Official Title: A Study to Investigate the Antimicrobial Activity of Two Test Toothpastes in a Plaque Glycolysis and Regrowth Model

Brief Summary: 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 plaque bacteria using the plaque glycolysis regrowth model (PGRM).

Detailed Summary:
Sponsor: GlaxoSmithKline

Current Primary Outcome: Area Under the Curve for Glycolysis (AUCgly(0-90)) of Test Zinc-IPMP and Non-SLS Negative Control [ Time Frame: Baseline up to 90 minutes (min) ]

AUCgly(0-90) of Test zinc-IPMP and non-SLS negative control was calculated using trapezoidal method.


Original Primary Outcome: Same as current

Current Secondary Outcome:

  • AUCgly(0-90) for Test Zinc-IPMP, Test Zinc Non-IPMP, Positive Control, Non-SLS Negative Control and SLS Negative Control [ Time Frame: Baseline up to 90 min ]
    AUCgly(0-90) for test zinc-IPMP, test zinc non-IPMP, positive control, non-SLS negative control and SLS negative control was calculated using trapezoidal method.
  • AUCregrowth(0-90) for Test Zinc-IPMP, Test Zinc Non-IPMP, Positive Control, Non-SLS Negative Control and SLS Negative Control [ Time Frame: Baseline up to 90 min ]
    AUCregrowth(0-90) for test zinc-IPMP, test zinc non-IPMP, positive control, non-SLS negative control and SLS negative control was calculated using trapezoidal method.
  • AUClive:Dead(0-90) for Test Zinc-IPMP, Test Zinc Non-IPMP, Positive Control, Non-SLS Negative Control and SLS Negative Control [ Time Frame: Baseline up to 90 min ]
    AUClive:dead(0-90) for test zinc-IPMP, test zinc non-IPMP, positive control, non-SLS negative control and SLS negative control was calculated using trapezoidal method.


Original Secondary Outcome: Same as current
