[The microorganism count on impression materials following disinfection by dynamic plasma treatment]

B. subtilis and B. cereus in concentrations under 10(5) mt, and of E. coli M-17 below 10(7) mt on different plaster materials die within fractures of a second after dynamic plasma processing at atmospheric pressure and at least one passing of the processed surface at a rate of 2.0 to 2.5 m/s at plasma flow power of 60 kw.
