| Outline of Final Research Achievements |
In order to clarify the clinical condition of the patient occlusal paresthesia (disease), the occlusal interference which cause occlusion discomfort artificially grant, and the state at that time to record the autonomic nervous activity and brain activity. The psychological tests were performed also to evaluate the mental before measurement. Method was repeated dental foil one by one, the grinding motion was a task. Subjects recorded the "foil perception threshold" and "occlusal discomfort occurs threshold", and shown their discomfort at that time by visual analog scale (VAS value). The simultaneous measurement of the autonomic nervous activity and brain activity (fNIRS) during tasks enforcement were carried out. The subjects were 19 patients (11 males, 8 women).
As a result, the autonomic nervous activity and higher brain function activities to the occurrence of occlusal discomfort has been suggested that there are closely related.
