[Saliva secretion and oral health in a hospitalized geriatric population in Israel]

Saliva secretion decreases with age, although not regarded as caused solely by age. The decrease is associated among others, with diseases and medications. The aim of the study was to assess saliva secretion, dentition and oral pathologies in a hospitalized geriatric population in a genera hospital. The secretion was measured by 2 methods: saliva collection at rest and sugar cube test. 125 patients agreed to participate, with an average age of 75. They had an average of 6 diagnoses, and took 6 medications. They had 6 teeth in average, with 52% edentulous. Salivary excretion was found to be 15% low according to the saliva secretion and According to the sugar cube test, 20% suffer from xerostomia. However, no statistically significant correlations were found to age, medications, diagnoses, or number of teeth. The study population was hospitalised for short term in a general hospital, and quickly returned to the community. Therefore, we can conclude that salivary excretion is low in the geriatric population in the community, especially among those who suffer from illnesses, who need short terms hospitalization. The health care personnel should be aware of this situation and recommend saliva substitutes and stimulants.
