A recent clinical trial studied the effects of a probiotic bacterium, Weissella cibaria CMU, on halitosis (bad breath) in adults. The study found that tablets containing W. cibaria CMU significantly reduced bad breath and improved psychological well-being in participants.

It has been completed and published by Department of Periodontology, School of Dentistry and Dental Research Institute, Seoul National University and Seoul National University Dental Hospital, Seoul, Republic of Korea. The study included 100 adults aged 20-70 years who suffered from halitosis. Participants were randomly assigned to either the test group or the control group. The test group received a daily W. cibaria CMU-containing tablet for 8 weeks, while the control group received a placebo tablet.

The researchers measured the levels of volatile sulfur compounds (VSCs), which are responsible for bad breath, as well as bad breath improvement scores and oral colonization of W. cibaria. Additionally, they assessed participants' psychological well-being by evaluating depression, self-esteem, oral health-related quality of life, and subjective oral health status.

The results showed that the probiotics group experienced a significant reduction in total VSC levels and bad breath improvement scores compared to the placebo group. The levels of W. cibaria CMU were also higher in the probiotics group, indicating better oral colonization.

Moreover, the probiotics group showed significant improvements in depression, oral health-related quality of life, and subjective oral health status from the beginning to the end of the study. No safety issues were observed in either group.

In conclusion, the use of W. cibaria CMU-containing tablets helped to reduce bad breath and improve psychological well-being in patients with halitosis. This study supports the potential benefits of using probiotics for oral health and overall well-being.
