Reporting Groups
  Description
Placebo 1st, Active Comparator 2nd and Experimental 3rd Participants brushed their teeth with the placebo control (fluoride toothpaste only)during the first intervention then brushed with active comparator(fluoride/triclosan/copolymer toothpaste) during the second intervention and experimental product (stannous fluoride toothpaste) during as the last intervention.
Active Comparator 1st, Experimental 2nd, Placebo 3rd Participants brushed their teeth with the Active Comparator (fluoride/triclosan/copolymer toothpaste)during the first intervention, then brushed with experimental product (stannous fluoride toothpaste) during the second intervention, and brushed with the placebo control (fluoride toothpaste only)as the last intervention.

Certain Agreements:  
Principal Investigators are NOT employed by the organization sponsoring the study.
There IS an agreement between Principal Investigators and the Sponsor (or its agents) that restricts the PI's rights to discuss or publish trial results after the trial is completed.
The agreement is:
unchecked The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release and can embargo communications regarding trial results for a period that is more than 60 days but less than or equal to 180 days. The sponsor cannot require changes to the communication and cannot extend the embargo.
unchecked Other disclosure agreement that restricts the right of the PI to discuss or publish trial results after the trial is completed.


Limitations and Caveats
Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
