The Potential Teeth Bleaching and Halitosis Prevention Effects of Pediococcus Inopinatus THK-30, a Kimchi-Derived Lactic Acid Bacterium: An In Vitro Study

The study investigated the potential of Pediococcus inopinatus THK-30, a lactic acid bacterium derived from kimchi, for teeth bleaching and halitosis prevention. The bacterium showed significant antibacterial activity against oral pathogens related to halitosis, including Streptococcus mutans, Porphyromonas gingivalis, and Fusobacterium nucleatum. It also demonstrated teeth bleaching effects and inhibited biofilm formation, both independently and in combination with 8% sodium hexametaphosphate (SHMP). The study suggests that Pediococcus inopinatus THK-30 could be a potential natural agent for oral care, specifically for teeth bleaching and halitosis prevention. However, further research is needed to confirm these findings.
