Denture use and a slower rate of cognitive decline among older adults with partial tooth loss in China: A 10-year prospective cohort study

Denture use may help protect against cognitive decline in older adults with partial tooth loss. This study highlights the potential importance of prosthodontic rehabilitation in preserving cognitive health.

Periodontitis associated with brain function impairment in middle-aged and elderly individuals with normal cognition

Our results confirmed that periodontitis was associated with both intra- and internetwork functional connectivity (FC) changes even in normal cognition (NC). The present study indicates that periodontitis might be a potential risk factor for brain damage and provides a theoretical clue and a new treatment target for the early prevention of Alzheimer disease.

Poor Oral Health May Contribute to the Risk of Dementia

  • Poor Oral Health Raises the Risk of Being Diagnosed with Alzheimer’s Disease & Related Dementias (ADRD)
  • ADRD Negatively Affects Oral Health and Requires Additional Care
  • Questions Remain about the Relationship Between ADRD and Oral Health
  • Research Can Help Fill in the Knowledge Gaps

Don’t forget to floss and floss so you don’t forget. Emerging evidence linking periodontal disease and dementias (CE course and peer-reviewed article)

Patients with periodontal disease are significantly more likely to develop Alzheimer’s disease than those who are periodontally healthy. This interaction is thought to be mediated by inflammation, the periodontal microbiome, and the immune reactions to those pathogens that are associated with the oral biofilm.

Diabetes, Edentulism, and Cognitive Decline: A 12-Year Prospective Analysis

Our study finds the co-occurrence of Diabetes mellitus (DM) and edentulism led to a worse cognitive function and a faster cognitive decline in older adults aged 65 to 74.

Periodontal health, cognitive decline, and dementia: A systematic review and meta-analysis of longitudinal studies

Poor periodontal health and tooth loss appear to increase the risk of both cognitive decline and dementia. However, the available evidence is limited to draw firm conclusions.

Association of periodontitis and oral microbiomes with Alzheimer’s disease: A narrative systematic review

This review suggests that periodontal infection is associated with Alzheimer’s Disease. The contributing microbiome remains unconfirmed, possibly because of different microbiome sampling sites or methods.

The Periodontal Pathogen Fusobacterium nucleatum Exacerbates Alzheimer’s Pathogenesis via Specific Pathways

The findings provide a theoretical basis for the study of the relationship between F. nucleatum and AD and lay a preliminary foundation for further exploring the mechanism of F. nucleatum impact on the onset and development of Alzheimer’s Disease

Dose-Response Meta-Analysis on Tooth Loss With the Risk of Cognitive Impairment and Dementia

Moderate-quality evidence suggested tooth loss was independently associated with cognitive impairment and dementia; risk of diminished cognitive function increased with incremental numbers of teeth lost. Further, timely prosthodontic treatment with dentures may reduce the progression of cognitive decline related to tooth loss.

Obstructive sleep apnea treatment and dementia risk in older adults

PAP treatment and adherence are independently associated with lower odds of incident AD diagnoses in older adults. Results suggest that treatment of OSA may reduce the risk of subsequent dementia.

Association between number of teeth and Alzheimer’s disease using the National Database of Health Insurance Claims and Specific Health Checkups of Japan

The results of the present study using Japanese dental claims data showed that older people visiting dental offices with fewer teeth present and a greater number of missing teeth are more likely to have Alzheimer’s disease.

Periodontal dysbiosis associates with reduced CSF Aβ42 in cognitively normal elderly

To our knowledge, this is the first report of an association between subgingival periodontal bacteria and CSF biomarkers of AD pathology in cognitively normal elderly people. We found that subgingival periodontal dysbiosis characterized by increases in periodontal‐associated bacteria and decreases in health‐related bacteria associated with reduced CSF Aβ42 but not with CSF P‐tau.
