Abstract Aim To determine whether having periodontitis is associated with cognitive decline among older adults. Material and Methods A prospective population study of older adults, Swedish National Study on Ageing and Care, ( SNAC ) provided repeated registrations of cognitive functions. Cognitive decline was defined as ≥3‐points deterioration from a predetermined level at baseline, using the Mini‐Mental State Examination ( MMSE ). Between 2001 and 2003, 715 individuals had a medical as well as a clinical and radiographic dental examination. The individuals were re‐examined after 6 years. Periodontitis was defined as ≥4 mm bone loss at ≥30% of tooth sites. Social variables were captured from questionnaires. Results The multivariate logistic regression analysis demonstrated a statistically significant association between prevalence of periodontitis and cognitive decline after adjustments of confounding factors of importance. Conclusions A history of periodontitis may be of importance for cognitive functions among older adults.
