Why it matters for dental
A 10-year cohort study found that adults with the worst periodontal status had a 56-72% higher risk of developing dementia; dental practices that treat older adults should consider how routine periodontal therapy might fit into broader cognitive-health conversations with patients and referring physicians.
Key points
- Researchers followed 1,396 adults aged 60 years and older without dementia for 10 years and recorded 267 incident dementia cases.
- Highest-quartile mean probing pocket depth, clinical attachment level, and bleeding on probing at baseline were each linked to higher all-cause dementia risk.
- Elevated bleeding-on-probing percentage showed an association with Alzheimer’s disease risk; higher probing depth showed a non-significant trend with vascular dementia.
- Time-varying Cox models using periodontal measures at both baseline and 5 years produced similar dementia associations.
