Title (EN) APPARATUS FOR CLEANING TEETH USING A VARIABLE FREQUENCY ULTRASOUND
(FR) APPAREIL DE NETTOYAGE DE DENTS À L'AIDE D'ULTRASONS À FRÉQUENCE VARIABLE
Abstract:
(EN) 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 2MHz, 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.
(FR) L'appareil comprend une source de bulles de gaz (air) (14) dans un milieu liquide, la plage de taille des bulles de gaz étant associée à la taille de bactéries seules ou en colonies, qui se trouvent sur des dents ou autres surfaces. La plage de fréquences d'une source de signaux ultrasonores (16, 18) est comprise entre 200 kHz et 2 MHz, la plage de fréquences ultrasonores comprenant les fréquences de résonance d'une majorité des bulles. L'application des ultrasons au flux de bulles/ liquide orienté en direction du biofilm qui se trouve sur les dents a pour conséquence de déloger/d'éliminer le biofilm.
