Ultrasonic tooth cleaning machine is the use of frequency of 20Hz or more for ultrasonic vibration cleaning and scaling calculus, dental plaque oral medical equipment, compared with the traditional manual cleaning teeth, with high efficiency, speed, light trauma, less bleeding , Saving time, effort and other advantages. In addition its operation is simple, does not need the strict training, also has the good economic efficiency, at present already widely applied to the oral clinical. I applied many years later, found that the use of ultrasonic scaler there are many problems, are summarized below.
1.disinfection problems
Clinics are now mostly clinical dental care, if the teeth when the infection of other diseases, is worth the candle. Therefore, the proposed conditional medical units to choose the handle, the head can be high temperature, high pressure disinfection of scaling machine to ensure that patients do not occur between the cross-infection.
2.No system training
Before using the scaler, you should read the instructions carefully and follow the installation and operation instructions strictly. According to the author of the 30 dentists survey, only 8 simply read the instructions, they believe that scaling machine is simple, no need to see the instructions, and most cases by nurses or students, interns to do the work. Because of the use of scaler environment, the conventional understanding of unclear, easy to damage the machine, but also easy to damage the patient's teeth.
3.operation is not standardized
In clinical work, often encountered in patients with ultrasonic cleaning teeth, they believe that ultrasonic scaling teeth will damage the teeth, because they are direct or indirect information is ultrasonic scaling teeth pain, some people's pain will continue for a long time, In addition to the patient's own reasons, but also with the doctors improper operation, such as the output power is too large, too much pressure on the head and so on. The correct operation should be: before scaling machine work, lower the power, adjust the water volume; water from the work head after the discharge, according to the use of different work head, adjusting the power to the appropriate value. General output power should not exceed half of its maximum power, special circumstances need to increase power, try to shorten the operating time, otherwise, easy to damage the teeth, but also easy to damage the work of cutting tools and transducers. Water should be adjusted in the output power after careful adjustment, so that the water mist volume of 35ml / min or so is appropriate. At this point, you can start to work on the tooth surface, with the teeth into 15deg; angle around, to light, steady, clean head to do a small move constantly, so that stones in the work of the first rapid stripping layer of exfoliation. Operation attention to the fulcrum, light grip equipment, force appropriate. If too close contact with the tooth surface is easy to produce heat is too high, toothache discomfort, the general pressure to 700dyne appropriate. Dentistry is the least technically demanding job in oral outpatient care, but many doctors ignore its importance. In order to benefit the interests of patients and health, we should have enough understanding teeth cleaning, careful operation, serious and responsible.
