| Outline of Final Research Achievements |
We analyzed brain activity with MEG to establish a method for objective evaluation of correlation between discomfort and intensity of occlusal contacts. Oral somatosensory was stimulated. As a result, power value of alpha waves during rest and closing eyes was reduced by continuous mechanical stimulation on the periodontal membrane. The activity was generated in the centriciput- occiput region. It was suggested that this method was effective to cause discomfort on periodontal membrane.
