Outcomes

Primary Outcome Measures

Change in Microbial colonization from baseline (Day 0) to 1 hour
Study will determine the change in the microbial colonization efficacy of two 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).
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).
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 two 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).

5. Study Description

Brief Summary
The aim of this study is to evaluate the colonization efficacy of probiotic toothpastes in healthy adults
Detailed Description
This is a double blind randomized controlled study with no cross over to evaluate the colonization efficacy of toothpaste containing a commercially available probiotic bacterium Streptococcus salivarius M18. Participants will be randomly assigned to one of 2 groups for brushing teeth with a probiotic toothpaste containing two different doses of Streptococcus salivarius M18 over a seven day period. Saliva samples will be collected at predetermined time points pre and post intervention. Colonization efficacy will be determined by enumerating the probiotic in the saliva samples using standard microbiological techniques.
