  • From Mouth to Mind: Unraveling the Oral Microbiome's Role in Orofacial Pain and Neurodegeneration.

    Sanjana Moses, Tushar Phulambrikar, Tanvi Dosi 他 · Journal of clinical practice and research · 2026

    The human oral cavity hosts a diverse and dynamic microbiome comprising more than 700 microbial species, which plays a crucial role in maintaining oral and systemic health. Oral dysbiosis, defined as disruption of this microbial balance, has been increasingly implicated not only in periodontal disease but also in the pathogenesis of orofacial pain and neurodegenerative diseases. Key pathogens, suc…

  • Eubiosis and dysbiosis in periodontitis-related systemic diseases.

    Rajesh Kanna Gopal, Naji Naseef Pathoor, Pitchaipillai Sankar Ganesh 他 · Journal of periodontology · 2026

    This narrative review examines the eubiosis-dysbiosis spectrum in periodontitis and its systemic implications. Evidence is drawn from the literature through 2026; as a narrative review, some selection bias cannot be excluded. Periodontitis, affecting 10%-15% of adults globally, drives systemic health disorders through microbial dysbiosis. This narrative review examines microbial ecological shifts …

  • Salivary metabolomics for early detection of vascular contributions to cognitive impairment and dementia: Exploring microbiome dysbiosis and sex differences.

    Ali Yilmaz, Nadia Ashrafi, Zoe Guerra 他 · Journal of Alzheimer's disease : JAD · 2026

    BackgroundVascular factors contribute to dementia in approximately 20 million individuals, notably in vascular contributions to cognitive impairment and dementia (VCI). However, the lack of specific molecular biomarkers to differentiate VCI from normal aging and Alzheimer's disease (AD) impedes early diagnosis and treatment.ObjectiveTo date the use of saliva for VCI diagnosis has not been previous…

  • Salivary microbiome dysbiosis in patients with Alzheimer's disease.

    Asma Hamdi, Panagiota Stathopoulou, Alya Gharbi 他 · Journal of Alzheimer's disease : JAD · 2026

    BackgroundInvestigating human oral microbiota is now of great interest, being clinically significant for general and oral health. Many research studies have started to focus on the link between oral microbial dysbiosis and Alzheimer's disease. However, little is known about North African populations.ObjectiveWe aimed to distinguish the dissimilarity in the structure of microbial oral flora between…

  • Differential Patterns of Gut and Oral Microbiomes in Hispanic Individuals with Cognitive Impairment.

    Yannick N Wadop, Erin L Vasquez, Julia J Mathews 他 · Microorganisms · 2025

    Alterations in both oral and gut microbiomes have been associated with Alzheimer's disease and related dementia (ADRD). While extensive research has focused on the role of gut dysbiosis in ADRD, the contribution of the oral microbiome remains relatively understudied. This study aims to evaluate distinct patterns and potential synergistic effects of oral and gut microbiomes in a cohort of predomina…

  • Association of salivary lactoferrin, Porphyromoras gingivalis and stress hormone levels in patients with periodontitis: a pilot study.

    Desireé Antequera, Elena Buetas, Sandra García-Esteban 他 · Frontiers in immunology · 2025

    Periodontitis is a prevalent inflammatory disease characterized by a dysbiotic oral microbiome, particularly involving Porphyromonas gingivalis (P. gingivalis) as a key periodontal pathogen. This disorder has also systemic implications, including links to neurodegenerative diseases such as Alzheimer's disease (AD). Lactoferrin, an iron-binding glycoprotein involved in innate immunity, is found in …

  • Autism and the Oral Microbiome: A Systematic Review of Host-microbial Interactions and Diversity.

    Kausar Sadia Fakhruddin, Iman Kamal, Tatia Maglaperidze 他 · International dental journal · 2025

    Emerging evidence suggests a link between the oral microbiome and autism spectrum disorder (ASD), a neurodevelopmental condition characterised by social and behavioural impairments. The vast microbial reservoirs in the gut complement those of the oral cavity, suggesting a potential oral-gut-brain axis that may influence ASD and perhaps other neurological diseases, such as Parkinson's syndrome and …

  • Human oral microbiome and its influence on mental health and brain disorders.

    Alejandro Borrego-Ruiz, Juan J Borrego · AIMS microbiology · 2025

    The human oral microbiome can affect brain functions directly through the trigeminal nerve and olfactory system and indirectly via the oral-gut-brain axis. However, the potential link between the oral microbiome and mental health remains an area that requires further investigation. Taking into consideration that gut microbiota dysbiosis plays a role in the onset and progression of several mental d…

  • Age-related oral microbiota dysbiosis and systemic diseases.

    Ling Deng, Guangzhao Guan, Richard D Cannon 他 · Microbial pathogenesis · 2025

    The oral microbiota is an essential microbial community within the human body, playing a vital role in maintaining health. In older adults, age-related changes in the oral microbiota are linked to both systemic and oral health impairments. The use of various medications for systemic diseases in the elderly can also contribute to the development of oral diseases. Oral microbiota dysbiosis refers to…

  • The Oral-Gut Microbiome-Brain Axis in Cognition.

    Noorul Ain Adil, Christabel Omo-Erigbe, Hariom Yadav 他 · Microorganisms · 2025

    Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by cognitive decline and neuronal loss, affecting millions worldwide. Emerging evidence highlights the oral microbiome-a complex ecosystem of bacteria, fungi, viruses, and protozoa as a significant factor in cognitive health. Dysbiosis of the oral microbiome contributes to systemic inflammation, disrupts the blood-b…
