摘要：

牙周组织是维持牙齿稳定、承担牙齿咬合力的重要结构，临床中常用影像学手段对其进行评估。相较于传统成像设备，锥形束CT（CBCT）具有成像精确、空间分辨率高、有效放射剂量小等优势。CBCT可对牙周组织进行精准评估，但其精准性具有组织特异性。文章从CBCT技术特点及其对牙周组织评估的应用进展方面做一综述。

Abstract:

Periodontal tissue is an important structure to maintain teeth stability and distribute the occlusal force of the teeth. It is often evaluated by imaging methods in clinical practice. Compared with traditional dental imaging equipment，cone-beam CT（CBCT）has the advantages of accurate imaging，high spatial resolution and lower effective radiation dose. CBCT can assess periodontal tissue accurately，but the accuracy has tissue specificity. This review summarized the technical characteristics of CBCT and its application progress in the evaluation of periodontal tissue.
