Efficacy and role of estazolam tablets

Dental scaler is a kind of scaling device in the oral treatment device, which belongs to Class I medical device. Dental scalers usually consist of a handle, working end, and working blade, and are held in a modified pen style. It is generally made of stainless steel and provided non-sterile.

It is mainly used to remove tartar on the tooth surface or to pick, dig, scrape and other operations on tissues or materials in the process of oral treatment. The curettage is divided into spoon type, hoe type and file type. Spoon-type curators can be divided into general-purpose curators, Gracey curators and Mini curators.

Universal scaler, can scale all surfaces of a tooth, both ends can be used. The Gracey scaler is divided according to the tooth position and tooth surface to be scaled. The ideal instrument, its working edge can only be used on one side, and it is the most clinically used scaler.

MINI scaler, which is used for narrow and deep periodontal pockets, with less trauma and quicker healing time during clinical operations, so that patients will feel more comfortable. Because of the need to operate in a narrow and deep periodontal pocket, the working end of the MINI scaler is longer, smaller, and more expensive than the Gracey scaler, requiring several hundred pieces.

Clinical use of scaler is to use the feel to sense and scrape the root surface diseased tissue and scattered calculus and plaque, so that the root surface is smooth, which is conducive to the re-attachment of the gums to the root surface, eliminating Periodontal pockets.

Are scales harmful to teeth?

The main culprits of periodontitis are calculus and plaque, especially in the periodontal pockets. Tooth scaling is to use a special dental scaler to scale some calculus and plaque on the periodontal. Therefore, the dental scaler is not harmful to the teeth, but the correct choice of the scaler is necessary. If the wrong choice is made, it will easily cause damage to the patient’s gingival tissue and dental tissue. Let’s take the Gracey scaler as an example, it has a total of 9 pieces:

No.1/2 is used for anterior subgingival and subgingival

No.3/4 is used for anterior gum Inferior and apical subgingival

Size 5/6 for subgingival and subgingival premolar

Size 7/8 for subgingival premolar and buccal and lingual of molars Subgingival

size 9/10 for buccal and lingual subgingival of molars

size 11/12 for mesial subgingival of posterior teeth

< p>Size 13/14 is used for distal subgingival of posterior teeth

Size 15/16 is used for mesial subgingival of posterior teeth

Size 17/18 is used for posterior teeth Distal subgingival

Common cure methods

1, cure time

Subgingival scaling, usually a supragingival scaling, which is 1 week after ultrasonic scaling.

Steps of scaling

(1) Probe the depth of the periodontal pocket with a periodontal probe, and then probe the subgingival calculus with a sharp probe to determine its size and location.

(2) Disinfect the operation area with 1% iodine tincture, including gingiva, tooth surface and periodontal pocket.

(3) According to the distribution of subgingival calculus, it is divided and treated in stages. When doing full-mouth scaling, it is often started from the distal end of the last molar, followed by the buccal surface to the mesial surface, and the scaling is performed forward by tooth.

(4) First, use a subgingival hoe-type scaler to remove larger calculus, and then use a spoon-type scaler or a file-type scaler to remove smaller subgingival calculus, and the teeth will be polished. noodle. After the buccal surface is done, the tongue surface is done again, and other areas are also scraped in order.

(5) During scaling or after scaling, a sharp probe must be used to carefully check whether the subgingival calculus is removed and whether the root surface is smooth, so as to decide whether scaling is necessary.

(6) After flushing the operation area with normal saline or 3% hydrogen peroxide solution, apply 1% iodine tincture or 2% iodine glycerin.

Is hand scraping clean and hygienic?

There are generally two types of subgingival scaling, ultrasonic scaling and manual scaling. Ultrasonic scaling is faster and more efficient. In terms of the cleanliness of scraping, manual scraping is generally cleaner than ultrasonic scraping. Because the doctor can really feel the presence of calculus during manual scaling, the scraping is cleaner.

Especially for patients with severe periodontitis who have a lot of dental calculus, the doctor needs to cooperate with manual scaling to remove the missing parts after ultrasonic scaling. However, neither ultrasound nor manual scaling can completely remove the infectious substances and pathogenic bacteria in the periodontal pocket, which is one of the reasons for the high recurrence and refractory periodontal disease.

Can scaling damage my gums?

Many patients are afraid to do subgingival scaling for fear of damaging their gums. Subgingival scaling is an important means of periodontal treatment, which plays an active and essential role in the treatment of periodontitis. Because subgingival scaling is a complex and delicate work, the technical level of the doctor is very high. Scaling and treatment transmitted on the Internet will damage the gums, which may be caused by the limited technical level of the doctor and the non-compliant operation.

In summary, subgingival scaling is very important for the treatment of periodontitis. Don’t be afraid of the disease, and don’t believe too much in online rumors. Choose a regular hospital and a professional doctor to formulate an ideal treatment plan. , restore healthy gums.
