This type of ultrasonic uses vibrations in an elliptical pattern.

  1. Piezoelectric

  2. Magnetostrictive

  3. Sonic

  4. Optic

The correct answer is: Magnetostrictive

The correct answer is B. Magnetostrictive ultrasonic units use magnetostrictive stacks to create vibrations in an elliptical pattern. This type of ultrasonic scaler is commonly used in dental offices for its efficient removal of calculus and plaque due to its elliptical motion. Option A, Piezoelectric ultrasonic scalers rely on the piezoelectric effect to generate linear vibrations, not elliptical vibrations. Option C, Sonic scalers, operate in a lower frequency range compared to ultrasonic scalers and use the energy from compressed air to create vibrations. Option D, Optic, is not a type of ultrasonic scaler.
