Halitosis is referred to as an unpleasant odor coming from the mouth. Recently, probiotics have been studied as an alternative prevention for halitosis. The aim of this study was to evaluate the effects of probiotic bacterium Weissella cibaria Chonnam Medical University (CMU)-containing tablets (1?×?108 colony forming units [CFU]/g) on oral malodor. The randomized, double-blind, placebo-controlled trial was conducted in 92 healthy adults (20?39 years of age) with bad breath. All subjects were randomly assigned to a test (probiotic, n?=?49) or control (placebo, n?=?43) group after dental scaling and root planing. The tablets were taken once daily for 8 weeks. Measurements included an organoleptic test (OLT), volatile sulfur compounds (VSC), bad breath improvement (BBI) scores, and the oral colonization of W. cibaria CMU. This study also assessed safety variables of adverse reactions, vital signs, and the findings of hematology and blood chemistry. Most of the variables were measured at baseline, 4, and 8 weeks. Safety-related variables were measured at baseline and 8 weeks. At week 4, a significant decrease in OLT and VSC results was observed in the test group while BBI scores were significantly reduced at week 8 (P?
