Abstract:
A dental handpiece for the polymerization of photosetting compounds or resins using as its polymerizing light source at least one LED, comprising:a connector element that can be adapted to external connectors of other types of handpieces carrying an electrical supply in order to take said electrical supply, and an electronic circuit connected to said connector element to process the electrical supply signal to supply said polymerizing light source wherein said connector element can be adapted to an external connector of a handpiece or ultrasound scaler in order to take electrical power destined for the resonator of the scaler and convey it, through the electronic circuit, toward the polymerizing light source and, wherein said electronic circuit provides a resonance circuit able to tune a supply frequency coming from said connector element, said frequency being set to vibrate the resonator provided in the scaler.
