摘　　要：口腔颌面锥形束CT(Cone-beam computer tomography,CBCT)因具有空间分辨率高、能提供三维图像、图像无失真、放射剂量低和扫描时间短等优点,被广泛应用于口腔医学的医疗、教学和科研中。利用CBCT既能精确测量牙齿和根管的长度,判断牙根、根管的数目和形态,又能准确诊断牙内陷及罕见根管形态的病例。因此,本文就CBCT在牙体解剖学中的研究进展作一综述。Cone-beam computer tomography（CBCT） has been widely used in dental treatment, teaching and scientific research for its high space resolution, 3D images, non-distorted images, low radiation and short scanning time. CBCT can accurately measure the length of the teeth and root canal, determine the number and morphology of root and root canal, and highly accurately diagnose the dens invaginatus and rare root canal morphology. Therefore, the aim of this article is to review the application of CBCT in the study of dental anatomy.
