| Outline of Final Research Achievements |
I examined whether sleep bruxism (SB) decreases by improvement of lifestyle by sleep hygiene instruction. As a result of giving sleep hygiene guidance to a SB patient in the previous study, Rhythmic Masticatory Muscle Activity (RMMA), which is an index of SB, is 8.4 times / h to 3.3 times / h decreased using a simple sleep recording device. As a result of performing sleep measurement at home for 3 SB patients (1 male, 2 females, average age 25.3 years) after 1 week of sleep hygiene instruction, one person drastically reduced to 6.8 h at 0 / h, one increased slightly from 3.7 / h to 4.4 / h, and the other increased sharply from 3.4 / h to 14.1 / h.

| Academic Significance and Societal Importance of the Research Achievements |
睡眠衛生指導が奏効するまでには時間がかかることもあり、今後は長期的な効果やResponderとNon-responderについて検証していく必要はあるが、本研究では睡眠衛生指導によるSBの減少効果の可能性が示唆された。このことより、SB患者に遭遇した場合、すぐにナイトガードを適応するのではなく、まずはより安全な保存治療である睡眠衛生指導を行い、ResponderのSBのコントロール促すべきである。
