Antibacterial and Anti-Malodor Efficacy of a Cetylpyridinium Chloride and Zinc Lactate Mouthwash

Fig 1. Short exposure killing of total salivary bacteria by test mouthwashes. Formulas are incubated 1:1 with whole saliva for 30 seconds and then diluted and plated. Results are presented as the log reduction in CFUs/mL relative to a PBS-treated sample.

Fig 2. In vitro biofilm viability after mouthwash treatment. In vitro biofilms were treated with undiluted oral rinses for 30 seconds with remaining biofilm viability measured 2 and 5 hours post treatment through ATP quantification. Percent viability of remaining bacteria in the biofilms was quantified relative to the negative control biofilm group.
