title: [Experimental evaluation of the bacteriotoxic phototherapy of inflammatory diseases of the oral cavity].
abstract: The combined use of laser radiation and Radachlorine revealed the presence of correlation between the number of viable Streptococcus pyogenes cells and the concentration of photosensitizer (r=-0.62), time of irradiation (r=-0.75), as well as energy density (r=-0.80). The death of 100% of suspended S. pyogenes cells was observed at the concentration of Radachlorine reaching 14.4 mM and radiation power reaching 1 W, irrespective of energy density. Pulse and superpulse laser radiation, carried out simultaneously with the use of Radachlorine at a concentration of 1.8 microM, resulted in the death of 100% of S. pyogenes cells in vitro. On the experimental model of inflammation the application of 0.1% Radachlorine gel demonstrated higher effectiveness (in comparison with 0.35% Radachlorine solution) when used simultaneously with laser radiation, both continuous and superpulse (with energy density being 400 j/cm2 and power being 1 W). The use of these parameters in the treatment of the experimental foci of inflammation in the animals led to the complete elimination of S. pyogenes from infected tissues.
