Abstract: A diagnostic toothbrush comprising, in combination, a toothbrush body, a standard brush head containing toothbrush bristles for brushing teeth, a diagnostic brush head containing a transducer that can detect a dental pathology, and a camera brush head that can produce video images of dental and oral structures. The standard brush head, the diagnostic brush head and the camera brush head can be interchangeably mounted on the toothbrush body. Data from the diagnostic brush head is transferred to the toothbrush body when the diagnostic brush head is mounted on the toothbrush body, data from the camera brush head is transferred to the toothbrush body when the camera brush head is mounted on the toothbrush body, and the data from the diagnostic and camera brush heads is transmitted from the toothbrush body to a computing device.

Abstract: A standard orthodontic retainer is modified on its surface opposite the palate and facing the patient's tongue with a light, a small battery to provide power for the light means, and a frame beneath the light that allows a template to be removably slid into the frame. The template consists of a design such as a heart, a letter of the alphabet, a symbol, or other design that, when the light is activated, shines the pattern onto the top of the tongue of the user. The template can be made so that the design displayed on the user's tongue is of any desired color or color combination. Alternatively, the color of the displayed design may be created by the color of the light or by an additional template consisting of an optical filter providing the desired color. A case for the retainer is provided. The case or retainer is provided with an indicator to allow the user to locate the retainer.
