A heat sterizable, independent dental water supply apparatus has a hand piece control head and a water supply container removably connected to the control head. The apparatus in connectible with a dental, hand piece, an air source and a controller such as a dental foot pedal. In use, the apparatus supplies sterile irrigation water at the hand piece under the control of a dental practitioner. The apparatus is particularly useful of oral surgeons, prosthodontists and other dental specialists. Methods of making and using the apparatus are also disclosed.

1. A dental water supply apparatus for use with a dental hand piece, comprising a hand piece control head adapted to be connectible to an air supply, an actuator, and a dental hand piece, the control head including an air actuated pilot valve, the pilot valve including: a body with a central lumen extending from a first end to an opposing second end, an air at the first end, a water inlet disposed along the length of the central lumen, and a water outlet disposed at the second end,a valve assembly including a major piston actuable by inlet air, a shaft extending from the major piston to two minor pistons disposed between the water inlet and the water outlet;whereby the major piston is spring biased in a normally closed position the minor pistons prevents flow of water from the water inlet to the water outlet; andwhereby inlet air actuation of the major piston causes it to be in an open position permitting flow of water from the water inlet to the water outlet;wherein the lumen has a first chamber in which the major piston is movably disposed, a second chamber extending from the first chamber and being communicatively connected with the water inlet, and a third chamber extending from the second chamber to the water outlet;a spring is disposed in the first chamber behind the major piston; andthe two minor pistons disposed on the shaft, one disposed between the first and second chambers and the other disposed between the second and third chambers;a removable water supply container, the container supplying water to the hand piece control head; andthe hand piece control head being directly connectible to and disconnectible from the water supply container. 2. The dental water supply apparatus of claim 1, wherein the hand piece control head is constructed of autoclavable materials. 3. The dental water supply apparatus of claim 1, wherein the hand piece control head includes a body that is directly connectible to the water supply container via a threaded adapter portion of the body,a diaphragm disposed on the body on a side opposite that of the threaded adapter portion,a cover, disposed on the diaphragm, andwherein the pilot valve is connected to the body. 4. The dental water supply apparatus of claim 3, wherein the cover is adapted to be connected to an air supply, wherein the pilot valve is adapted to be connected to an air supply of an actuator, and wherein the body receives water from the container and distributes it to the pilot valve for transmission to the hand piece. 5. The dental water supply apparatus of claim 1, further comprising the actuator and the dental handpiece. 6. The dental water supply apparatus of claim 5, further comprising the air supply. 7. The dental water supply apparatus of claim 5 further comprising a hand piece drive mechanism. 8. The dental water supply apparatus of claim 1, wherein the control head has a threaded adapter, wherein the water supply container has a threaded adapter, and wherein the threaded adapter of the control head screws onto and off of the threaded adapter of the water supply container directly connecting and disconnecting the control head to and from the water supply container. 9.
