Abstract:
The oral cavity harbors a diverse population of microorganisms,making it one of the most heavily colo-nized sites in the human body.Maintaining a balanced microecology is crucial for oral health.Ligilactobacillus salivarius as a species of Ligilactobacillus,has good oral colonization ability and potential to improve oral microecology for disease prevention and control.Currently,the application and mechanism of Ligilactobacillus salivarius in oral diseases include several aspects.First,by directly inhibiting the growth of Streptococcus mutans and downregulating the expression of its cariogenic virulence factor,gtfs,the aim is to reduce the number of adherent Streptococcus mutans on the tooth surface,thereby preventing dental caries.Second,reducing the number of keystone taxa in periodontitis,and the virulence fac-tors of Aggregatibacter actinomycetemcomitans,including CdtB and LtxA,can alleviate local stimulation in patients with periodontitis.Additionally,directly inhibiting macrophage MAPK and NF-κB pathway activation suppresses osteoclasto-genesis and reduces periodontal bone absorption.In mucosal inflammation,Ligilactobacillus salivarius competes with Candida albicans,inhibits the formation of pathogenic hyphae or germ tubes,and prevents monilial stomatitis.Ligilacto-bacillus salivarius can also reduce the amount of Staphylococcus aureus and mitigate the activation of the macrophage TLR/PI3K/Akt/mTOR and TLR/PI3K/Akt/IκB/NF-κB pathways induced by S.aureus infections,thus alleviating inflam-mation in the oral and pharyngeal regions.In vitro studies on oral tumors have revealed that Ligilactobacillus salivarius can downregulate the expression of cancer cell Akt/Cyclin D1,induce direct apoptosis of tumor cells,reduce COX-2 ex-pression,and improve the tumor immune-suppressive microenvironment.Previous studies have revealed considerable variability in Ligilactobacillus salivarius,necessitating more detailed research to clarify its clinical effects,safety,and mechanisms.Despite the emergence of novel microbiological research techniques,their application to Ligilactobacillus salivarius remains relatively limited.One crucial direction for future research is to better utilize these methods to investi-gate the effects of Ligilactobacillus salivarius on oral diseases.Considering these factors,this study provides a compre-hensive review of existing research studies on Ligilactobacillus salivarius in the fields of oral medicine and dentistry,with the aim to serve as a reference and guide for future studies.
