 Abstract
Korean society is experiencing rapid growth due to industrialization and urbanization, and the aging of population is emerging. Degradation of the masticatory muscle due to aging and reduction of the number of mastications causes dry mouth syndrome with decreased saliva in the elderly. Changes in the amount and composition of saliva cause various oral diseases, especially, periodontal disease is closely related to the microorganisms that form the plaque. In the elderly education, stimulation saliva was collected at the first visit and the last visit to observe changes in microorganisms in the oral cavity. For the collection of the probes, the paraffin wax was chewed for 5 minutes. The samples were immediately refrigerated in a 50 cc plastic tube and then stored at -20°C until the next use. The subjects of this study were the elderly people aged 65 years or older, and the study was conducted on 16 persons, 3 males and 13 females. The distribution of saliva microorganisms according to rolling brushing method showed significant difference in all three groups (Aa & Red complex, Orange complex and Green complex) before and after the education. In the group who answered that they had dentures, it was confirmed that the amount of microorganisms before and after education was significantly reduced in all three groups. There was a significant decrease in the amount of microorganisms in the Aa & Red complex and Orange complex group in the case of hypertension related to systemic disease. In conclusion, the higher the interest of oral health and general health of the subjects, the more effective the education.
