The dental endo motor is composed of an ultrasonic emission system and an irrigation system. It has two cleaning methods, chemical and mechanical. Through the "cavitation" effect of ultrasonic, it can greatly enhance the antibacterial effect of the irrigation fluid and eliminate the necrosis in the root canal. The tissue and toxins are flushed out. The working principle is to use the ultrasonic transmitter system to make the enlarged needle (as shown in the picture) three-dimensionally vibrate, and the liquid spray system to prepare the root canal.
The advantages of the dental endo motor are: ultrasonic technology has biological effect, mechanical effect, thermal effect and cavitation phenomenon with the above three functions, and can effectively kill various bacteria in the root canal. Ultrasonic root canal preparation has good continuous washing, can remove the necrotic tissue debris in the root canal in time, effectively reduce the amount of bacteria in the root canal, and avoid the piston effect formed by the instrument in the infected root canal. The infected material in the root canal is not easy to exceed the apical hole. Due to the vibration of the ultrasonic file itself, it saves effort than twisting and pulling with fingers. It only needs to do the lifting and inserting movement instead of the rotating movement, so the breaking rate of the device and the accident rate of the device falling into the patient's mouth and being swallowed by mistake are greatly reduced. Thanks to the liquid spray device, there is no need to stop for flushing, saving operation time.
