Hypothesis
Denture use is associated with better cognitive function and a slower rate of cognitive decline among Chinese older adults with tooth loss over a 10‐year period.
Conclusion
Denture use may help protect against cognitive decline in older adults with partial tooth loss.
Supporting Evidence
- Denture users had better baseline cognitive function compared to non-denture users.
- Denture use was associated with a slower annual decline in cognitive function among dentate participants.
- Results were consistent across various subgroup analyses.
Takeaway
Wearing dentures can help older people with missing teeth think better and slow down how quickly they forget things.
Methodology
Data from the Chinese Longitudinal Healthy Longevity Survey (2008–2018) was analyzed using linear mixed‐effect models to assess cognitive function and denture use.
Potential Biases
Potential recall bias due to reliance on interview questionnaires for dental status and health behaviors.
Limitations
The study lacked detailed dental examination data and relied on self-reported measures, which may introduce bias.
Participant Demographics
Mean age of participants was 86 years, with 43.4% men and 35.2% edentulous.
