摘要：

The apparatus includes a source of gas (air) bubbles (14) in a liquid medium, the gas bubbles having a size range which is associated with the size of bacteria alone or in colonies, on teeth or other surfaces. A source of ultrasound signals (16, 18) has a range of frequencies between 200 kHz and 2 MHz, the ultrasound frequency range including the resonance frequencies of a majority of the bubbles. The application of the ultrasound to the bubble/liquid stream directed toward the biofilm on the teeth results in a dislodging/removal of the biofilm.
