Introduction: for people of older age groups, ageist exposure in itself is a psychological trauma, although it is not of an existential nature. But the facts of the ageist attitude are cumulative, and its consequences are individual. An elderly person experiencing permanent implicit ageistic effects tries to avoid visiting places where this kind of injury is possible, including dental medical institutions. The purpose of the study: to analyze the influence of the perception of medical gerontological ageism on the motivation of patients of older age groups to receive dental treatment. Materials and methods. 192 people of older age groups participated in the study. At the first stage, the E. Palmore questionnaire was offered to patients to analyze the personal perception of medical gerontological ageism. Based on the responses received, groups with minimal perception of medical gerontological ageism and with maximum perception of medical gerontological ageism were formed among elderly (n=96) and senile (n=96) patients. At the second stage, a comparative assessment of the intensity of caries (components of the CPI index) and the periodontal condition (PMA index) was carried out. The results of the study. Based on the index assessment, it was proved that both among elderly and senile patients in groups with a maximum perception of medical gerontological ageism, the number of teeth removed and the periodontal condition are significantly worse than in groups with a minimum perception of medical gerontological ageism. Conclusions: in elderly and senile patients with the maximum perception of medical gerontological ageism (MaVMGE). The indices of CPI and RMA are higher than in elderly patients and patients of older age groups with minimal perception of medical gerontological ageism (MiVMGE).
