Comparison of the inhibitory effects of oral appliances on sleep bruxism : A pilot study Comparison of the inhibitory effects of oral appliances on sleep bruxism : A pilot study 大森, 俊和 OOMORI, TOSHIKAZU 大森 OOMORI 俊和 TOSHIKAZU 朝日大学歯学部口腔機能修復学講座歯科補綴学分野 UNO, MITSUNORI 横矢, 隆二 YOKOYA, RYUZI 横矢 YOKOYA 隆二 RYUZI 朝日大学歯学部 Sleep bruxism oral appliances EMG Sleep bruxism (SB) is believed to be a masseter muscle activity caused by the central nervous system, thus distinguishing it from diurnal bruxism, which is thought to be an acquired behavior. Various local factors have been associated with the onset of SB, but a direct relationship with occlusion has been ruled out, whereas psychological stress is typically believed to be closely involved. The present study monitored both bruxist and non-bruxist subjects to observe their SB profiles and then compare and investigate the SB-inhibiting effects of several removable oral appliances. The subjects were teachers, undergraduate students, and postgraduate students from the Asahi University School of Dentistry. Informed consent was obtained from all subjects after carefully explaining the study aims and details. This study was conducted with the approval of the Asahi University School of Dentistryʼs Ethical Review Board (approval no. 22095). A comparison of the incidence of bruxism events when not wearing an oral appliance and when wearing the 3 types of appliances (thin plate, thick plate, SP) showed that the incidence decreased when wearing any of the 3 appliances relative to when no appliance was worn. Furthermore, a comparison of the event incidences of the 3 appliances demonstrated that the thin plate had the highest event incidence. 岐阜歯科学会 2021-10 eng departmental bulletin paper https://asahi-u.repo.nii.ac.jp/records/13737 2433-0191 AN00053070 岐阜歯科学会雑誌 The Journal of Gifu Dental Society 48 2 77 90 https://asahi-u.repo.nii.ac.jp/record/13737/files/gifushika482_7790_2021.pdf application/pdf 817.8 kB 2022-01-12
