Abstract

BackgroundProviding comprehensive knowledge of the anatomy of human teeth is one of the basic functions of dental education, primarily because a thorough understanding of their internal structure is one of the prerequisites for any successful clinical intervention. Several techniques have traditionally been employed to study and visualize the complex internal organization of human teeth. In contrast to these invasive techniques, modern imaging systems permit non-invasive analyses of the three-dimensional structure of human teeth. Owing to the relative ease of acquisition, handling, and distribution of the respective data, digital imaging techniques will also significantly influence dental education. HighlightIn this article, a broad overview of traditional and modern techniques for the visualization of internal tooth structures is provided. Emphasis is placed on computed tomography systems and their application in endodontics. In addition, the results derived from a comparison of histology and micro-computed tomography are presented. Apart from its utility in basic research, digital data can also be employed to create interactive three-dimensional models that are particularly suitable for teaching purposes. ConclusionNon-invasive, three-dimensional imaging techniques, in particular the various modalities of computed tomography, have ushered in a new era of endodontic studies. Owing to their digital nature, the results derived from these techniques can not only be easily analyzed and distributed but also be rapidly integrated into teaching materials. Recent studies as well as the data shown in the present contribution suggest that digital educational materials lead to an improved understanding of the complex anatomy of human teeth.
