Abstract

A dental system may transilluminate teeth using a light source for producing examination radiation by directing the examination radiation at a tooth to be examined. An optical image of the tooth illuminated by the examination radiation may be acquired. The light source may include a light-guiding and/or light-deflecting element that faces the tooth to be examined. Light-guiding and/or light-deflecting elements may be embedded in a transparent, flexible coupling body that is provided to rest on the tooth or the gingiva of the tooth.
