What are ultrasonic scalersdentistry?

Answer 1

Ultrasonic scalers are used to remove calculus rapidly from the tooth surface. The scaling tip vibrates in the ultrasonicrange of 20-45 kHz (i.e. 20,000 to 45,000 times per second), with an optimum frequency between 18 kHz and 32kHz. Most of the scaling power is available at the tip, which is cooled with a jet of water. There are three basic types - magnetostrictive, piezo-electric and Odontoson™. The scaling tip vibrates and follows a pattern depending on power rating and type - elliptical, curved linear or figure of 8. The water is energised as it passes over the tip to provide cavitation, which results in a scouring action. Because of the heat generated at the tip, it is essential to keep the tip moving over the teeth.
