   A second review found no clinical evidence for the dynamic fluid activity of the Sonicare toothbrush being more effective in plaque removal than an Oral-B oscillating/rotating electric toothbrush. [4] A 2007 study comparing the two found the rotation/oscillation brush to be more effective in single-use plaque reduction. [5]

5. Ultrasonic cleaning - Wikipedia

   Ultrasonic cleaning is a process that uses ultrasound (usually from 20 to 40 kHz) to agitate a fluid, with a cleaning effect. Ultrasonic cleaners come in a variety of sizes, from small desktop units with an internal volume of less than 0.5 litres (0.13 US gal), to large industrial units with volumes approaching 1,000 litres (260 US gal).

   Plaque and calculus deposits are a major etiological factor in the development and progression of oral disease.

However, if left for an extended period of time, the inflammation may begin to affect the supporting tissues, in a progression referred to as periodontitis. [24]: 96–97 The gingivitis response is a protective mechanism, averting periodontitis in many cases.
