FIELD: medicine. ^ SUBSTANCE: invention relates to medicine, namely to surgical stomatology and can be used for treatment of chronic periodontitis. For this purpose operative access to teeth roots with root canals which are difficult or impossible to reach, complicated by radicular cyst, is performed. Prepared cavity is processed with constant current of 4-5 mA during 15 minutes through isotonic solution of sodium chloride with trypsinum in ratio 0.1:2 by apparatus "Potok-1". Retrograde filling of root canal is fulfilled with glassionomeric cement "ProRoot". Then it is processed with semi-conductive laser diode, generating pulse light with wave frequency from 0.85 to 0.98 mcm, pulse power 2-4 Watt, pulse duration 40-100 Ns, pulse frequency 1.5-2.0 kHz, magnetic field strength 35 mT during 5 minutes by apparatus "Optodan". After that, it is filled with osteoinducing bioresorbing material "Osteoplast-K" at 2/3 of bone wound, covered with bioresorbing membrane "Paradoncol" and film "Diplen-denta" with metronidasole from oral cavity. The method ensures effective tooth-preserving treatment and reduction of number of post-operative complications due to reliable sterilisation of micro-canals of tooth root and bone wound cavity, obturation, biointegration and angio-osteogenesis, stimulation of osteoreparative process in bone wound, as well as due to preservation of stability and occlusive integration of tooth in tooth arch. ^ EFFECT: increased effectiveness of tooth-preserving treatment in case of chronic periodontitis and reduction of number of post-operative complications. ^ 4 ex, 1 dwg |
