During a 14-day test period a 0.2% and a 0.4% zinc chloride solution have been examined concerning their antibacterial efficiency on the total streptococcus flora of dental plaque under conditions conforming to standard by means of the Mylar foil technique. The results of the microbiological examination show a significant decrease of colony developing units(More)
The quantitative behaviour of Streptococcus mutans, Streptococcus sanguis and Streptococcus salivarius has been examined in initial findings and after application of 0.4% zinc chloride solution. After a 7 day rinsing the number of colony developing units of the species Streptococcus mutans and Streptococcus sanguis in the plaque decreased to about 30% of(More)
The antimicrobial efficiency of zinc chloride solution in concentration from 0.1% to 2.0% and 0.2% chlorhexidine solution has been examined on the strains of reference in a comparative study. Three test methods were applied: the agar diffusion test, the dilution test and the suspension test. As was to be expected the antibacterial effect of the zinc(More)
The zinc content in dental plaque after mouth rinsing with 0.2% zinc chloride solution is dependent on previous mouth rinsing with different pH value. Zinc retention is strongly reduced by rinsing with citric acid solution (pH value 1.0). Zinc retention is growing with increasing pH value when rinsing was made with sodium citrate buffer solution with(More)
