Thanks for visiting TheraBreath.com to learn more about the recent study conducted by PRINCETON CONSUMER RESEARCH using the test article, TheraBreath Toothpaste.

A randomized, double blind study in 64 subjects to evaluate the efficacy of one test article to control the breath odour 13 hours after a single use compared to an untreated control group and a positive control group using hedonic assessments

The study concluded: "that for the test articles the claims of 'breath freshening' and 'freshens breath for over 12 hours' are valid."


Summary of Results

LOCATION AND DATES OF THE STUDY:
The study was performed at Princeton Consumer Research, Princeton Forrestal Center, 307 College Road East, Princeton, NJ, 08540, USA, between 13th October 2014 and 24th October 2014.

SUBJECTS:
64 subjects were recruited into the study and 49 subjects completed the study. Eight subjects were removed from the study for non-compliance or withdrew due to reasons unrelated to the study.

ADVERSE EVENTS, ADVERSE REACTIONS AND SUBJECTS NOT COMPLETING THE STUDY:
No adverse events or reactions were reported. All subjects completed the study.

ASSESSMENTS:
There was no statistically significant difference for the pre-treatment assessments between the test groups for any of the judges or between judges (p>0.05) so the study can be considered valid. Both the Test Article and Positive Control showed a highly statistically significant difference to the untreated baseline sites (p<0.005) in all assessments. All judges were statistically similar at all-time points and sites (p>0.05) and so assessments can be considered as accurate.
