锥体束CT对维吾尔族成人下颌第二磨牙C形根管的研究

目的: 通过锥体束CT(cone-beam computed tomogphy,CBCT)成像系统对新疆维吾尔族成人下颌第二磨牙C形根管的发生率及其形态特征进行研究。方法: 选择来我院体检且下颌牙列完整的100名维吾尔族成人,进行CBCT扫描,观察下颌第二磨牙的根管形态。结果: C形根管的发生率为15.0%,C 形根管类型变化多样。结论: C形根管在下颌第二磨牙有较高的发生率,且解剖形态存在较大差异。CBCT在C形根管的诊断方面具有重要作用,可以为维吾尔族成人下颌第二磨牙C形根管的临床诊疗提供依据。

Evaluation of C-shaped Root Canals in Mandibular Second Molars in Uyghur Adults by Cone-beam Computed Tomography.

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.
