Ultrasonic cleaners use high frequency sound waves to generate millions of small bubbles in a cleaning solution that collapse, disrupting chemical bonds and removing debris from dental instrument surfaces through a process called cavitation. This cavitation facilitates more efficient cleaning than hand scrubbing as it allows the cleaning solution to rush into hard to reach areas.

1. ULTRASONIC CLEANERS

4. 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.

7. 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.

8. 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.

9. 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.

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