  • Rotary dental instrument and methods of use
    Patent number: 6315557
    Abstract: A rotary dental instrument for rotating a cutting tool at a repair site of a patient's tooth and providing an irrigating liquid to the repair site. The instrument includes a handpiece having a rotating file coupled to a motor and an irrigating port coupled to a pump. A control associated with the instrument automatically starts discharge of the irrigating liquid from the port at a predetermined time after starting the motor. This provides an automatic delay between rotation of the rotatable element holding the file and discharge of irrigating liquid from the port. A corresponding method involves providing a starting input to the motor, waiting a predetermined amount of time after the cutting tool or rotatable element begins rotating, and automatically discharging the irrigating liquid after the predetermined amount of time has elasped.
