Abstract: The invention provides a method of operating a dental scalar system having a vibrating scaling tip by continuously monitoring the amplitude and frequency of vibration of the tip which provides scaling power to a tooth in a patient's mouth. The amplitude and frequency of vibration of the tip is continuously adjusted to maintain a substantially constant scaling power. Preferably, the insert is vibrated at its resonant frequency and the system provides a substantially constant tip motion while the user varies the applied pressure between the tip and the tooth.

Abstract: The high voltage drive for the transducer of an ultrasonic transducer probe is provided by an active supply that monitors the high voltage supplied to the transducer by means of feedback, and responds to a decline in voltage during high voltage transmission by coupling charge from a capacitor to the high voltage supply line of the probe, thereby preventing a precipitous decline in the high voltage. Preferably the active supply and the capacitor are located in the probe connector enclosure.
