The first presentation investigates the biological underpinnings, examining how oral bacteria moderate the link between tooth loss and cognitive performance. It reveals that a high periodontal bacterial load significantly worsens cognitive dysfunction, even with minimal tooth loss, emphasizing oral hygiene’s critical role. The second presentation provides clinical evidence, assessing how multiple oral health issues—such as tooth loss, dental plaque, and periodontal symptoms—contribute to domain-specific cognitive decline, notably impacting memory and executive function. The third presentation explores behavioral dimensions, analyzing how cognitive impairment affects dental care utilization across insurance types. It highlights reduced access among those with no insurance or Medicare-only, signaling a need for policy reform. The fourth presentation adopts a life course perspective, exploring how edentulism and social mobility jointly shape cognitive trajectories, with effects varying by age. Collectively, these studies illuminate the bidirectional relationship between oral health and cognitive function, offering actionable insights for prevention, clinical intervention, and policy enhancements to improve older adults’ quality of life.","cbCaisSXuw8Ppir9","https://ap.wps.com/l/cbCaisSXuw8Ppir9","pdf",704611,"English","# Abstract citation ID: igaf122.1222\n## Biological perspectives\n## Clinical evidence\n## Behavioral and access dimensions\n## Life-course perspective and social mobility","[{\"question\":\"How do oral bacteria affect cognitive performance in older adults?\",\"answer\":\"The symposium reports that a high periodontal bacterial load significantly worsens cognitive dysfunction even when tooth loss is minimal, indicating oral bacteria can moderate the tooth loss–cognition link.\"},{\"question\":\"Which oral health factors are discussed in the clinical evidence section?\",\"answer\":\"The clinical section evaluates multiple oral health issues, including tooth loss, dental plaque, and periodontal symptoms, and links them to domain-specific cognitive decline such as memory and executive function.\"},{\"question\":\"How does cognitive impairment influence dental care utilization?\",\"answer\":\"The behavioral presentation analyzes how cognitive impairment affects dental care utilization across insurance types, highlighting reduced access among those with no insurance or Medicare-only and pointing to policy reform needs.\"}]","ORAL HEALTH & COGNITIVE IMPAIRMENT - Biological, Clinical, and Social Perspectives - Symposium | PDF",1790639303]
