Abstract

Abstract: Objective: To evaluate the anatomical structure of C-shaped root canals in the mandibular second in Uyghur adults by cone-beam computed tomography (CBCT) and to investigate the prevalence of C-shaped canal in the mandibular second molars. Methods: The root canal shapes of the mandibular second molars of 100 Uyghur adults were studied on CBCT images. The incidence of the C-shaped root canals in mandibular second molars and the anatomical features of the C-shaped root canals were analyzed. Results: C-shaped root canals were found in 15% of the mandibular second molars in Uyghur adults. The patterns of C-shaped canals varied greatly. Conclusion: The incidence of C-shaped canals of the mandibular second molars in Uyghur adults is relatively high. The C-shaped canals vary greatly in their anatomical patterns. CBCT is of great significance for the diagnosis and treatment of C-shsped root canals in Uyghur adults.

Key words: Cone-beam computed tomography (CBCT), Mandibular second molar, C-shsped root canals
