Operation and interpretation skills of ultrasonic cleaning

1. Introduction to Ultrasonic Cleansing

1. Ultrasonic cleansing is the most effective way to remove plaque and calculus on the gums. It eliminates the irritation of plaque and calculus, and can make gum inflammation completely subsided or significantly reduced.

2. The ultrasonic scaler is composed of an ultrasonic generator (host) and a transducer (mobile phone). The host oscillates and converts it into ultrasonic vibration, causing the cutter head to vibrate 25,000 to 30,000 times per second, thereby shattering the tartar and the cutter head. The attached water spray cools the cutter head on the one hand, and washes away the shattered tartar and blood on the other.

3. According to the performance and working principle, the transducer in the mobile phone can be divided into piezoelectric ceramic type and magnetic sound lock type. Piezoelectric ceramic type power is 7W, life span is 1-2 years, it is painful when used, and the price is low. Magnetic sound lock type power 16W, life of 6-10 years, expensive, such as imported machines such as Dentsply.

4. Some scalers are equipped with sandblasting function. The high-speed quartz sand sprayed by the mobile phone can whiten the tooth surface and play a role in polishing, but sandblasting will cause scratches on the tooth surface and sometimes damage the gums.

5. In general, the correct technical operation will not cause tooth damage. It can be observed under the scanning electron microscope that finer nicks can be formed on the enamel after tooth washing. Generally, it is caused by the remineralization of saliva after 1-2 weeks. Completely repaired,

6. Ultrasonic cleansing is forbidden for patients with pacemakers. It is used with caution for patients with infectious diseases such as hepatitis and tuberculosis. Ordinary blades are prohibited for dental implants.


2. Operation method

1. Oral health education: main explanation:

(1) Why wash your teeth

(2) The benefits of washing teeth

(3) Problems caused by washing teeth.

2. Check the oral health: after the explanation, it is recommended that the patient use an imported machine or a domestic machine.

3. Check the machine: pressurize the water tank, whether it is energized, knife head, bra, mouthwash, conventional disposable treatment tray, and saliva suction device.

4. Test machine: After stepping on the foot switch, water mist sprayed from the cutter head. The water volume of the imported machine is slightly larger than that of the domestic machine, which can reach 35ml/min. At this time, the temperature of the cutter head is 40 degrees Celsius, and the power should not be too high at the beginning. If the power is too large, the cutter head is easy to wear and the pain is strong.

5. Special mouthwash for 60 seconds


6. The cleansing usually starts from the posterior teeth. Because of the low irritation of the posterior teeth and the strong irritation of the anterior teeth, it is easy for patients to accept it. Note when cleaning:

(1) The mobile phone should be operated with a pen;

(2) Try to use the ring finger or little finger of the right hand to form a fulcrum on the patient's face during operation;

(3) The cutter head should be parallel to the tooth surface or move back and forth under the tartar contacting the tooth surface at an angle of less than 15 degrees, and use ultrasonic vibration to shake and break the tartar;

(4) When removing large and hard supragingival calculus, the segmentation method can be used to divide the large calculus into several pieces to remove or place the cutter head on the edge of the joint between the calculus and the tooth surface to vibrate to separate the calculus from the tooth surface. Shattered.

(5) When removing the tartar with the cutter head, the force should be light. The method of moving the cutter head back and forth should not stay at a point and vibrate, which will cause damage to the tooth surface.

7. Postoperative examination: After cleansing, use a probe to check whether there is any remaining calculus. For some small or adjacent calculus, use hand instruments to supplement the scraping.

8. Polishing: Put the rubber cup wheel on the elbow head of the slow-speed mobile phone and rotate at low speed. Dip polishing paste or toothpaste to polish the tooth surface. You can apply a little pressure to make the thin edge of the rubber cup extend under the gingival margin. The conical rubber polishing wheel can be used for polishing the parts that are not easy to polish in the adjacent gap.

9. Apply iodine glycerin to local gums

10. During the cleansing operation, pay attention to timely communication with the patient. At least 5-10 minutes should be reminded of the patient such as gargle, saliva, and active position. They should not be silent for a long time and bow their heads and just focus on the operation. Especially when cleaning the front teeth, the patient may feel a little discomfort. Relevant matters should be explained in time after the operation. If you should wash your teeth again after six months to one year, if you feel uncomfortable, it will automatically disappear within 1-2 weeks. The second cleansing date for imported models will be called for an appointment.


