BACKGROUND: Periodontitis and inflammatory bowel disease (IBD) are chronic inflammatory conditions of the oral and gastrointestinal tracts that exhibit bidirectional microbial and immunological crosstalk.
OBJECTIVE: Aimed at elucidating the bidirectional crosstalk between periodontitis and IBD at both microbiological and immunological levels and evaluate related therapeutic interventions, this review comprehensively summarizes recent evidence on their interaction via the oral-gut-bone axis, focusing on microbial ecology, host responses, and innovative therapies.
DESIGN: Distinct yet overlapping dysbiotic signatures are observed in both diseases, with periodontal pathogens such as Porphyromonas gingivalis and Fusobacterium nucleatum capable of translocating to the gut and perturbing intestinal homeostasis, while gut inflammation reciprocally reshapes the oral microbiome. Mechanistic links include a spectrum of convergent pathways: (i) microbial metabolites-short-chain fatty acids, choline metabolites, indole derivatives, polyamines, and bile acids-that modulate barrier integrity and immune responses; (ii) shared immune cells and inflammatory mediators driving mucosal damage at both sites; (iii) bacterial extracellular vesicles (BEVs) and lysine lactylation (Kla)-mediated signaling; and (iv) oxidative stress, iron metabolism dysregulation, and ferroptosis contributing to tissue destruction.
RESULTS: Therapeutic strategies targeting this axis encompass bidirectional interventions: periodontal and IBD treatments that mutually influence oral and gut health, natural anti-inflammatory and antimicrobial compounds, probiotics and prebiotics, oral and fecal microbiota transplantation, and emerging bacteriophage therapy. Critically, the clinical translation of collaborative dentistry-gastroenterology management is highlighted as a promising avenue for integrated care.
CONCLUSIONS: By integrating findings across microbial ecology, host response, and therapeutic innovation, this review provides a comprehensive framework for understanding and targeting the periodontitis-IBD axis.
