X-ray microtomography (XMT), a miniaturised form of computed tomography, has been used to generate 3-dimensional volume data sets of the X-ray absorption of human teeth in vitro, with a resolution of approximately 40 microns (cubic voxel sidelength). Examples are presented of images relevant to dental morphology, cariology, and cavity preparation and restoration. Applications of XMT imaging to dental education are discussed in the context of new approaches to visual learning through computer-assisted methods.
X射线显微断层扫描（XMT）是计算机断层扫描的一种小型化形式，已被用于在体外生成人类牙齿X射线吸收的三维体积数据集，分辨率约为40微米（立方体素边长）。文中给出了与牙齿形态学、龋病学以及窝洞预备和修复相关的图像示例。在通过计算机辅助方法进行视觉学习的新途径背景下，讨论了XMT成像在牙科教育中的应用。
