ABSTRACT:
A lubrication device for a dental drill having an air turbine motor, or like handpiece, includes a housing having air and water passage extending therein for coupling a flexible supply hose to the handpiece. A conduit extends from the housing and provides a lubrication passageway in fluid communication with the pressurized air inlet passageway leading to the air turbine motor. The conduit includes a cap releasably secured to the end of the conduit. The nozzle of a lubricant reservoir may be inserted within the conduit after temporarily removing the cap for permitting the nozzle to be advanced through the housing and into the handpiece for lubricating the air turbine motor. The device may be provided as an adapter for insertion between the handpiece and the supply hose. Alternately, the proximal end of the housing may be permanently secured to the end of the supply hose.
