| Outline of Final Research Achievements |
Sleep bruxism (SB) is defined as: ‘an oral parafunction characterized by grinding or clenching of the teeth during sleep that is associated with an excessive (intense) sleep arousal activity’. Clinical diagnosis of SB is generally made based on information gathered through medical interviews and clinical examinations, such as reports of tooth-grinding sounds during sleep, orodental findings such as tooth attrition, morning symptoms of masticatory muscle pain, fatigue or stiffness and masseter muscle hypertrophy. One important question is whether these signs and symptoms represent SB accurately. To answer this question, we investigated the associations between masseter muscle activity patterns during sleep and clinical diagnostic criteria for sleep bruxism(SB).

| Academic Significance and Societal Importance of the Research Achievements |
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，チェアサイドより収集されるSBの臨床情報と睡眠ポリグラフ検査(PSG)を用いることで得られるSBの生理学的病態との関連性を明らかにすることで，患者個々の筋活動状態を反映した症型分類に基づく臨床診断法の確立を目指し，個別化医療を実践するためのものである.
