Description

The invention relates to the field of human life support, namely to oral hygiene and toothbrushing.

Compositions for cleaning teeth should include maintaining and maintaining the appearance of teeth by removing stains, plaque and polishing teeth. Cleaning and removal of exogenous plaque prevents carious decay, contributing to the healing of gums.

Polishing tooth enamel provides resistance to ectopic deposition of unwanted components on the surface of the teeth.

A known solution to the patent No. 230692 from 12.22.2005, MKI A61K 8/19, A61Q 11/00. MEDICAL AND PREVENTIVE DENTAL POWDER. Tooth powder contains sodium salt powder of fragmented low molecular weight deoxyribonucleic acid (DNA) with a molecular weight of 150 to 1500 kDa, obtained from the testes of animals and / or their sperm, biologically inert with respect to DNA, abrasive filler, polyvinylpyrrolidone, sodium bicarbonate, flavoring, flavoring and . The components are taken in a specific quantitative content.

The lack of composition is the inability to use in professional oral hygiene using Aire Flow technology.

A known method of maintaining dental hygiene through Air Flow technology is a method of treating teeth with a mixture of sodium bicarbonate powder with water under high pressure.

The method allows painlessly freeing teeth from soft and dense deposits in hard-to-reach places and smooth, polish enamel.

After polishing, the bacteria that cause tooth decay have nothing to catch on. After brushing the teeth, their surface is covered with fluoride varnish.

Advantages are:

the exclusion of mechanical damage to the teeth, since the apparatus feeding the treatment mixture does not come into contact with their surface;

does not affect tooth restoration (fillings);

It has a mild beneficial effect on the teeth, since it is a superficial, gentle cosmetic cleaning, and the chemical composition of the treatment mixture is no worse than toothpaste.

The disadvantages are the inability to create conditions for active remineralization of the teeth and irrational powder consumption due to the mixed size of the fractions.

The solution is known according to patent No. 2580636 dated 12/23/2014, MKI A61K 8/19, A61K 8/25, A61Q 11/00, POWDER COMPOSITION FOR PROFESSIONAL HYGIENE OF THE ORAL CAVITY AND METHOD OF ITS USE.

The powder composition for professional oral hygiene contains sodium bicarbonate, silicon dioxide, and sodium bicarbonate is introduced in an amount of 90-67 weight. %, silicon dioxide is introduced in an amount of 0.5 weight. %, additionally introduced calcium lactate in an amount of 9-32 weight. %, additionally introduced flavoring in an amount of 0.5 weight. % The powder composition is divided into fractions with a particle size of 20-40 and 50-80 microns to remove soft plaque and polish tooth enamel and remove dense plaque.

The disadvantages of the powder composition is the use of silicon dioxide as a disintegrant, which does not completely absorb moisture from the powder composition, which leads to frequent blockages of the nozzle of the device due to low flowability and high friction between the particles of the powder composition and the walls of the nozzle of the device. In addition, the presence of calcium lactate in the wet powder composition leads to premature clumping of the powder composition directly in the nozzle of the device, which further clogs it.

The technical result of obtaining the developed composition is

- increase the flowability of the composition,

- increase in antifriction properties,

- reduction in the time of hygienic cleaning of teeth.

The goal is achieved as follows.

Powder composition for professional oral hygiene and a method for its preparation.

A powder composition for professional oral hygiene, contains sodium bicarbonate, silicon dioxide, a flavor, and sodium bicarbonate is introduced in an amount of 90-75% by weight, the flavor is introduced in an amount of 1.0% by weight,

additionally introduced calcium carbonate in an amount of 25-10% wt.,

additionally introduced hydrophilic silicon dioxide in an amount of 0.05-1.0% wt.,

additionally introduced hydrophobic silicon dioxide in an amount of 0.2-5.0% wt.,

additionally introduced water.

A method of obtaining a powder composition is to obtain a free-flowing, anti-caking, anti-friction composition, moreover, the powder composition is mixed with calcium carbonate, flavor, while rolling particles;

the mixed powder composition is ground in a mill.

The milled powder composition is sieved to a size of 20-50 microns, 50-90 microns and 20-90 microns,

hydrophilic silicon dioxide is introduced into the sieved powder composition in an amount of 0.05-1.0% by weight. and mixed until a homogeneous powder composition,

hydrophobic silicon dioxide is introduced into the mixed powder composition in an amount of 0.2-5.0%) weight. and mixed until a homogeneous powder composition.

the mixed powder composition is sieved on appropriate sieves to remove excess hydrophilic and hydrophobic silicon dioxide,

the mixed powder composition and at the same time water is supplied under pressure through the nozzle of the device to the tooth surface, where sodium bicarbonate mixed with calcium carbonate and silicon dioxide, bombards the surface of the teeth, cleaning them from deposits

The powder composition is prepared as follows.

After grinding the mixed fractions of sodium bicarbonate, calcium carbonate and flavor, sieving the powder composition to the desired size. The required amount of hydrophilic silica is added to the sieved composition. After the introduction of hydrophilic silica, the powder composition is mixed until a homogeneous mass is formed. After that, hydrophobic silica is added to the powder composition and mixed again to form a monoparticular layer. The resulting powder compositions are sieved on appropriate sieves to remove excess silica.

The powder composition is designed and tested.

The resulting powder composition with a particle size of 20-50 microns removes soft plaque and polishes the tooth enamel, performs cleaning of metal structures and bracket systems; a powder composition with a particle size of 50-90 microns removes a dense coating, a coating of a smoker and a coffee lover; powder composition 20-90 microns provides the removal of plaque medium density. The increase in abrasiveness due to the introduction of calcium carbonate reduces the time for hygienic cleaning of teeth. Improved flowability of the powder composition and the antifriction properties imparted to it ensure continuous work of the doctor in the process of professional oral hygiene, without distracting him with the cleaning of Air Flow devices. Separation by fractions ensures the optimal use of powder compositions depending on the nature and characteristics of plaque on the patient's teeth.
