One of the major differences between the piezoelectric ultrasonic instrument and the magnetostrictive ultrasonic instrument is which of the following?

Question

Quizplus · Accepted Answer

One clear difference between magnetostrictive and piezoelectric units is the working end surfaces that are adapted to the tooth. The lateral and back surfaces are adapted on a magnetostrictive insert and the two lateral surfaces only are adapted on the piezoelectric tip. This is one difference between the two units. The purpose of the water is similar in both units although the motion of the piezoelectric transducer does not emit heat. Cavitation and atomization are produced by both units. Frequency can be the same for both ultrasonic units, particularly if the magnetostrictive unit is autotuned. The type of stoke employed is similar with both units. The power used for both types of units is similar. Both units have adjustable power controls.
