Experts from Penza State University have developed a new way to remove plaque and tartar, which leads to the development of periodontitis, an inflammation of the tissues surrounding the tooth.
One of the main causes of the disease is poor oral hygiene: tartar forms when plaque is not removed. A “pocket” is formed between the tooth and the gum, where bacteria multiply. The most common method of treatment – using a Gracie curette, which replicates the anatomy of the tooth roots – often leads to gingival injury.
The nozzle with an abrasive coating, developed by Russian dentists, completely repeats the anatomy of the teeth and is 3D printed. There are several curette options for each group of teeth – incisors, canines, premolars and molars. This allows you to treat the surface of each tooth under the gums, which was not possible before.
Dental treatment takes place in two stages. In the first, dental deposits are removed, in the second, the root surfaces are polished. After being placed under the gingiva, the nozzle is moved along the root surface at an angle of 10°. When it reaches the bottom of the periodontal pocket, it is treated by adjusting it to 90° angle to the root surface. All grades of nozzle roughness are used consistently – from coarse to very fine.
The procedure allows you to prevent the development of periodontitis or stop its development in the initial stages. The development has passed clinical trials, surpassing all other methods in terms of efficiency.
