A rapid method for evaluating microbicidal activity of dentifrice formulations against salivary bacteria ex vivo.


A new rapid ex vivo method was developed for evaluating the short-term bactericidal activity of dentifrices against salivary microorganisms. Dentifrice aliquots of 0.25 or 1.0 g were rapidly dispersed into 3.5 mL of freshly pooled human saliva, and 1.0 mL aliquots of the dentifrice-saliva suspension were collected after 30 or 60 seconds of exposure, diluted… (More)
