The strongest epidemiological evidence was observed for depressive disorders and anxiety- and stress-related conditions. However, the predominance of cross-sectional studies, together with substantial methodological heterogeneity, limits conclusions regarding temporality and causality. From a mechanistic perspective, the available evidence regarding the association between periodontitis and neuropsychiatric disorders predominantly supports as mechanisms (1) microbial pathways (microbial translocation and functional dysregulation of the oral microbiome), (2) inflammatory and immune pathways (systemic (meta)inflammation and trafficking of immune players systemic), and (3) shared underlying vulnerabilities (behavioral factors, medication-related effects, lifestyle and systemic health factors, and genetic mechanisms). Periodontitis may promote a persistent low-grade systemic inflammatory state through the release of bacterial products and inflammatory mediators into the circulation, thereby influencing immune, neuroendocrine, and vascular pathways relevant to neuropsychiatric vulnerability. Moreover, the hematogenous dissemination or swallowing of periodontal bacteria and their virulence factors may contribute to microbial remodeling at distant sites, including the gut, supporting the concept of an oral-gut-brain axis.

Psoriasis and other inflammatory skin disorders, including atopic dermatitis and alopecia, are immune-mediated conditions driven by complex interactions between genetic susceptibility, environmental triggers, microbial factors, and cytokine network activation. Mounting epidemiological and experimental evidence suggests a consistent association between periodontitis and psoriasis, with emerging links to other skin disorders. This narrative review critically appraised the current available evidence regarding the epidemiological association between periodontitis and inflammatory skin disorders, explored the shared pathogenic mechanisms underpinning a potential oral-skin axis, and evaluated the impact of periodontal therapy on dermatological outcomes. Epidemiological and meta-analytical data suggest a positive association between periodontitis and psoriasis across diverse populations, although direct causality remains unclear. Mechanistically, overlapping pathways include systemic dissemination of pro-inflammatory cytokines (e.g., IL-6, TNF-α, IL-17), Th17-driven immune responses, neutrophil priming and NETosis, microbial translocation, and shared lifestyle-related determinants within the multimorbidity framework. Preclinical and clinical randomized controlled trials suggest that non-surgical periodontal therapy may reduce psoriasis severity and extent over the short term (8-10 weeks), potentially acting as a relevant adjunct to dermatologic medications. While heterogeneity and residual confounding limit definitive conclusions, the convergence of epidemiological, mechanistic, and interventional evidence supports the plausibility of a bidirectional interaction between periodontal and skin inflammation and the potential existence of an oral-skin axis.

Secreted by major and minor salivary glands and enriched by gingival crevicular fluid, epithelial turnover, immune mediators, microbial products, and plasma-derived constituents, saliva reflects a biologically integrated interface between local oral environments and systemic physiology. This dual origin enables detection of disease-associated signals across multiple molecular layers, including extracellular RNA, cell-free DNA, genomic and epigenetic material, proteins, metabolites, microbial signatures, and hormones. Advances in high-throughput sequencing, mass spectrometry, and ultrasensitive immunoassays have revealed that salivary analytes can capture dynamic pathological processes ranging from periodontal inflammation and dental caries to oral and head and neck cancers, as well as systemic conditions such as non-oral cancers and autoimmune, cardiometabolic, infectious, endocrine, and neurodegenerative diseases. In particular, extracellular vesicle-encapsulated RNA, cfDNA fragmentomics, and methylation patterns have expanded the diagnostic reach of saliva beyond conventional protein-based biomarkers, while integrated multi-omics approaches increasingly improve diagnostic performance. Despite this progress, clinical translation remains constrained by biological complexity, including variable glandular contributions, oral microbiome interactions, and pre-analytical variability in collection and processing. Emerging point-of-care technologies, microfluidic platforms, and artificial intelligence-driven multi-omic integration are beginning to address these limitations, enabling higher analytical sensitivity and improved disease stratification. Regulatory pathways, including in vitro diagnostic frameworks and laboratory-developed test structures, are progressively accommodating salivary assays, as demonstrated during the COVID-19 pandemic. However, widespread clinical adoption will require rigorous standardization, large-scale validation, and demonstration of clinical utility.

