[The effect of zinc chloride mouthwashes on caries-inducing plaque streptococci. 2. In vivo studies of the antibacterial effect of zinc chloride on the total streptococcal flora of the dental plaque].

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 effect of zinc chloride mouthwashes on caries-inducing plaque streptococci. 3. The antibacterial effect of zinc chloride on the species Str. mutans, Str. sanguis and Str. salivarius in dental plaque].

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 the determined initial values.

[The zinc concentration in the dental plaque after zinc chloride mouth rinsing in relation to previous mouth rinsings with different pH values].

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.
