Abstract
Knowing antiseptic activity of chemical disinfectant substances and their use in stomatological practice has a great practical value. It is evidential that there is the need for defining standard technique for quantitative determination of bactericidal activity of chemical disinfectant substances. Solution of phenol (5%) was considered as referent standard for evaluation of efficacy of disinfectant aqueous solutions. On the other side the methods for evaluation of

ABSTRACT BOOK
antiseptic activity of disinfectant aqueous solutions are microbiological.The aim of this study is to develop a new empirical coefficient which is capable to express the various physicochemical properties of disinfectant solutions on bactericidal activity. This parameter (Disinfection Activity Coefficient of Solution - DACS) has to express capability for comparison and prediction of disinfectant activity. The DACS index, which is the sum of four terms (fluidity, surface tension, redox potential and osmolality) is in good correlation with the activity at different disinfectant aqueous solutions. The DACS index can be calculated using additive and statistical models. Statistical model is adequate for evaluation of different disinfectant solutions because of better expressing the bactericidal activity then additive model. For analyze of various dilutions of one disinfectant there is no significant difference between this two models. The usefulness of DACS is demonstrated for analyze of bactericidal activities on different disinfectant solutions containing boric acid, chlorhexidne, chlorhexidine with cetrimide, chloroxylenol, chlorophen, eosin, hydrogen peroxide, phenyl mercury borate, povidon-iodine, thiomersal, tosilchloramide and phenol. Results for bactericidal activities obtained from microbiological tests on Staphylococcus aureus were compared with activities predicted by DACS. As the conclusion, it is considered good correlation between experimental and calculated values for bactericidal activity.Key words: disinfectant, bactericidal activity, antiseptic
