| Outline of Final Research Achievements |
There are various patterns of muscle activity in sleep bruxism (SB), the diagnosis of SB has been lumped together without taking into account the amount of activity in each pattern, and therefore, accurate treatment has not been provided. Based on the previous study by the applicants, which showed that clonidine suppressed SB, this study was conducted to verify the effect of clonidine on suppression and EEG activity for each physiological pathological classification of SB, which could be obtained by using polysomnography (PSG). However, due to the spread of the new coronavirus infection, it has become difficult to perform PSG with the subjects taking clonidine and controlling their physical condition. Therefore, we focused on biofeedback therapy using vibration stimulation, which is expected to have a suppressive effect on SB without using drugs with possible side effects.

睡眠時ブラキシズム(SB)は，睡眠中の非機能的な顎運動であり，顎口腔系の諸器官に様々な悪影響を及ぼし，補綴歯科領域における患者のQuality of lifeの低下を招く原因である．本研究は睡眠ポリグラフ検査(PSG)を用いることで得られるSBの生理学的病態分類ごとの抑制効果・脳波活動への影響を検証し薬剤によるSB抑制効果発現メカニズムの解明につながる知見を得るためのものである．
