The ultrasonic toothbrush is the fourth generation toothbrush after the conventional toothbrush, electric toothbrush and sonic toothbrush (200-300Hz). Ultrasonic wave refers to that at the audible wave length on the ultrasonic wave spectrum(20-20000Hz), at present obtained the widespread application including stomatology many domains.
Ultrasonic wave at 1.6 million times per second ( 16 million vibrations per second ) penetrates human body easily, producing an ultra-critical "vacuum" effect of water which cleans the teeth. In addition, the unique massage effect and warming effect of ultrasonic wave enhances gum blood circulation and keep it health.
Ultrasonic toothbrush doesn't apply tooth- paste and its special cleaning effect is far more than what the conventional toothbrush and electric toothbrush can come up to.
The clinic experiments in the US indicates regular use of the ultrasonic toothbrush for a month removes 97% of plaques and reduces by 74% the plaques formed during night time. In addition, the ultrasonic wave commands effect on the cell membrane and that way it prevents effectively gum inflammation. A significant drop in periodontal bleeding and pus has been observed among 60% of the experiment participants. |
