| Outline of Final Research Achievements |
The purpose of this study is to examine the relationships of neuropeptide to upper digestive tract function, autonomic nervous activity, and sleep bruxism. Cross sectional and Prospective Study were conducted with 15 patients with sleep apnea syndrome (OSAS), 9 patients with sleep bruxism, 5 microgenia patients, and 9 normal subjects.
The OSAS, bruxism, and microgenia patients suggested by significantly higher degree of the Tmax of the 13C-acetate breath test, the arousal index, the LF/HF ratio and the irregularity of gastrointestinal activity rhythm, than for the normal occlusion subjects. The relation between bruxism and neuropeptide and hormones such as cortisol, ghrelin, leptin, oxytocin were suggested. The bruxism episode decreased after treatment of each primary disease.
