Abstract
A source of ultra violet light is directed onto the teeth of a patient via a mouthpiece which engages the gums above and below the tooth lines. A camera is attached and pictures may be taken of the teeth. By detecting differences in ultra violet absorption and reflection on the teeth, the detection of carious lesions may be undertaken in the relatively early stage of their development. Furthermore, deposits of dental plaque may be photographed readily and easily. The mouthpiece which may be disposable, is detachably securable to a base and is shaped at the mouth engaging end to engage the gums and hold the lips clear of the teeth during photography. It may be positioned in several locations relative to the mouth so that all of the teeth may be photographed and a mirror assembly may be attached so that the lingual and occlusal surfaces of the teeth may be photographed.
