Abstract:

Cone beam computed tomography （CBCT） changes the traditional method of oral X-ray imaging. In endodontics， CBCT is a reliable and nondestructive examination method. It’s sub millimeter spatial resolution and image information of hundreds of megabytes constitute a technical platform for the precision medicine of endodontics， which provides strong guarantee for evidence-based medicine. There is no doubt that the age of big data makes the fine diagnosis of the ultrastructure of the dental pulp tissue a new concept.

Key words: cone beam computed tomography, periapical radiograph, endodontics

摘要：

口腔颌面锥形束CT （cone beam CT，CBCT） 改变了传统口腔X线成像技术手段。在牙体牙髓病领域，CBCT作为一种非常可靠的、非破坏性的检查方法，其亚毫米级的空间分辨率、数百兆的大数据图像信息构成了对牙体牙髓病进行精准诊疗的技术平台，为循证医学提供了强有力的保证。无疑，口腔医学影像大数据时代使得对牙体牙髓组织超微结构行创新性精细诊断成为新的理念。
