To investigate the association between each clinical diagnosis criterion for sleep bruxism (SB) and the frequency of jaw motor events during sleep. Video-polysomnography was performed on 17 healthy adult subjects (mean age, 26.7 ± 2.8 years), with at least one of the following clinical signs and symptoms of SB: (1) a report of frequent tooth grinding, (2)(More)
STATEMENT OF PROBLEM Periodontal sensation in individuals with bruxism may differ from that in nonbruxers, as excessive amounts of occlusal force may be applied to the teeth during the night. However, this concept is not adequately addressed in the literature. PURPOSE The purpose of this study was to investigate the effects of bruxism on periodontal(More)
The purpose of this study was to investigate the effects of sleep bruxism on periodontal sensation and tooth displacement in the molar region. Twenty-eight (28) subjects lacking objective or subjective abnormalities in stomatognathic function were divided into two groups representing bruxers (n=14) and controls (n=14). Sleep bruxism was confirmed based on(More)

The purpose of this study was to investigate electromyography of the inferior heads of lateral pterygoid muscles in experimental displacement of mandible, and its clinical application for reproduction and diagnosis of mandibular position. In the experiments, the mandibular position was changed in vertical and horizontal directions and muscle activity of the(More)
The purpose of the study was to clarify the effect of a stabilization splint (SS) on the distribution of occlusal force around the dental arch during voluntary submaximal tooth clenching. Ten healthy volunteers participated in this study. For each subject, the maxillary SS was made of heat-cured hard acrylic resin with approximately one mm thickness at the(More)
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. A total of 35 university students and staff members participated in this study after providing informed consent. All participants were divided into either a sleep bruxism group (n = 21) or a control(More)
The aim of this study was to assess the acute effects of clonazepam and clonidine on rhythmic masticatory muscle activity in young adults with primary sleep bruxism, as well as accompanying effects on sleep architecture and cardiac activity. This study used a double-blind, crossover, placebo-controlled design. Polysomnography was performed on 19 subjects(More)
