Together with X-ray radiography and the description in the dental chart (odontogram), the collection of intraoral images is extremely important in dental identification. Recently, thanks to advances in digital devices for taking images in the oral cavity, problems with developing images and images being lost due to scanning errors have been minimized. However, in corpses where postmortem rigidity has firmly set in and burned bodies where the jaw has to be forced open, it is difficult to open the jaw enough to allow images to be taken. In addition, collection of intraoral images requires skill. Our goal was to determine the efficacy of a newly developed, small-scale color dental scanner in collecting intraoral images. The results showed that it was comparatively easy to obtain an entire image of the oral cavity with even a minimum degree of jaw opening. This should enable even a non-expert to perform oral image collection.
