Description

The utility model relates to the field of medicine and can be used to model the conditions of staining teeth with food drinks containing chromogens (coloring substances).

In dental practice, there are frequent cases of changes in the natural color of teeth, the reasons for which relate to the action of chromogens contained in food drinks and able to remain on the surface of the tooth or in the layer of pellicle adhesively connected to the enamel surface, giving the tooth an unnatural, altered appearance.

Black tea contains a large number of active substances - tannins. Penetrating into the pores of the enamel, they combine with the cells of the dental tissue, giving the teeth a yellowish tint. Coffee contains heavy carbohydrates, cocoa butter and sugar in dangerous amounts for enamel. They are able to penetrate deep into the pores of the enamel, leading to the formation of plaque and the appearance of yellowish-gray pigment spots on the enamel. Natural juices squeezed from dark fruits and berries are rich in phosphoric acid. Under its influence, the upper layer of enamel is destroyed and numerous pores are formed in it. Due to the penetration into the formed gaps of natural pigment substances, which are rich in juices, the teeth acquire a reddish, bluish or other shade, depending on the color of the berries used. Juices from dark berries - blueberries, cherries, blueberries, have the greatest coloring effect.

This design is designed to mix food drinks such as coffee or tea with sugar, as well as to mix any ingredients with liquid. This stirring mug cannot be used to model staining of teeth with food drinks containing chromogens in view of the fact that:

there is no possibility to fix tooth samples so that only the crown part of the tooth is in solution;

you must constantly hold the button so that the electric motor with the screw work, which creates inconvenience in operation;

the location of the propeller blades at an angle of 90 degrees relative to the bottom of the tank does not allow vertical washing with food liquid with the chromogen of the tooth sample.

Currently, to create conditions for staining teeth in an experiment, chemical beakers are used and filled with various coloring agents (http://sintez-lab.ru/catalog/33/109/).

In the article "Laboratory evaluation of the effectiveness of teeth whitening products on model samples based on hydroxylapatite" by I.Ya. Poyurovskaya, E.E. Dyakonenko, [M.E. FIRE STOMATOLOGY 4, 2013 https://www.mediasphera.ru/issues/stomatologiya/2013/4/downloads/en/030039-1735201341] describes the simulation of staining with a food drink with a pronounced staining ability of dental products based on hydroxylapatite (HAP). The choice of dental products based on hydroxylapatite is justified by the authors of the article because of the proximity of this material to hard tooth tissues. Tea was used as a food product with pronounced coloring ability. To prepare the staining medium, distilled water was heated to boiling in a heat-resistant beaker. Tea was placed in boiling water (Brooke Bond, black leaf leaf; 1 liter of water - 10 g of tea) and boiled for 5 minutes; the solution was cooled to room temperature and filtered. HAP samples were stained by immersion and soaking in tea extract for 24 hours at a temperature of 37 ° C. HAP control samples were kept in distilled water. The quantitative assessment of the color of model samples was carried out on a Spectron-M color analyzer (Sigma-Optic CJSC, GOST 51202-98).

As a prototype, we chose a heat-resistant chemical beaker described in this article.

The disadvantages of the above analogues, as well as the prototype include the lack of the ability to create the same conditions for the impact of food drinks containing chromogens on tooth samples, as in the human oral cavity, due to:

the absence in the tank of constantly circulating in the vertical and horizontal directions of the flow of the investigated food drink containing chromogens, which leads to the formation of sediment, and thus, the uniformity of the environment of the above food drink changes, and within a few hours the concentration of the initial solution of the food drink containing chromogens increases that affects the reliability of the result;

the lack of a system for fixing tooth samples, which does not allow creating conditions under which only the crown part of the sample / tooth samples / teeth would be in a food drink containing chromogens;

lack of connection to an external voltage source, which limits the ability to use the device without ensuring its stable operation.

The technical result of the utility model is to expand the arsenal of tools designed to simulate tooth staining with food drinks containing chromogens, as well as ensuring stable operation of the device, creating a flow of the studied food drink containing chromogens constantly circulating in the vertical and horizontal directions, and providing the possibility of fixing tooth samples so that only the crown of the tooth is in solution, which will allow the creation of the same conditions the effects of food drinks containing chromogens on tooth samples, as in the human oral cavity.

