Preventive effect of LMT18-32 on induced periodontitis.

Periodontitis is a severe gum infection leading to chronic inflammation in the gums, damage of tissues around teeth, and destruction of alveolar bones. is the major causative pathogen that induces periodontitis. Numerous probiotic bacteria are reported to produce antibacterial substances against pathogens especially oral pathogens, and these are proposed as preventive measures for periodontitis. In this study, LMT18-32 was evaluated and its antibacterial activity against and antioxidant activity in vitro were established. In addition, when LMT18-32 was administered to periodontitis induced mice, it successfully alleviated the alveolar bone loss and suppressed induced expression of proinflammatory and tissue destruction related genes in the gingival tissue. In conclusion, LMT18-32 is proposed as a potential probiotics to prevent periodontitis.
