| Outline of Final Research Achievements |
In this study we have developed a new cleaning system in which high-frequency ultrasonicis superposed on a water flow from the nozzle. As a result, we successfully downsized the transducer in the frequency band around 350 kHz, and the sound pressure increased with the applied voltage dependent. The effect of removal of biofilm was about 17% at 10 W. There was a negative correlation between applied power and residual biofilm. In addition, titanium surface was not damaged and the main component was TI 96%, when observation with EDX. There was no acute response of inflammation such as edema in miniature swine oral tissues.
