Evaluation of dental care and the prevalence of tooth decay among middle-aged and elderly population of Kaunas city.

UNLABELLED The aim of the study was to evaluate the prevalence and the intensity of tooth decay among the middle-aged and elderly population of Kaunas, city, and to assess the need for prostheses as well as the possibilities for oral care. MATERIAL AND METHODS During 2006-2008, we studied 1,141 inhabitants of Kaunas city; the subjects' age was 45-72 years. Oral evaluation technique proposed by the WHO was used in the investigation. We evaluated the prevalence of tooth decay, and its intensity was evaluated using the DMF-T index. We also evaluated dental prostheses, the need for prosthetics, and asked the subjects how they took care of their oral health. RESULTS The prevalence of tooth decay among middle-aged and elderly population of Kaunas city was 99.9%. The DMF-T index was 21.01+/-0.3 in the age group of 45-54 years, 23.52+/-0.4 - in the age group of 55-64 years, and 25.63+/-0.3 - in the elderly subjects. Full removable dentures were found in 14.0% of the elderly subjects, while 1.0% of the middle-aged subjects and 1.2% of the elderly subjects required full dentures. 57.7% of the subjects aged 45-54 years, 53.1% of the subjects aged 55-64 years, and 43.4% of the elderly subjects brushed their teeth twice daily. CONCLUSIONS The intensity of tooth decay in middle-aged and elderly population of Kaunas city significantly increased with age (21.01-25.63). A relationship was found between oral hygiene status and the DMF-T index. In the middle-aged and elderly population of Kaunas city, the intensity of tooth decay was significantly lower (DMF-T 23.04%) among those who brushed their teeth twice daily than among those who brushed their teeth once daily or less frequently (DMF-T 24.01%). Reduction of the prevalence of tooth decay among middle-aged and elderly population of Kaunas city necessitates alterations in people's attitudes towards dental care, implementation of suitable hygiene habits, and creation and implementation of the dental disease prevention program for adults and the elderly, based on the strategy proposed by the World Health Organization.
