the others exhibited these on the left side only. Variable root canal configuration occurred in 36 cases (5.6%). Significant differences in data were observed between men and women. Conclusions: Most people’s mandibular canines have one canal in single root according to the CBCT examination. All double-rooted mandibular canines occurred in women and most of these were found on the left side. Additionally, mandibular canines with two canals in one root were more frequently observed in women than in men.
