Outcome Measures

Primary Outcomes (4)

• Change in Microbial colonization from baseline (Day 0) to 1 hour

  Study will determine the change in the microbial colonization efficacy of three different doses of S. salivarius M18 in a toothpaste format. Study will determine the change in microbial colonization efficacy of Streptococcus salivarius M18 in a toothpaste format. The saliva Statistical analysis (e.g. ANOVA) will be carried out to compare the participants data from baseline to one hour after later across three different formulations with the level of significance of p≤0.05.Overall colonization based on percentage of population colonized for different interventions will also be analyzed average and standard deviation functions using appropriate statistical analysis software (e.g. Microsoft Excel, GraphPad Prism).

  1 hour post intervention

• Change in Microbial colonization from baseline (Day 0) to 8 hours

  Study will determine the change in the microbial colonization efficacy of three different doses of S. salivarius M18 in a toothpaste format. Study will determine the change in microbial colonization efficacy of Streptococcus salivarius M18 in a toothpaste format. The saliva Statistical analysis (e.g. ANOVA) will be carried out to compare the participants data from baseline to one hour after later across three different formulations with the level of significance of p≤0.05.Overall colonization based on percentage of population colonized for different interventions will also be analyzed average and standard deviation functions using appropriate statistical analysis software (e.g. Microsoft Excel, GraphPad Prism).

  8 hours post intervention

• Change in Microbial colonization from baseline (Day 0) to 24 hours

  Study will determine the change in the microbial colonization efficacy of three different doses of S. salivarius M18 in a toothpaste format. Study will determine the change in microbial colonization efficacy of Streptococcus salivarius M18 in a toothpaste format. The saliva Statistical analysis (e.g. ANOVA) will be carried out to compare the participants data from baseline to one hour after later across three different formulations with the level of significance of p≤0.05.Overall colonization based on percentage of population colonized for different interventions will also be analyzed average and standard deviation functions using appropriate statistical analysis software (e.g. Microsoft Excel, GraphPad Prism).

  24 hours post intervention

• Change in Microbial colonization from baseline (Day 0) to 24 hours post last dose

  Study will determine the change in the microbial colonization efficacy of three different doses of S. salivarius M18 in a toothpaste format. Study will determine the change in microbial colonization efficacy of Streptococcus salivarius M18 in a toothpaste format. The saliva Statistical analysis (e.g. ANOVA) will be carried out to compare the participants data from baseline to one hour after later across three different formulations with the level of significance of p≤0.05.Overall colonization based on percentage of population colonized for different interventions will also be analyzed average and standard deviation functions using appropriate statistical analysis software (e.g. Microsoft Excel, GraphPad Prism).

  24 hours after last dose following 7 days of daily brushing with probiotic toothpaste.
