However, studies examining the relationship between occlusal support and peripheral biomarkers such as salivary amyloid-\u03b242 (A\u03b2\n                    <jats:sub>42<\/jats:sub>\n                    ) remain limited.\n                    <jats:bold>Objective:<\/jats:bold>\n                    This study examined the association between occlusal support and cognitive decline by analyzing salivary A\u03b2\n                    <jats:sub>42<\/jats:sub>\n                    levels in older adults.\n                    <jats:bold>Methods:<\/jats:bold>\n                    A cross-sectional study was conducted among 62 participants categorized by occlusal support using the Eichner Index. Meanwhile, cognitive function and daily living abilities were assessed using the Mini-Mental State Examination (MMSE) and Lawton Instrumental Activities of Daily Living Scale (IADL).
