| Research Abstract |
This study provides two conclusions.
1.The study indicates that clenching that occurs during normal activity is associated with a high level of anxiety. It also shows that the total level of muscle activity associated with clenching is 3.5 times greater than the level of muscle activity associated with none-clenching.
2.The study revealed that accurate monitoring of clenching requires that electromyography be used as an objective evaluation tool. In contrast, surveys might produce inaccurate results as they rely on individual subjective observations.
Based on the aforementioned study results, masticate muscle relaxation training was scheduled to be conducted. However, the training was discontinued because of the difficultly in collecting data due to east Japan earthquake disaster. Although funding support will soon end, we are considering restarting the study and plan to publish the results.
