Ultrasonic scaler is an oral medical instrument that uses ultrasonic vibration with a frequency of 20Hz or more for scaling and scraping to treat calculus and dental plaque. Compared with traditional manual dental equipment, it has high efficiency, high speed, light trauma, and less bleeding time, effort and other advantages. In addition, its simple operation, does not require strict training, but also has good economic benefits, has been widely used in oral clinical. After years of application,we found that there are many problems with the use of ultrasonic scaler, which is summarized as follows.


1 Disinfection issues

Nowadays dental cleaning is mostly used for dental cleaning. If teeth are infected with other diseases, it is not worth the candle. Therefore, it is recommended that conditional medical units choose a scaler with a handle and a high-temperature, high-pressure sterilizer to ensure that there is no cross-contamination between patients.


2 No system training

Before using the scaler, read the instructions carefully and strictly follow the instructions for installation and operation. According to the author's survey of 30 oral doctors, only 8 people simply read the instructions. They think that the scaler is simple to operate and does not need to read the manual. In most cases, nurses or fellows or interns do the work. Due to the unclear use of the environment and operating routines of the dental scaler, it is easy to damage the machine and easily damage the teeth of the patient.


3 The operation is not standardized

In clinical work, patients are often confronted with questions about ultrasonic cleaning. They believe that ultrasonic cleaning will damage the teeth because their direct or indirect information is that ultrasonic tooth cleaning is painful. Some people's soreness will last for a long time. In addition to the patient's own reasons, it is also related to the improper operation of the doctor, such as the output power is too large, the head pressure is too large and so on. The correct operation should be: Before the scaler work, first turn down the power and increase the water volume. After the water is sprayed from the work head, adjust the power to the appropriate value according to the different working heads. The general output power should not exceed half of its maximum power. When it is necessary to increase the power in special situations, the operating time should be shortened as much as possible. Otherwise, the teeth are easily damaged, and the working tools and transducers are also easily damaged. Adjust the amount of water should be carefully adjusted after the output power is appropriate, so that the amount of water mist to 35ml/min or so is appropriate. At this point, you can start work, put the head on the tooth surface, and the teeth into angle, to light, steady, clean teeth to do a small amount of movement, so that the stones in the work of the rapid vibration under the exfoliation. Pay attention to the fulcrum during operation, lightly hold the device, and use appropriate force. If the contact with the tooth surface is too hot and the heat is too high and the tooth feels pain and discomfort, the normal pressure is 700dyne.


Scaling is a technically demanding job in dental outpatient treatment, but many doctors ignore its importance. For the benefit and health of patients, we should have enough awareness of dental cleaning, careful operation and serious responsibility.
