Secondary adentia is still the most common condition among the middle-aged and elderly population of the Russian Federation and the Belgorod agglomeration. Adentia acts as a factor that negatively affects the level of general somatic health, which is especially pronounced among women. The aim of this cohort two-stage study conducted among elderly women was to consistently determine the dynamics of the dental status of the formed sample in 2017 and in 2022. At the first stage, 384 women aged 61.4 ±2.2 years were examined, at the second stage, the same sample was examined, reduced to 331 people aged 64.8 ± 1.9 years. The socio-economic status of the sample differs in the following characteristics: women aged 60-65 years, who are in stable family relationships, with an average per capita income of ≈ 50% higher than the subsistence minimum established for pensioners of the Belgorod region, who have received an education above the full average. The dynamics of the need for sanitation of the oral cavity is largely determined by the frequency of hygienic procedures. The need for periodontal treatment was assessed by calculating the need index for the treatment of periodontal diseases CPITN (Community Periodontal Index of Treatment Needs,). In women who do not regularly perform hygienic procedures, the CPITN index has lower values than in women who perform hygienic procedures properly. The revealed dynamics is due to the number of teeth removed due to periodontitis. The severity and intensity of caries, considered as the need for caries treatment, was determined by calculating the CPI index, defined as the sum of carious (K), filled (N) and removed (Y) teeth. The dynamics of the CPI index confirms the observed dynamics due to a significant increase in the «removed teeth» component.
