Penetration of Plaque Bacteria
LISTERINE® penetrates plaque bacteria effectively1
Representative images of biofilm after 48 hours.
Untreated (negative control)
From left to right: Sagittal extended focus top down (growth surface on left), birds' eye view extended focus, 3D top view, 3D bottom view. Live bacteria are shown in green and dead bacteria in red.
LISTERINE® Coolmint treated biofilm
The visual results highlight the depth of penetration by LISTERINE® Coolmint showing more dead organisms throughout the biofilm after treatment.
