METHOD OF TREATMENT OF DENTAL CARIES Russian patent published in 2024 - IPC A61C5/00 A61K6/00 A61K8/34 A61K31/65 A61P1/02 

FIELD: dentistry.

SUBSTANCE: invention relates to dentistry and can be used in the treatment of dental caries. Soft plaque is removed from the tooth surface within 60 seconds with an abrasive paste based on silicon dioxide and zirconium silicate, the carious cavity is opened with a spherical boron with a diameter of 1.2 mm with a diamond coating and blue marking installed in an air-cooled turbine tip. The carious cavity is expanded with a fissure boron with a diameter of 1.2 mm with a diamond coating with blue markings, which replaces the spherical boron in the turbine tip. Necrectomy is performed with an angular tip with air-water cooling using a carbide spherical boron with a diameter of 1.2 mm or 1.4 mm. Necrectomy is checked by probing, in which dense dentin is attached and the probe slides over the surface of the dentin. A carious cavity is formed with a fissure boron with a diameter of 1.2 mm with a diamond coating with a red marking installed in the turbine tip is used to finish the edges of the enamel with carbide octahedral finishers with a red marking, kinetic preparation of a carious defect is carried out at a distance of two millimeters from the tooth surface with a Rondoflex blaster and powder with aluminum oxide particles of 27 microns in size, air-abrasive treatment of the surface of hard tissues is carried out for 15 seconds. The working field is insulated with a latex curtain, the surface of hard tissues is washed off with water for 5 seconds, the enamel is dried with an air jet from a paster for 5 seconds, a gel based on a 37% solution of orthophosphoric acid with dynamic activation is applied to the enamel for 30 seconds, the gel is washed off the enamel with water for 15 seconds, and the enamel is dried an air jet from a puster. Then on dentin a gel based on a 5% maleic acid solution is applied and with rubbing movements with an Extrafine applicator with a diameter of 1 mm, the gel is distributed over the dentin surface for 20 seconds, the gel is washed off with water for 20 seconds, the surface of hard tissues is dried, preventing the dentin from drying out. A 2% aqueous solution of chlorhexidine bigluconate is applied to the dentin surface with an exposure time of 30 seconds, the applied aqueous solution is dried with air, preventing overdrying of the dentin, with an exposure of 15 seconds, a double application of a universal adhesive system containing 10-methacryloyloxidecyl dihydrogen phosphate is carried out, the adhesive is evenly distributed along the walls of the carious cavity, while the second portion of the adhesive is applied before drying and polymerization of the first portion with rubbing movements to improve penetration the adhesive is applied to the dentin, then the adhesive system is distributed and dried with an air jet, polymerized with the light of an activating lamp for 20 seconds and with a luminous flux of 1000 mW/cm, a low-modulus composite material is applied over the entire surface of the dentin to form a superadaptation layer with a thickness of not more than 0.5 mm, the formed layer is polymerized with the light of an activating lamp for 20 seconds and with a luminous flux of 1000 mW/cm. A preheated composite filling material preheated to 55 °C is layered into the carious cavity, adapted using a modeling resin and polymerized, enamel layers of selected shades are lapped to the surface of hard tissues and polymerized, a propanediol-based gel is applied to the entire surface-1-2-3 which is polymerized within 30 seconds using a polymerization lamp, the gel is washed off with water for 20 seconds, the surface of the restoration is sanded with diamond-coated finishing borons, excess composite material is removed, the insulation system is removed, occlusion is verified with successive application of articulation paper with a thickness of 40 microns and 8 microns, respectively, and then the tooth surface is polished with diamond heads, discs, brushes and pastes.

EFFECT: method, by improving the adhesion of the composite filling material to the hard tissues of the tooth, ensures the durability of the restoration.
