To evaluate the colonisation efficacy (i.e. ability of the probiotic bacteria to remain in your mouth) of a fast melt powder that quickly dissolves in the mouth. The fast melt powder will contain a Streptococcus salivarius probiotic and the study is to be done in healthy adults.
This is a double-blind, randomized controlled study with no cross over to evaluate the colonization efficacy of fast melt powders containing a commercially available probiotic bacterium Streptococcus salivarius K12.
Participants will be randomly assigned to one of the 2 groups consuming Fast Melt powder containing two different doses of Streptococcus salivarius K12 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.

| Probiotic Streptococcus salivarius K12 Fast Melt Powder 1 Billion colony forming units /g) | Dietary Supplement | Probiotic Streptococcus salivarius K12 products are commercially available in traditional formats such as chewable tablet (lozenge) for local delivery in the oral cavity to provide oral health benefits. In this study, a Fast Melt Powder formulation will be evaluated for its potential of delivering probiotic Streptococcus salivarius K12 to the oral cavity. |
| Measure | Description | Time Frame |
|---|---|---|
| Change in microbial colonization from baseline (Day 0) to 1 hour | Study will determine the change in microbial colonization efficacy of two different doses of Streptococcus salivarius K12 in a fast melt powder format. The saliva Statistical analysis (e.g. Students t-test) 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). | 1 hours post intervention |
| Change in microbial colonization from baseline (Day 0) to 8 hours | Study will determine the change in microbial colonization efficacy of two different doses of Streptococcus salivarius K12 in a fast melt powder format. The saliva Statistical analysis (e.g. Students t-test) will be carried out to compare the participants data from baseline to 8 hours 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). | 8 hours post intervention |
| Change in microbial colonization from baseline (Day 0) to 24 hours | Study will determine the change in microbial colonization efficacy of two different doses of Streptococcus salivarius K12 in a fast melt powder format. The saliva Statistical analysis (e.g. Students t-test) will be carried out to compare the participants data from baseline to 24 hours 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). | 24 hours post intervention |
| Change in microbial colonization from baseline (Day 0) to 48 hours post last dose |
