Outline of Final Research Achievements

The Sleep bruxism (SB) etiological mechanisms remain still unclear yet, thus, it is an important issue to elucidate the detail mechanisms of SB occurrence. There might be possible associations among the SB, above mentioned systemic movements and the micro-arousal, and the consideration of these associations would be helpful to clarify the SB mechanisms. Thus, we examined the detail associations among the occurrence of SB, body motion and sleep arousal. The mechanism such as nerve activities associated with leg movement and swallowing might be related to the aetiology of SB incidence.