The technical result of the utility model is achieved in that the device for modeling tooth staining with food drinks containing chromogens is a container equipped with a lid in which openings are made. Cofferdams with holes made in it, arranged in accordance with the location of the holes on the cover, are tensioned and fixed using glue. The diameter of each hole in the cofferdam is less than the diameter of the hole in the lid and less than the average diameter of the neck of the tooth. For samples 16, 17, 18, 26, 27, 28, 36, 37, 38, 46, 47, 48 teeth, the diameter of the holes is 11 mm, for samples 11, 21 teeth - 9 mm, for samples 12, 22, 31, 32, 41, 42 teeth - 6 mm, for samples 13, 23 teeth - 8.5 mm and for samples 33, 43 teeth - 7.5 mm. In the middle of the bottom of the tank, a screw is rigidly fixed with the blades inclined relative to the bottom of the tank at an angle of 45 degrees, connected to the axis of the electric motor located on the base of the tank and connected to the power source via an electric wire through the on / off switch.

In FIG. 1-5 presents the inventive device for modeling tooth staining with food drinks containing chromogens, where:

1 - capacity;

2 - cover;

3 - holes in the cover;

4 - holes cofferdam;

5 - switch / switch;

6 - electric wire;

7 - electric motor;

8 - bottom of the tank;

9 - screw;

10 - axis of the electric motor.

The utility model works as follows:

A food drink containing a chromogen, for example tea, is poured into the container (1). After that, the container is closed with a lid (2), in which there are 10 holes (3), above each of which there are 10 holes of cofferdam (4), in which the sample / samples of the tooth / teeth necessary for examination are fixed. The tooth sample / teeth are inserted into the hole (s) of the cofferdam (4) and fixed with a cofferdam so that only the crown part of the tooth sample / samples protrudes and is in the food drink containing the chromogen from the hole (s) (3) / teeth. Then, using the on / off switch (5) located on the electric wire (6), turn on the electric motor (7), which is located on the bottom of the tank (8) and creates fluid movement in it, the electric motor (7), due to the connection with the screw ( 9), through the axis of the electric motor (10), it moves a solution of a food drink containing chromogen, which for a long time washes in two directions the crown part of the tooth / tooth samples until the switch on / off is turned off (5 ) After staining, remove the lid (2) with the sample / samples by tooth / teeth, wash the container (1) and take out the sample / samples of the tooth / teeth to assess the degree of staining of its tissues.

Distinctive essential features and a causal relationship between them and the achieved technical result.

A device for modeling tooth staining with food drinks containing chromogens is a container equipped with a lid, with the help of which a tooth sample is fixed.

Holes are made in the cover. Cofferdams with holes made in it, arranged in accordance with the location of the holes on the cover, are tensioned and fixed using glue. The diameter of the hole in the cofferdam is smaller than the diameter of the hole in the lid and smaller than the average diameter of the neck of the tooth, due to this, as well as the elastic properties of the cofferdam, the teeth are fixed so that only the crown of the tooth is in solution, which allows creating the same exposure conditions for food drinks containing chromogens, on tooth samples, as in the human oral cavity.

The diameter of the holes in the lid has certain dimensions indicated in the formula, which correspond to the average diameter of the equator of a tooth of a certain group affiliation.

In the middle of the bottom of the container, a screw is rigidly fixed with the blades inclined relative to the bottom of the container at an angle of 45 degrees, which ensures not only horizontal washing of the tooth sample, but also vertical due to the fact that when the screw rotates, a food drink containing chromogen between the bottom of the container and the screw rises up, thereby creating a vertical washing of the tooth.

The screw is connected to the axis of the electric motor, which is located on the base of the tank and, in turn, connected to the power source through an electric wire through the on / off switch, which ensures the rotation of the screw, which creates a constantly circulating flow of liquid (food drink containing chromogen) in capacity, which does not lead to the formation of sediment, and thus, does not change the uniformity of the environment of the food drink.

The on / off switch activates the electric motor by connecting the power source to the electric motor.

The ability to connect to an external voltage source ensures stable operation of the device.

The utility model has been successfully tested on the basis of the Dental Clinic "Pearl" (Veliky Novgorod).

The inventive utility model expands the arsenal of tools designed to simulate staining teeth with food drinks containing chromogens, and also, unlike the prototype, ensures stable operation of the device, allows you to create a constantly circulating in the vertical and horizontal directions, the flow of the studied food drink containing chromogens, and provides the ability to fix tooth samples so that only the crown of the tooth is in a solution of a food drink, which allows you to create Which same exposure conditions nutritional beverages containing chromogens, on the tooth samples in the oral cavity of man.
