摘要: 牙齿是人体最坚硬的器官,不易因外界理化因素的变化而降解、变形,利用牙齿推断年龄已广泛应用于法医学。通过牙齿影像推断年龄是过去使用最普遍的方法之一,而锥形束计算机体层摄影术(cone beam computed tomography,CBCT)技术的出现为牙齿三维影像的获取提供了新途径,具有照射剂量低、扫描时间短、成像精度高及费用低等优点。本文综述了CBCT技术的研究进展及其在牙龄推断中的应用。

Abstract: Teeth are the hardest organs in the human body. They are not easily affected by external physical and chemical factors to degrade or deform. Dental age assessment has been widely used in forensic practice. Dental image is one of the most common methods in the age estimation. The emergence of cone beam computed tomography (CBCT) technology provides a new way to obtain three-dimensional image of teeth. It has many advantages such as low-dose radiation, short-time scanning, high-precision image, and finical convenience. Recent development of CBCT technology and its application on age estimation are reviewed in this paper.
