FIELD: dentistry.

SUBSTANCE: invention relates to dentistry and can be used in the conservative treatment of initial pulpitis. Soft plaque is removed with an abrasive paste from RDA150-200. The carious cavity is dissected with diamond and carbide borons installed in an air- and water-cooled tip. Hard tissues are treated with a kinetic air-abrasive Rondoflex blaster and a powder with aluminum oxide particles measuring 27 microns. Cofferdam is installed and, at EDI values from 19-25 µA, applications are carried out with an antiseptic 2% aqueous solution of chlorhexidine bigluconate followed by application of tricalcium silicate cement, where cement powder is kneaded in distilled water until a homogeneous mass is obtained, which is distributed linearly or pointwise over the entire surface of the bottom of the hard tissues of the carious cavity, and after hardening of the mass, the carious cavity is treated an adhesive system containing 10 - methacryloyloxydecyl dihydrogen phosphate with super adaptive fluid support. The carious cavity is filled with thermally treated nanocomposite filling material and the tooth surface is finished taking into account occlusion. At the same time, after application of tricalcium silicate cement, the carious cavity is closed with a temporary filling material for final hardening and a temporary bandage is applied, which, after completion of hardening, is removed with a water-cooled ultrasonic nozzle. After treating the tooth surface with a dacron brush using an abrasive paste, a cofferdam insulation system is installed, excess tricalcium silicate cement is removed from the dentin walls with diamond-coated boron and enamel etching is carried out 37% with a solution of orthophosphoric acid for 30 seconds. Then the solution is washed off the enamel with water for 15 seconds, the enamel is dried with an air jet from a paster, a gel based on 5% maleic acid solution is applied to the dentin with rubbing movements of the applicator, the gel is washed off with water for 20 seconds, the surface of hard tissues is dried to a matte shade of enamel and a sparkling shade of dentin, 2% is applied to the surface of dentin an aqueous solution of chlorhexidine bigluconate with an exposure time of 30 seconds, the dentine is dried with air, preventing overdrying and, with an exposure of 15 seconds, a universal adhesive system containing 10-methacryloyloxidecyl dihydrogen phosphate adhesive is applied with an applicator, which is evenly distributed and dried with an air jet until a shiny adhesive film polymerizable on the walls of the carious cavity with an activating lamp for 20 seconds with a luminous flux of 1000 MW/cm. Then, by applying a low-modulus composite material over the entire surface of the dentin, a super adaptive layer with a thickness of no more than 0.5 mm is formed, the layer is polymerized with the light of an activating lamp for 20 seconds with a luminous flux of 1000 MW/cm, a packed composite filling material is layered into the carious cavity, preheated to 55 °C, the shape of the tooth is modeled, and after modeling it is applied a propanediol-based gel is applied to the entire restored surface -1-2-3. Then the gel is polymerized for 30 seconds with a polymerization lamp, the gel is washed off with water for 20 seconds and the restored tooth surface is sanded with diamond-coated finishing borons. Then the excess composite material is removed, the cofferdam is removed, the occlusion is verified, and the restored tooth surface is polished with urethane polyramiabrasiveness of 125, 70, 32 microns. EFECT: method, through the use of tricalcium silicate cement, which contributes to the creation of hermeticism, makes it possible to optimize the regenerative ability of pulp tissues, which improves the quality of treatment of initial pulpitis.
