Dental fluid control apparatus
First Claim
1. Dental apparatus for use with a dental unit having a water inlet to be coupled to a source of pressurized water for driving and/or cooling dental appliances to be coupled to the dental unit, or for flushing the treatment site, and a air inlet connectible to a source of compressed air;
- said dental apparatus comprising;
a tank of compressed oxygen;
a source of pressurized liquid; and
valve means for coupling said tank of compressed oxygen and said source of pressurized liquid to the water inlet of the dental unit, said valve means including;
means for selectively coupling said air inlet of the dental unit to said source of compressed air or to said tank of compressed oxygen;
and means for selectively coupling said water inlet of the dental unit to said source of pressurized water, to said container for a treatment solution, or to both said container for a treatment solution and said tank of compressed oxygen.

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.
