Trial overview
Official title: A Study to Investigate the Antimicrobial Activity of two Test Toothpastes in a Plaque Glycolysis and Regrowth Model
Trial description: The aim of this exploratory study is to assess the ability of two test toothpastes containing 0.6% w/w zinc chloride stabilised with sodium citrate in a sodium lauryl sulfate (SLS)-containing base to reduce glycolytic metabolism and viability of de novo plaquebacteria using the plaque glycolysis regrowth model (PGRM).
Primary purpose:
