Further study details as provided by Oragenics, Inc.:

Primary Outcome Measures:
  • Enumeration of S. mutans in saliva and seven periodontal pathogens in subgingival plaque [ Time Frame: 12 weeks ]
    Quantitative RT-PCR analyses for S. mutans in saliva, and A. actinomycetemcomitans, P. intermedia, T. forsythia, F. nucleatum, C. rectus, and E. corrodens in subgingival dental plaque.

Secondary Outcome Measures:
  • Breath odor [ Time Frame: 12 weeks ]
    Halimeter used to evaluate breath odor

  • Teeth whiteness [ Time Frame: 12 weeks ]
    Teeth whiteness measured with VITA Toothguide 3D-MASTER

Estimated Enrollment: 48
Study Start Date: January 2012
Estimated Primary Completion Date: August 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Probiotic tablet Other: ProBiora3 mints
Probiotic mint tablet taken once daily for 12 weeks containing ProBiora3, a combination of three known healthy bacteria
Other Names:
  • EvoraPlus
  • EvoraPro
Placebo Comparator: Placebo tablet
Comparison tablet without the probiotic bacteria
Other: Placebo tablet
Mint tablet taken once daily for 12 weeks without the ProBiora3 combination of three known healthy bacteria
Other Name: placebo

Detailed Description:
There are over 500 types of bacteria in the mouth. Most of these bacteria do not cause disease. However, some mouth bacteria can cause tooth decay and gum disease. The purpose of a probiotic tablet for the mouth is to put known healthy bacteria in the mouth. This study will compare the effect of the probiotic tablet on the levels of harmful or disease causing bacteria in the mouth to a placebo tablet that does not contain any probiotic bacteria.
