Abstract
A method of lubricating a dental hand-piece wherein a small-sized lubricating oil sealed oiler is detachably mounted in a position adjacent to the rotor side of a rotor driving air passageway of a dental hand-piece device, the lubricating oil from said oiler is continuously mixed into rotor driving air to atomize said oil by utilizing the pressure and flow rate of said rotor driving air when said hand-piece is in use, and the mist oil thus obtained is supplied together with said air to said rotor to thereby continuously lubricate the rotor; and a novel small-sized oiler used in the method; are disclosed.
