Description	We measured the growth of yeasts Saccharomyces cerevisiae on mercury electrode. We use measurement of differential capacitance, time dependence and impedance spectroscopy. We were able to control growth of microorganisms in broth on solid electrode. We detected the forming of biofilm on mercury surface and we were able to detemine the concentration of microorganisms in broth.The adhesion of model microorganisms Streptococcus mitis and Streptococcus salivarius present in oral plaque to the polymer component of dental restoratives was studied. The composition of dental restoratives was varied, thus influencing their hydrophobicity. Polymers are the some of the most commonly used biomaterials in dentistry due to the compatibility of their mechanical viscoelastic properties with human tissues. Resin composites with antibacterial activity may be useful to decrease the frequency of secondary caries around restorations.