Three, related interpretation issues

1. Why wash your teeth? What are the benefits of washing your teeth?

Teeth cleaning is a popular term for ultrasonic cleansing. It is not a method of whitening teeth like a bath, but a method of using an ultrasonic machine to remove calculi and pigments that are not applied to the surface of the teeth. Mainly "washing" rather than "washing white".

In the process of human growth, after children enter adults, the adhesion of food residues and the deposition of calcifications in saliva can form calculus on the neck of the teeth. For people with irregular teeth, dentures and poor oral hygiene, calculus Especially powerful. Some people find that tartar grows faster after washing their teeth (love the mouth), which is mainly related to the failure of strict polishing after the tooth washing, because after removing the tartar, the contact part of the tooth and the tartar is obviously rough. If not strictly polished, it will be rough. Naturally, it is easier to deposit calculus on the surface,

Rough tartar and its adsorbed bacterial toxins will directly stimulate the inflammation of the gums. In the early stage, it can be manifested as bad mouth smell, bleeding from brushing, sometimes brown or black stones attached to the neck of the tooth, and the gums are dark red with slight swelling. After cleaning the teeth, the cause of gum inflammation is removed, and the above symptoms will usually disappear naturally. If tartar exists for a long time, the inflammation of the gums will further develop into periodontitis, manifested by periodontal pus, obvious pain, loose teeth, and atrophy of gums, until the teeth fall out. At the same time, tooth loss due to periodontitis is often accompanied by the resorption of periodontal alveolar bone, just as tree extraction is accompanied by the loss of root soil, which will cause the difficulty of implanting dentures.

Therefore, washing teeth is a preventive health care measure that adults should have, and washing teeth 1-2 times a year is a common practice for dental health care.

2. Does the toothache hurt? Does it damage the teeth?

Perform correct technical operations. For example, the strength of the ultrasonic scaler is moderate, the cutter head is parallel to the tooth surface or at an angle of 10-15 degrees instead of perpendicular to the tooth surface, and the cutter head does not stay at a point for a long period of time. For teeth, it will definitely not cause any pain or discomfort. Even if it occasionally causes fine teeth that can only be seen under a microscope, it will be completely restored to normal within 1-2 weeks under the remineralization of calcium phosphate in the saliva. . Therefore, washing teeth is a completely harmless method of dental health care.

However, in actual situations, discomfort and soreness after washing teeth often occur, and the reasons are roughly as follows:

(1) Related to tooth anatomy: 10% of normal teeth do not touch each other with enamel and pulp in the tooth neck, which leads to exposure of the dentin of the tooth neck. Normally, there is no obvious discomfort when the dental calculus is attached here, but the dental calculus is removed. The strong vibration at time directly stimulates the dentin, causing discomfort and soreness.

(2) Incorrect operation: For example, the intensity is too high, the water mist is too small, the angle is not right, the cutter head stays in one place for a long time, etc.

The discomfort and soreness of teeth cleaning will generally be completely recovered within 1-2 weeks due to saliva remineralization. Using our hospital's desensitizing gel will speed up the recovery process.


3. Why is your outpatient dental cleaning expensive and what are the characteristics of the dental cleaning?

(1) We are a professional dental treatment institution that performs standardized cleansing procedures, which seem to be more expensive, but actually worth the money

(2) Scaling doctors have received strict training and assessment of cleansing operation techniques.

(3) Ultrasonic scalers are reliable in quality and highly targeted. We will recommend different types of machines for dental calculus and periodontal conditions. Domestic scalers can be selected for those with less calculus and less gingival inflammation, with more calculus and gums. For severe inflammation, it is recommended to use imported scaler and perform second cleansing to achieve perfect results.

(4) Strict disinfection: The blades of the scaler are strictly disinfected. If required, disposable blades can be selected. In order to avoid aggravation of gum inflammation during operation, use a special antibacterial mouthwash before the operation to rinse the gums after the cleansing is completed. Apply antibacterial and anti-inflammatory drug-iodine glycerin, which can stay in the local area for half an hour and continue to work.

(5) Technical operation specifications, completely remove calculus, while reducing the damage to the gums to a minimum. The precise and efficient polishing greatly prolongs the reattachment of dental calculus and reduces the number of teeth cleaning.
