This systematic review aimed to evaluate the association between in the oral cavity as an extragastric reservoir and oral diseases in patients with or without gastritis. Following the PRISMA guidelines, a comprehensive search was conducted on the PubMed, Scopus, Cochrane Central, and Embase databases (2010-2025) using MeSH terms and keywords related to , the oral cavity, and oral diseases. Inclusion criteria included observational studies, clinical trials, and case-control studies. Data extraction and quality assessment were performed using the Newcastle-Ottawa Scale (NOS). Of the 298 records initially identified, 22 studies met the inclusion criteria. The presence of in the oral cavity (plaque, saliva) was variably associated with gastritis, periodontitis, dental caries, and halitosis. Detection rates varied widely (0-100%), influenced by methodological differences (PCR, culture, antigen tests). Some studies reported an improvement in oral health after eradication therapy, while others found no significant association. The oral cavity may serve as a reservoir for , with implications for oral and systemic health. Standardized diagnostic methods and integrated treatment approaches (combining gastric eradication and oral hygiene) are needed to clarify their role and optimize clinical outcomes. Further research is warranted to establish causal relationships and therapeutic strategies.

Background: Sjögren's syndrome (SS) is a chronic autoimmune disease delineated by excessive lymphocyte infiltration to the lacrimal or salivary glands, leading to dry eye and dry mouth. Exosomes secreted from mesenchymal stem cells (MSC) are known to have anti-inflammatory and tissue regeneration abilities. This study endeavored to demonstrate the effect of MSC-derived exosomes on the clinical parameter of dry eyes and associated pathology in SS mouse model.

Chronic inflammation and microbial dysbiosis have been implicated in the development of head and neck squamous cell carcinoma (HNSCC), particularly oral cavity squamous cell carcinoma (OSCC). Periodontitis is a common chronic inflammatory disease characterized by the progressive destruction of tooth-supporting structures. While periodontitis Has been associated with an increased risk of OSCC in epidemiological and mechanistic studies, the strength of this association is unclear.

In Canada, the incidence of human papillomavirus (HPV)-related head and neck cancer (HNC) is increasing. The role of multiple oral HPV infections in HNC etiology remains unclear, and evidence of HPV vaccination's effectiveness in reducing HNC incidence is limited. We investigated oral HPV co-infection patterns, estimated the association between multiple oral HPV infections and HNC risk, and the effect of eliminating vaccine-targeted HPV genotypes on HNC incidence.

Background: Although oral diseases and frailty can be met earlier in life, there is limited information on their association across the lifespan.
Objectives: To scope for the association of oral factors with physical frailty in Greek community-dwelling adults.
Methods: Participants were over 18 years of age with ≥ 20 natural teeth, ≥ 10 occlusal contacts, and no removable dentures.

Purpose: There is limited evidence to guide the use of enteral nutrition (EN) for children with bronchiolitis who received Humidified high flow nasal cannula (HHFNC) and often kept nil per mouth for aspiration and progression to mechanical ventilation risk.
Methods: This quality improvement project included children with bronchiolitis who were supported by HHFNC in the paediatric intensive care unit (PICU). An algorithm to increase EN use in those participants was created by stakeholders.
