Ultrasonic cleaning is to use the cavitation effect, acceleration effect and direct inflow effect of ultrasonic in the liquid to directly and tactfully affect the liquid and dirt, so that the dirt layer is distributed, emulsified and peeled to reach the cleaning target. At present, more cavitation and direct flow are used in the ultrasonic washing machine.
According to the frequency wave, it can be divided into three types: infrasound wave, acoustic wave and ultrasonic wave. The frequency of infrasound wave is below 20Hz; the frequency of sound wave is 20Hz ~ 20kHz; the frequency of ultrasonic wave is above 20kHz. The infrasound wave and ultrasonic wave in it can’t be heard by ordinary people. Because of the high frequency and short wavelength, the ultrasonic wave has good target and strong penetration, which is the reason of designing and manufacturing the ultrasonic washing machine.
It is one of the methods for protecting teeth and cleaning teeth. In today’s society, a lot of people will do ultrasonic tooth washing.
1. Complete: the key point of ultrasonic tooth washing lies in the subgingival calculus, which is the key cause of periodontitis. Only when the area is clean, can periodontitis be prevented and gum bleeding be improved. This is one of the advantages of ultrasonic tooth washing.
2. Painless: This is also the most important advantage of ultrasonic tooth washing. Adjust the frequency of the head of the cleaning machine according to the amount of calculus of the person who washed the teeth, so as to ensure that the process of tooth washing can be completed in a painless environment.
3. Polishing after operation: it can leave microscopic tiny scratches on the surface of teeth after cleaning. After polishing, it is better to make the teeth more bright and not easy to attach calculus and tooth stains.
4. Safety: all the equipment is sterilized by high temperature and high pressure. The advantages of ultrasonic tooth washing can be used to prevent cross effects.
