| Outline of Final Research Achievements |
Bruxism has adverse effects on the stomatognathic system, such as root fracture and temporomandibular joint disorders. However, the fundamental method of suppressing bruxism has not been reported much.
Previous studies have reported that the effect of auditory biofeedback during the day suppresses bruxism during the day and nighttime. However, the self-awareness state of bruxism during auditory biofeedback is unknown. Therefore, we used ecological momentary evaluation to record the self-awareness state of bruxism at the time of the alarm. We are also conducting electromyography evaluation at the same time as before. These results we reported how to classify bruxism based on the results of Combinational analysis of ecological momentary assessment and electromyography.

歯根破折や顎関節症を引き起こすブラキシズムですが根本的な治療法は確立されていません．本研究では側頭筋に筋電計を装着し，生態学的瞬間評価（EMA）としてランダムにアラームが発生する小型タブレットをもって日常生活を送ってもらいました．筋電計を側頭筋に装着することで頭髪等で隠すことができ，生活環境に配慮した研究を行うことができます．またEMA記録は小型タブレット内に搭載したアプリケーションにブラキシズムの程度をタップするだけとしました．簡便に日常に使用できることで，今後普及した際の取り入れやすさに配慮しました．これまで対症療法の治療法だけであった分野の新たな治療法となりうることが期待できます．
