| Outline of Final Research Achievements |
NCDs are the major cause of increased medical expenses. We attempted to estimate the relationship between oral health and medical expenses. Subjects consisted of teachers and staff members in prefectural senior high schools. The salivary levels of lactate dehydrogenase and haemoglobin were adopted as biomarkers to assess the periodontal diseases. After salivary tests, data for the medical expenses were provided by the mutual association of the public schools on an individual basis. Curve-fit estimations were then performed where medical expenses were used as a dependent variable and age or salivary levels of haemoglobin or lactate dehydrogenase were used as independent variables. However, no good fitness was obtained. Subsequently, multilayer perceptron neural networks were applied. With the neural networks, good fitness was obtained by using lactate dehydrogenase as an independent variable. The results of this study show that oral health is correlated with total medical expenses.
