Year: 2026

Type: article

Abstract: Objectives Understanding the morphology of the root canal is important for successful endodontic treatment. Studies have revealed the role of geographical and racial diversity in root canal anatomical variations. Considering the lack of enough study on the prevalence of C‐shaped canals in maxillary molars in Iran, the present study aimed to investigate their prevalence in an Iranian population. Materials and Methods This cross‐sectional study was performed on 313 maxillary cone‐beam computed tomography (CBCT) scans of the Radiology Department of Tabriz Faculty of Dentistry. CBCT data were entered in NNT Viewer Version 2.21. The Martins classification system was used to identify and classify the C‐shaped canals. Results The C‐shaped canal was found in 1.5% and 2.7% of maxillary first and second molars, respectively. Also, the prevalence of C‐shaped canals was higher on the left side of the maxilla than on the right side without significant sex predilection. Conclusion The prevalence of C‐shaped canals in the maxillary first and second molars in an Iranian population was 1.5% and 2.7%, respectively.
