[Impedance technique for the determination of the antimicrobial activity of dental materials]. The authors propose a procedure to determine the antimicrobial activity of dental materials, by applying the principles of impedance technology. The procedure is based on the determination of the growth inhibition of test culture microorganisms by the study materials. The following parameters: the type of a test; the parameters of measurement; the qualitative and quantitative composition of culture media; the working cell concentration in the inoculum; the temperature and time of a test, were optimized.
