Applications:
Piezoelectric transducers are used by dental surgeons in ultrasonic dental scalers for scaling and root planning, which involves the removal of plaque, stains, tartar or calculus on the surface of teeth and roots. The scaler tip insert vibrates against the tooth, and then create ultrasound waves that break apart the hard calculus on the tooth structure. The piezoelectric ceramics in the ultrasonic dental scalers application operates as a transducer by rapidly adjusting dimensions when it is excited by an electrical signal at high frequency.Water also flows out of the scaler, and combined with the vibration,produces a cavitation effect where millions of tiny bubbles collapse with enormous energy, causing the cell walls of bacteria in the plaque to break up.
