METHOD FOR TREATMENT OF DESTRUCTIVE CHRONIC PERIODONTITIS USING INJECTION FORM OF AUTOLOGICAL PLATELET PLASMA Russian patent published in 2017 - IPC A61K35/16 A61P1/02 

FIELD: medicine.

SUBSTANCE: method includes instrumental processing using rotor instruments with an extension of the apical part of the channel to a diameter of at least 025 ar per ISO, conicity of at least 4%, drug treatment of the dental canals with passive ultrasonic irrigation and canal drying, temporary obturation of canals with calcium hydroxide with sealing under glass ionomer cement, general drug therapy. Drug treatment is carried out with a 17% solution of ethylenediaminetetraacetate and 1.5% sodium hypochlorite solution, after 12-24 hours after calcium hydroxide repfreshing, injections of platelet autoplasma (PAP) are made into soft tissues in the fistula area, if present, submucosally in the transitional fold, subperiosteally in the projection of the apexes involved in the pathological process of roots from the vestibular or palatal, lingual surfaces. At that, calcium hydroxide refreshing and PAP injection the root canals are carried out once or 2-3 times with an interval of 7-10 days, then canal obturation is effected by lateral or vertical condensation of gutta-percha and the epoxide-amine resin-based sealer.

EFFECT: use of the invention provides relief of acute inflammatory process, reduction of treatment time, stimulation of bone tissue regeneration and replacement of a defect in a chronic inflammation focus by accelerating natural mechanisms of tissue regeneration due to platelet-derived growth factors.
