A tooth is a heterogeneously structured object of translucent materials, such as enamel and dentin. The correct simulation of the appearance of teeth is useful in the field of dental restoration to detect the correct color and to develop materials for restoration. However, conventional surface reflection models do not capture the appearance of translucent materials accurately, because they assume that the rays of light are just reflected off the surface. For translucent objects, light not only bounces off the surface, but also interacts with the material under the surface. Therefore, physically correct rendering of teeth must take this into account to understand and model subsurface scattering. This paper discusses the optical characteristics of enamel and dentin. In addition, rendered images using volume photon mapping with Monte Carlo photon tracing are presented for enamel, dentin and biomaterials.

More about this publication?
  • CIC is the premier annual technical gathering for scientists, technologists, and engineers working in the areas of color science and systems, and their application to color imaging. Participants represent disciplines ranging from psychophysics, optical physics, image processing, color science to graphic arts, systems engineering, and hardware and software development. While a broad mix of professional interests is the hallmark of these conferences, the focus is color. CICs traditionally offer two days of short courses followed by three days of technical sessions that include three keynotes, an evening lecture, a vibrant interactive (poster) papers session, and workshops. An endearing symbol of the meeting is the Cactus Award, given each year to the author(s) of the best interactive paper; there are also Best Paper and Best Student Paper awards.
