| Outline of Final Research Achievements |
The aim of this study was to investigate the association between patterns of jaw motor activity during sleep and clinical signs and symptoms of sleep bruxism.
Sleep bruxism subjects with reported grinding sounds had a significantly higher total number of phasic episodes with grinding sounds than subjects without reported grinding sounds or controls. Similarly, sleep bruxism subjects with tooth attrition exhibited significantly longer phasic burst durations than those without or controls. Furthermore, sleep bruxism subjects with morning masticatory muscle fatigue or tenderness exhibited significantly longer tonic burst durations than those without or controls. These results suggest that each clinical sign and symptom of sleep bruxism represents different aspects of jaw motor activity during sleep.
