Ultrasonic toothbrush is an ultrasonic energy ultrasonic cavitation effect in periodontal to remove the periodontal disease germs and unclean things, its clean and scope to cover all parts of periodontal. Excited ultrasonic toothbrush is in the brush hides inside a ultrasonic piezoelectric transducers, by installing in hollow handle the brush in MCU drive circuit incentive vibration, launch ultrasonic energy. Ultrasonic energy through the brush bristles of relay to the surface of the teeth and gums, on the one hand, the loose teeth and small plaque and tartar and teeth of adhesion, destroy bacteria in the gingiva bag and teeth of every department hidden the parasitic breeding, at the same time, through the touch of gum bristles passed to the surface of the gums supersonic energy penetration to gum internal, in the role of cell membrane, accelerate the blood circulation, promote metabolism, can restrain gum inflammation and gums bleeding, prevent gingival recession.
Ultrasonic toothbrush also by the electric drive, thus belong to electric toothbrush, namely ultrasonic electric toothbrush. But in many non-standard sales promotion, “electric toothbrush” is a single refers to “rotary electric toothbrush”. Rotary electric toothbrush bristles are arranged in the round, the use of rotating brush a head for contact friction clean, manual and brushing your teeth basically the same effect. And the head of sound waves toothbrush brush in appearance and manual tooth brush head completely, is through the high frequency vibration to undertake cleanness. But some special toothbrush used the combination two brush head (vibration and the rotating) way, we need to look at specific instructions to determine the types.
Ultrasonic toothbrush should refers to the frequency more than human hearing cap, namely 20000 hz. And many of the vibration frequency hundreds of Hertz only ordinary sound waves have also been some sellers toothbrush publicity for the ultrasonic toothbrush caused consumer confusion, in fact, those who “ultrasonic” toothbrush is the “voice sound waves”, that is to speak more than human when talking to the hundreds of Hertz acoustic frequency, have the suspicion of concept sameness. Voice of human language itself is defined frequency fuzzy, even use “super voice sound waves” standard would be difficult to confirm. And this kind of frequency difference between toothbrush is not big, there is no need to another division “super voice sound waves toothbrush” this classification.
