| Outline of Final Research Achievements |
The aim of this study was to examine the possibility of reduction of orofacial pain and to investigate the modulation mechanism of orofacial pain by the taste and olfactory stimulation.The subjects of this study were patients with chronic orofacial pain that treaded in our department.All the subjects underwent gustatory test and olfactometric tests,and were evaluated with self-answerd type pain score(VAS), various psychological tests, autonomic activity analysis, and near-infrared spectroscopy.As a result, in all the subjects, orofacial pain intensity didn’t change by olfactory test. On the other hand, gustatory test by sweet taste decreased pain intensity（VAS）transient in the glossalgia patients.This study suggest that the sweet taste stimulation may have a transient pain reduction mechanism of glossalgia among orofacial pain.
