Actuality: Adentia is an age–related change in the oral cavity, accompanied by loss of teeth. Age-related physiological changes in teeth should be carefully distinguished from pathological changes, especially when they cause pain or have a negative impact on the quality of life of elderly people associated with oral health. All this leads to eating disorders. Poor oral health was independently associated with the development of the frailty. However, due to the small amount of data on the effect of age-related oral cavity disorders on geriatric status, further tests are necessary, which actualized the study. Objective: To study the effect of the degree of adentia on geriatric status. Materials and methods: The basis of the leading criterion for the diagnosis of age-related oral cavity syndrome was the study of the degree of adentia according to the classification of E. Kennedy. A total of 284 people aged 60 to 74 years participated in the study. In the course of the study, scales were used to determine geriatric syndromes by complex geriatric assessment, as well as by the "Senile asthenia Phenotype" scale described by L. Fried et al. (2001), as well as cognitive impairment and dementia on the MMSE scale. Results: When assessing the geriatric status, we revealed data on a high expert assessment of the influence of the age-related oral cavity on the development of such geriatric syndromes as sarcopenia (χ2 = 11.34, p= 0.0032), pre-segment cognitive impairment (χ2 = 10.11, p= 0.0140) and moderate-severe cognitive impairment (χ2 = 9.37, p= 0.0118). Assessing the prevalence of deficiency syndromes, we found that the absence of 11-36 teeth significantly significantly worsens the geriatric status compared to the absence of 1-10 teeth or the presence of teeth. In the course of our study, the phenotype of the frailty also had a negative trend with a significant degree of adentia. In the absence of 11-36 teeth, there was an aggravation of the frailty to 3.9 points compared with 0.2 points in patients who had all teeth. It turned out to be an interesting fact that starting from the level of loss of 11 teeth and more progressively increased cognitive impairment, in particular, the aggravation of dementia was noted. Conclusions: Severe forms of adentia as the main component of the age-related oral cavity syndrome leads to various kinds of nutritional imbalances, primarily nutritional deficits, which leads to the risk of developing a syndrome of malnutrition or to the manifestation of malnutrition itself, which, accordingly, causes or exacerbates the existing dina/sarcopenia, cognitive deficits and increases the risk of falls syndrome.
