Why it matters for dental
Dentists in urban or high-traffic areas may face higher Lewy body and Parkinson’s-related dementia risk from chronic PM2.5 and NO2 exposure, affecting long-term workforce planning and clinic location decisions for owners and DSOs.
Key points
- Danish nationwide registry investigators tracked 2001–2021 data from more than 3,000 Lewy body dementia cases and nearly 4,000 Parkinson’s-related dementia cases against nearly 70,000 matched controls.
- Exposure to PM2.5 and nitrogen dioxide both showed correlation with later Lewy body dementia and Parkinson’s disease-related dementia after statistical adjustment.
- Practice owners in dense metropolitan areas may need to weigh air-quality data when evaluating staff retention and clinic longevity.
- No dental-specific exposure limits or regulatory guidance are stated in the study.
