ABSTRACT:
An ultrasonic dental insert having at least one light source. A first transducer generates ultrasonic vibrations. A connecting body has a proximal end and a distal end having a tip attached thereto. The proximal end is attached to the first transducer so as to receive the ultrasonic vibrations therefrom and to transmit the ultrasonic vibrations toward the tip attached to the distal end. A second transducer is disposed substantially proximate to the connecting body for generating a voltage signal in response to movement of a portion of the connecting body according to the ultrasonic vibrations. At least one light source substantially proximate to the tip is connected to and receives the voltage signal from the second transducer to generate light. The ultrasonic dental insert may be inserted into a handpiece for providing electromagnetic energy to the first transducer to generate the ultrasonic vibrations.
