Abstract: In a preferred embodiment of the invention, a mirror antiscratch protector case mountable on a dental mirror, having a spaced-away recess portion of an interior concave wall surface with spaced-apart points on the interior concave wall surface on each of opposite sides of the recess portion supportable of mirror bezel structure of mirror mounting structure, and having a biasing spring positioned to press a mounted dental mirror's mirror bezel structure against the spaced-apart points, and having a barrier structure pressing against a leading edge of the mirror bezel structure when the mirror is mounted within the protector case such that the reflective surface of the mounted mirror is retained opposite the recess portion, with opposite edges of the protector case in alignment with the spaced-apart points converging from a wide to narrow width of the protector case such that varying sizes of dental mirrors are received and such that narrower portions of the concave wall surface serve as the barrier structure.

Abstract: A dental hand mirror unit includes a generally hollow handle portion which supports a mirror at one end and has its other end releasably coupled to a cap or valve member. Air is fed through the cap member and handle portion and is directed outwardly along the upper surface of the mirror to prevent it from fogging. Rotation of the cap member controls the flow of air to the mirror as desired. In one embodiment, light from a light dispersion element positioned in a chamber beneath a two-way mirror passes outwardly through the mirror and into a patient's mouth. In addition, light is transmitted to such dispersion element by a bundle of optic fibers positioned within an optical fiber passageway portion of the dental hand mirror unit.

Abstract: A dental implement is disclosed which consists of a lip and cheek depressor or retractor adapted for mounting on the shank of a dental instrument adjacent the work portion of the instrument, such as a mirrored surface. The retractor is mounted for rotation about the longitudinal axis of the shank and may be detachably affixed thereto to facilitate interchangeability of retractors of various sizes and shapes.

Abstract: A diagnostic lamp is provided for fluorescent excitation of a fluorescible material applied to the parts of the body to be tested, in particular the teeth and gums. The lamp is battery operated and in accordance with a disclosed embodiment the light source may be at least one ligth-emitting diode capable of emitting light in a narrow range of wave lengths. A dispenser may be mounted with the lamp for containing the fluorescible material.
