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.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Active Comparator: Active Comparator: Streptococcus salivarius M18 toothpaste dose 1 Streptococcus salivarius M18 toothpaste containing 1 million cfu/g |
Other: Streptococcus salivarius M18 toothpaste (1 million cfu)
Probiotics Streptococcus salivarius M18 toothpaste 1 million cfu/g
In this study, a toothpaste formulation containing S. salivarius M18 will be evaluated for its potential for delivering the probiotic to the oral cavity.

| Active Comparator: Active Comparator: Streptococcus salivarius M18 toothpaste dose 2 Streptococcus salivarius M18 toothpaste containing 10 million cfu/g |
Other: Streptococcus salivarius M18 toothpaste (10 million cfu)
Probiotics Streptococcus salivarius M18 toothpaste 10 million cfu/g
In this study, a toothpaste formulation containing S. salivarius M18 will be evaluated for its potential for delivering the probiotic to the oral cavity.

Outcome Measures
Primary Outcome Measures
- Change in Microbial colonization from baseline (Day 0) to 1 hour [1 hour post intervention]
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 [8 hours post intervention]
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 [24 hours post intervention]
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).
- Change in Microbial colonization from baseline (Day 0) to 8 hours post last dose [8 hours after last dose following 7 days of daily brushing with probiotic toothpaste.]
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).
