What are the advantages and disadvantages of different scaling methods? Depending on the instruments used, scaling can be divided into manual scaling and ultrasonic scaling. Manual scaling is performed with different types of manual scalers, while ultrasonic scaling is performed with an ultrasonic scaler.
1. Manual cleaning The disadvantage of manual cleaning is obvious, that is, it is time-consuming and labor-intensive. It usually takes about 3 hours to complete the manual scaling of the whole mouth. For patients with a lot of calculus, it even needs to be done in stages. During this process, the patient needs to keep the mouth open.
Opening the mouth for a long time is undoubtedly very uncomfortable for the patient, and the operation for a long time is even more torture for the doctor. Therefore, in clinical practice, manual scaling is used less and less, and ultrasonic scaling is used instead.
However, manual scaling also has its advantages. For doctors, manual scaling feels better and can feel the presence of calculus more clearly. The power of manual cleaning is relatively gentle, and there is no water spray during the operation, so the patient will not have a strong sense of discomfort, and it will also reduce the chance of cross-infection in the clinic.
2. Ultrasonic scaling The ultrasonic scaling machine consists of an ultrasonic generator and a transducer. The generator emits electromagnetic oscillations and amplifies the power. The transducer converts high-frequency electrical energy into ultrasonic vibrations with a vibration frequency of 20,000 to 45,000. Hertz, the calculus attached to the tooth surface is removed by the high frequency oscillation of the working head on the transducer.
The working head of the ultrasonic scaler has various shapes, such as pointed round type and flat type, etc. The suitable working head can be selected according to the size and location of the calculus. also,
There is also a water spray system on the ultrasonic scaler. When the ultrasonic vibration of the working head is started, the water spray system sprays water to the working head at the same time to form aerosol. On the one hand, it plays the role of cooling the working head. acupuncture,
That is to say, there are tiny vacuum bubbles in the sprayed water droplets that collapse rapidly to generate energy, which has a scouring effect on calculus, plaque, etc., and washes away the crushed calculus and blood stains. The advantage of ultrasonic scaling is that it saves time and effort. Generally, the supragingival scaling of the whole mouth can be completed in about an hour.
After ultrasonic scaling, a probe should be used to carefully check for missing calculus. If there are some small calculus and adjacent calculus left, manual instruments should be used to remove them. In addition, some patients are not suitable for application of ultrasonic scaling.
Patients with infectious diseases, such as tuberculosis, hepatitis B antigen positive, HIV infection, etc., are not allowed to use ultrasonic scalers, because the spray produced by it will pollute the operating area and the surrounding environment. Patients with respiratory diseases should not use ultrasonic scalers,
Such as: patients with respiratory depression, patients with chronic lung disease, etc., water spray and spray in ultrasound therapy will bring danger to these patients. Generally, patients who wear a pacemaker are forbidden to use an ultrasonic scaler to avoid symptoms such as arrhythmia caused by interfering with the work of the pacemaker.