Increasing evidence supports an oral-hepatic axis through which periodontal dysbiosis and chronic oral inflammation may influence hepatic homeostasis and disease progression. Epidemiologic studies have linked periodontitis with metabolic dysfunction-associated steatotic liver disease (MASLD), nonalcoholic fatty liver disease (NAFLD), viral hepatitis, cirrhosis, and hepatocellular carcinoma. Although many associations persist after adjustment for shared risk factors, including obesity, diabetes, smoking, nutritional status, and socioeconomic factors, the independent contribution of periodontitis to liver disease remains unclear. Experimental and translational studies indicate that periodontal pathogens and their virulence factors promote systemic inflammation, endotoxemia, microbial translocation, immune dysregulation, and alterations in gut microbial ecology. Nutritional factors may further influence these interactions through their effects on host immunity, inflammation, and microbial communities. Together, these mechanisms converge along the oral-gut-liver axis to activate hepatic inflammatory, oxidative stress and profibrotic pathways that contribute to steatosis, immune activation, and fibrogenesis. Emerging evidence suggests that trained immunity, driven by metabolic and epigenetic reprogramming, may represent an additional mechanism linking periodontitis and liver disease warranting future studies. Preliminary studies indicate that periodontal therapy may reduce systemic inflammatory burden and improve hepatic biomarkers; however, evidence for an effect on liver disease progression or clinical outcomes remains limited. Similarly, hepatic dysfunction may exacerbate immune dysregulation and periodontal breakdown, reinforcing an inflammatory loop. However, overall causal relationships remain to be established. This review summarizes current epidemiological, clinical, and mechanistic evidence linking periodontitis and chronic liver diseases, highlighting the oral-gut-liver axis, shared immunometabolic and nutritional pathways. Understanding these interactions shows the significance of integrated dental-medical care and opens new avenues for prevention and adjunctive therapy to sustain oral and hepatic health.</p>","PeriodicalId":16715,"journal":{"name":"Journal of periodontal research","volume":" ","pages":""},"PeriodicalIF":5.4,"publicationDate":"2026-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148794742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review critically evaluates the reported role of Fusobacterium nucleatum in cancer, highlighting new findings that suggest a more nuanced cross-talk with the disease. We contextualise current evidence on the interactions with the wider tumour micro-environment, including the roles of polymicrobial communities, microbial metabolites and taxonomic heterogeneity. Collectively, the evidence suggests that Fusobacterium nucleatum should not be regarded as universally pathogenic or oncogenic. Rather, its behaviour is likely context-dependent and shaped by its surrounding microenvironment. Notably, opposing pro- and anti-tumoural mechanisms can coexist within the same cancer type. For example, in colorectal cancer, F. nucleatum is predominantly associated with poorer outcomes by promoting immune evasion (e.g., suppression of cytotoxic T cell responses) and oncogenic signalling (e.g., via the E-cadherin/β-catenin pathway), yet it also displays oncosuppressive activity through promotion of neutrophil-mediated anti-tumoural cytotoxicity and butyrate-driven cytotoxic T cell activation and potentiation of immunotherapy. In head and neck cancer, by contrast, F. nucleatum detection is associated with improved survival across independent cohorts, potentially reflecting a different balance of these same competing mechanisms. We suggest implications for its proposed use as a biomarker and as a target in cancer therapy. Lingering questions are also laid out to help investigators shape future research to better capture the complexity of the TME and elucidate the overall impact of Fusobacterium nucleatum in cancer.</p>","PeriodicalId":16715,"journal":{"name":"Journal of periodontal research","volume":" ","pages":""},"PeriodicalIF":5.4,"publicationDate":"2026-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148759720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
