Abstract: A device comprising a universal light-adapter suitable for use with a wide variety of dental mirrors. The body of the adapter is a tubular structure, closed on one end, into which the handle of an ordinary dental mirror may be inserted and secured in place. Mounted at the forward end of the adapter is a lighting element comprising a light bulb and pressure switch conveniently positioned to operate the light. The light bulb throws a beam of light onto the dental mirror, providing greater visibility to the dentist at the time of treatment or examination. The power for the device is provided by a rechargeable battery in the lower part of the tubular structure and appropriately connected to the light bulb and pressure switch. The whole device is insertable into a convenient stand when not in use, which also serves to house a charger unit for recharging the battery supply.
