Iwasaki M, et al. - Experts conducted a 5-year longitudinal study to explore the relationship between mild cognitive impairment (MCI), periodontitis, periodontal inflammation in older adults. To define severe periodontitis, they used case definitions provided by the European Workshop in Periodontology Group C and the Centers for Disease Control/American Academy of Periodontology. Findings suggested an association of severe periodontitis and periodontal inflammation with incident MCI among older community-dwelling men and women. They also noted an association of periodontal inflammation assessed by periodontal inflamed surface area with higher odds ratios for MCI.
