This energy can induce acoustic streaming and cavitation of the irrigation solution (27).
This device uses patented sonic flow technology that causes acoustic streaming in the root canal and operates at a low frequency (13,14).
* Ultra-sonic: efficient cavitation and acoustic streaming
* Ultra-fast: optimized disinfection in several sequences of 30 seconds each * Ultra-performing: penetration and action of the irrigant in all the zones which are inaccessible for the instruments
, buoyancy, Bjerknes forces, and bubble collapse are not considered .
Ultrasound therapy decreases inflammatory infiltrate (Enwemeka, 1989) by increases cell permeability by setting up cavitations and acoustic streaming
The interesting effect of viscosity is the flow produced by high-frequency oscillations of a boundary where the flow oscillations do not average to zero, such steady flow is referred to as "steady streaming" or "acoustic streaming" or "nonlinear streaming" [3, 4].

Timmerman and his colleagues assessed two additional variables (the presence of acoustic streaming
and ovarian crescent sign) next to several clinical variables, such as pain during examination, he noted.
