This paper reports on the implementation of two diflerent approaches for visualization of dentistry data, discussing their role in providing adequate support for training, exploration, simulation and interaction in Dentistry applications. One of the approaches is a reconstruction technique based on the Delaunay Triangulation, and the other is a Direct Volumetric Rendering and Visualization technique with texture mapping. The results are evaluated in the light of the target applications, which are teaching and training in dentistry, as well as simulation of dental procedures and illnesses. Uses for multiple-technique visualization and exploration are discussed.
