Description

The utility model relates to medical technology, namely, medical instruments for collecting the contents of the gingival groove and periodontal pocket for the purpose of microbiological research.

Known cellophane disc for collecting the contents of the periodontal pocket, consisting of a cellophane film 40 μm thick, 6 mm in diameter, which is introduced into the periodontal pocket using a button-like probe [1]. When inserting and removing the disc from the periodontal pocket, it is possible to attach the microflora of the supragingival dental deposits and the microflora located on the probe, which will significantly reduce the quality of the sample obtained.

Known tool for taking a sample of the contents of the periodontal pocket and / or the periodontal sulcus. The working part is a hollow spatula equipped with a bent hollow single-use rod with a calibrated volume, ending in a slotted hole along the entire width, the opposite end of the rod is equipped with a cone-shaped tip that is fitted with an interference fit on the syringe cannula with a volume of not more than 2 cm ³ [2]. The disadvantage of the tool is that it has a complex design, does not allow collecting the contents from the walls and bottom of the periodontal pocket, which significantly reduces the quality of the sample obtained.

Known paper pin for collecting samples from the periodontal pocket, size No. 25 [3]. The disadvantage is its softness and flexibility, which prevents high-quality sampling from the walls and bottom of the periodontal pocket. The post is capable of absorbing liquid, and therefore part of the test material with microorganisms remains inside the post, which complicates the inoculation of the material and distorts the test results.

Known tool for taking the contents of the periodontal pocket, having a handle; a body that bends at an angle of 150 °, passing into the working part at an angle of 60 °. On the working part, bristles up to 0.4 mm long are located in a spiral above the atraumatic tip at an angle of 45 °; at a distance of 4 mm and 6 mm from the atraumatic tip, colored marks are applied to the working part; the notch for separating the working part is located under the thread that serves to connect with the protective cap [4]. This device is taken as a prototype.

The disadvantage of the tool is that the bristles on its working part are arranged in a spiral, which makes it difficult to use the tool for collecting content from the gingival groove; when separating the working part of the instrument from the body, it is necessary to perform additional manipulations in the form of cutting it off, which can lead to contamination of the biological material, distortion of the results of microbiological research.

The technical result of the utility model is the creation of an instrument for collecting the contents of the gingival groove and periodontal pocket.

This goal is achieved by the fact that the handle and the hollow body are made of medical steel; the distal part of the hollow body is bent at an angle of 150 ° and has a hole with an internal thread corresponding to the external thread of the screw for fixing a disposable working part in the body, which has an additional color mark at a distance of 2 mm from its atraumatic tip and bristles located longitudinally on both sides.

The handle and the hollow body of the instrument are made of medical grade steel. They can be disinfected and sterilized, which allows them to be reused. The bends of the body and the working part make it possible to conveniently insert the instrument into the oral cavity and directly into the gingival groove and periodontal pocket. The screw allows you to securely fix the disposable working part in the distal part of the hollow body. The working part of the instrument is disposable, which reduces the risk of infection of the patient, improves the quality of microbiological examination and allows it to be safely disposed of.

The longitudinal bilateral arrangement of the bristles on the working part, in contrast to the spiral arrangement, allows the instrument to be inserted not only into the periodontal pocket, but also into the gingival groove, the width of which, in a healthy periodontium, is 0.5 mm. All this as a whole makes it possible to expand the range of studies.

The presence of an additional colored mark at a distance of 2 mm from the atraumatic tip of the working part allows the instrument to be inserted into the gingival groove without injuring the periodontal ligament of the tooth. The depth of the gingival groove in a healthy periodontium is 2 mm [6].

A tool for collecting the contents of the gingival groove and periodontal pocket, consisting of a ribbed handle, a body and a working part that is curved at an angle of 60 °, has bristles up to 0.4 mm long, located at an angle of 45 °, and colored marks on both sides at a distance of 4 mm and 6 mm from the atraumatic tip, characterized in that the handle and the hollow body are made of medical steel; the distal part of the hollow body is bent at an angle of 150 ° and has a hole with an internal thread corresponding to the external thread of the screw for fixing a disposable working part in the body, which has an additional color mark at a distance of 2 mm from its atraumatic tip and bristles located longitudinally on both sides.

The utility model is illustrated by graphic material. Figure 1 shows a tool consisting of a handle 1, a body 2, a screw 3 for fixing the working part 4 with an atraumatic tip 5, a longitudinal bilateral arrangement of bristles 6 and three colored marks 7.

The tool is used as follows. The disposable working part is fixed with a screw in the hollow body. The collection of material is carried out in the morning on an empty stomach, before the procedure for brushing your teeth. The examined teeth are cleaned with a cotton swab without using antiseptic solutions and are isolated from saliva. The instrument, without touching other surfaces, is inserted into the gingival groove of the studied tooth parallel to its axis. When the instrument is inserted, the bristles do not damage the walls of the gingival groove. The depth of its immersion is controlled by the distal mark of the working part located at a distance of 2 mm from its atraumatic tip. After removing the instrument from the oral cavity, the screw is unscrewed, the disposable working part with the contents is placed in a sterile test tube and sent for examination. In a similar way, the contents of the periodontal pocket are taken. In this case, the tool is inserted into the pocket of the tooth under study parallel to its axis. The depth of its immersion is monitored and the depth of the periodontal pocket is measured using two proximal marks of the working part located at a distance of 4 mm and 6 mm from the atraumatic tip.

The use of the tool is illustrated by clinical examples:

Patient B., 27 years old, was sampled the contents of the gingival groove using the developed instrument. The atraumatic tip of the working part of the instrument was easily inserted into the gingival groove with immersion to the level of the color mark of 2 mm. The contents of the gingival groove were taken, the instrument was removed from the oral cavity, the screw was unscrewed, the working part of the instrument was placed in a sterile test tube and sent for examination. After microbiological examination, the working part of the instrument was disposed of.

Patient S., 45 years old, was taken from the contents of the periodontal pocket using the developed instrument. The atraumatic tip of the working part of the instrument was easily inserted into the periodontal pocket with the immersion of the working part to the level of the 6 mm color mark. The contents of the periodontal pocket were taken, the instrument was removed from the oral cavity, the screw was unscrewed, the working part was placed in a sterile test tube and sent for examination. After microbiological examination, the working part of the instrument was disposed of.

The instrument for collecting the contents of the gingival groove and periodontal pocket can be used in the practice of a dentist in dental clinics and hospitals for the purpose of microbiological research.
