Abstract: An intraoral dental instrument includes an elongate handle or body and a mirror that is releasably attachable to a distal end thereof. An LED housing disposed in the handle proximate a light entrance surface of the mirror includes a housing body sized to retain at least one LED and a reflector attached to a distal end of the housing body. The reflector has an inwardly tapered cavity covering a LED lens envelope for focusing illumination from the at least one LED onto a portion of the light entrance surface of the mirror.

Abstract: A diagnostic assembly includes an instrument having a body portion and a distal camera head, in which a protective sheath encases the instrument body and includes a transparent window for allowing the camera head to view a target. A releasably attached handle overlays the instrument body and includes inner surfaces conforming to the instrument body to clamp the sheath in a predetermined position to prevent the sheath and the transparent window form being twisted during use.

Abstract: A film holder for a video display system, having a probe with a head portion, a processor, a monitor, and a printer for producing a permanent hard copy of the image received by the probe, includes a housing for positioning the film relative to the head of the video probe. The housing is provided with an aperture for receiving, positioning, and securing the head of the video probe within the housing. The housing also includes a diffuser for diffusing light entering the housing, and a slidable frame positioned between the diffuser and the housing aperture. The sliding frame is employed to secure the film at a predetermined distance from the head of the video probe. The sliding frame is provided with quick release fasteners so that individual pieces of x-ray film are easily interchanged within the frame.
