What is the action created by the formation and collapse of bubbles in water by high-frequency sound waves surrounding an ultrasonic tip?

Question

Quizplus · Accepted Answer

The definition given is that of cavitation. Cavitation results in lavage, the therapeutic washing of the periodontal pocket or sulcus that occurs with both the piezoelectric and magnetostrictive units. Acoustic microstreaming occurs because agitation of the fluids surrounding a rapidly vibrating ultrasonic working end has the potential to destroy or disrupt the oral biofilm. Clinical power is the ability of the instrument to remove dental calculus. Increasing the power increases the distance the working end moves and the length of the stroke. Mechanical action refers to the vibration of the ultrasonic instrument's working end. Amplitude is synonymous with clinical power.
