In most dental practices, instruments are cleaned in an ultrasonic cleaner. This type of unit removes bioburden by using sound waves generated by electrical energy.

As the sound waves move through the liquid cleaning solution, they cause the formation and bursting of millions of small bubbles. This “cavitation” process functions by disrupting chemical bonds, which hold the debris on instrument surfaces. This facilitates cleaning.

Ultrasonic cleaner uses high frequency wave that agitate liquid within the sink (tank) creating a rapid formation and collapse of bubbles; also known as CAVITATION.

As the bubbles collapse during the cavitation process the cleaning solution rushes into hard to reach areas of objects submerged in the sink (tank). This process is highly effective to gently removing all contaminants and dirt from both the surface and hard to reach areas of intricately shaped objects.

The resulting cleaning of contaminated instruments is more efficient as compared to hand scrubbing with a scrub brush.
