Elderly, Cognitive Function, Mini-Mental State Examination (MMSE), Periodontal Mechanoreceptors (Pdms), Hippocampus

Abstract [English]

When a person reaches the elderly phase, the function of the body's organs decreases, which causes an increased risk of disease and death. Including dental infections such as caries and periodontal disease which are the main factors for tooth loss. Tooth loss does not only affect the impact of mastication but also affects a person's cognitive function. This condition occurs because when a person loses teeth, the function of the Periodontal Mechanoreceptors decreases, disrupting the function of the hippocampus which is important for memory in the brain. Loss of a large number of teeth tends to indicate low cognitive function, but several factors affect cognitive function, namely education level, Diabetes Mellitus, Hypertension, heart disease, depression, sleep disorders, head injury, physical activity, and a history of smoking. Mini-Mental State Examination (MMSE) is a tool to assess a person's cognitive function. This study aims to see the description of cognitive function in the elderly at the Geunaseh Sayang Nursing Home with variations in the number of tooth losses. This study was conducted with 43 research subjects with interviews and intra-oral examination methods. Based on the results of the study, it can be concluded that the elderly who only have fewer teeth show a higher decline in cognitive function compared to the elderly with more teeth in the oral cavity. This is following the theory which states that the more teeth you lose, the lower your cognitive function will be.
