Outline of Final Research Achievements |
Nine adult volunteers (7 males and 2 females mean age 23.6 ± 3.5 year old)with no impairment of stomatognathic function were participated in this study. Their surface EMG of the masseter muscle was recorded with a portable EMG logging device for about 24 hours.We detected and classified non-unctional masseter muscle activities during awake and sleep bruxism as clenching, grinding, and mixed by using the same detection and classification criteria. The frequency, maximum masseter muscle activity, and duration of were compared between awake and sleep bruxism events. The awake bruxism events were significantly more frequent than the sleep bruxism events. There were no significant differences in the maximum masseter muscle activity and duration between the awake and sleep bruxism events. As a result this study, we revealed the characteristic nonfunctional masseter muscle activity patterns during the awake bruxism in the healthy adults.
