Abstract
A heated dental mirror is disclosed which includes in combination a handle portion and separable reflecting portion. The handle portion includes a hollow, cylindrical body within which are positioned a two cell electrically rechargeable battery. The body includes a first phone jack to facilitate recharging of the battery by employing a battery recharging stand. An electrical circuit is provided in the handle portion which includes an LED and a second phone jack wherein electrical energy from the battery will simultaneously energize both the LED and the second phone jack. The separable reflecting portion is removably connectable at the second phone jack to facilitate sterilization of the reflecting portion when desired. The reflecting portion includes a pair of first and second reflecting surfaces, one of which surfaces is positioned to receive and reflect illumination from the LED. An elongated mirror support shaft is wired to accommodate a resistance type electrical heater circuit, which circuit generates heat at all times when the reflecting portion is connected to the body portion. Heat energy from the heater circuit is thermally conducted to the first and second reflecting surfaces and sufficient heat is provided to elevate the temperature of the first and second reflecting surfaces to a temperature at or above the dew point temperature of the air in the patient's mouth.
