Abstract: A dental cleaning implement comprising: a handpiece graspable at one end by a user, an oscillating drive within the handpiece, a head located at the opposite end of the handpiece which includes a coupler for releasably attaching a toothpick or an interdental toothbrush thereto. The oscillating drive is adapted to provide oscillations of up to 15,000 strokes per second, preferably from 1 to 5,000 strokes per second, and the implement may optionally further comprise a selector for varying the frequency of oscillation.

Abstract: Dental apparatus includes a handpiece graspable at one end by a user, and a head at the opposite end of the handpiece including a single nozzle, or a pair of nozzles, connectible to a source of a liquid, a gas, and/or powder. An electrical oscillating drive within the handpiece oscillates the head; and a manual fluid selector device manually selects the liquid, gas, and/or powder for conduction to the single nozzle or to the pair of nozzles.

Abstract: A dental cleaning implement includes a handpiece graspable at one end by a user, an electrical oscillating drive within the handpiece for oscillating the handpiece at a frequency of at least 5 Khz, a head at the opposite end of the handpiece including attaching apparatus for releasably attaching a toothpick or toothbrush thereto, and a spray nozzle for discharging a liquid spray in the region of the toothpick or toothbrush when attached to the head.

Abstract: Dental apparatus includes a tank of compressed sterile oxygen, or another compressed gas such as nitrogen, a source of a pressurized treatment liquid, and valves for coupling the oxygen tank or treatment liquid to the water inlet of the dental unit enabling the dental unit to be used for a wide variety of dental treatments, particularly when using a triple syringe for rinsing the canals in root canal treatment, or when using an ultrasonic scaler for dislodging hard deposits and stain.
