Sleep Bruxism

The aim of this study was to describe sleep habits and sleep problems in a population of undergraduates in Palestine. ... The fourth section contained 5 questions pertaining to parasomnia: sleep talking ( ST), sleep walking ( SW), bruxism ( B),

Rhythmic masticatory muscle activity (RMMA) is the characteristic electromyographic pattern of sleep bruxism (SB), a sleep-related motor disorder associated with sleep arousal. Sleep arousals are generally organised in a clustered mode known as the cyclic alternating pattern (CAP). CAP is the expression of sleep instability between sleep maintaining processes (phase A1) and stronger arousal processes (phases A2 and A3). This study aimed to investigate the role of sleep instability on RMMA/SB occurrence by analysing CAP and electroencephalographic (EEG) activities. The analysis was performed on the sleep recordings of 8 SB subjects and 8 controls who received sensory stimulations during sleep. Baseline and experimental nights were compared for sleep variables, CAP, and EEG spectral analyses using repeated measure ANOVAs. Overall, no differences in sleep variables and EEG spectra were found between SB subjects and controls. However, SB subjects had higher sleep instability (more phase A3

The aim of this cross-over, randomized, single-blinded trial was to examine whether intra-esophageal acidification induces sleep bruxism (SB). Polysomnography with electromyogram (EMG) of masseter muscle, audio-video recording, and esophageal pH monitoring were performed in a sleep laboratory. Twelve healthy adult males without SB participated. Intra-esophageal infusions of 5-mL acidic solution (0.1 N HCl) or saline were administered. The frequencies of EMG bursts, rhythmic masticatory muscle activity (RMMA) episodes, grinding noise, and the RMMA/microarousal ratio were significantly higher in the 20-minute period after acidic infusion than after saline infusion. RMMA episodes including SB were induced by esophageal acidification. This trial is registered with the UMIN Clinical Trials Registry, UMIN000002923.

Sleep bruxism (SB) in children may be related to headaches and causes extensive damage of primary teeth. This paper evaluates the incidence of SB in children from Itanhandu, MG, Brazil.|The presence of teeth wear facets was verified through clinical examinations on a sample of children, whose parents answered a questionnaire about their children's behavior and habits. Analysis of variance and chi-square tests (p=0.05) were applied to identify possible correlations between the presence of SB and the parents' responses to the questionnaire.|The sample comprised of 170 children, 51.76% (n=88) of which were girls, while the average age was 4.37 (1.69) years. A total of 15.29% (n=26) had been diagnosed as bruxers, 46.47% displayed restless behavior, and only 10% used medication. The average duration of breastfeeding was 4.4 (0.25) months. A positive correlation was found between restless behavior and the presence of SB (p<0.001). No correlation was found between

The biomechanical load during strong bruxism activity reportedly causes many dental/oral problems. However, it is unknown whether the magnitude of muscle activity during sleep is controllable. In this study, the relationship between the magnitude of muscle activity during sleep and types of tooth contacts was examined, including anterior and posterior guidance, in order to clarify how occlusion factors contribute to sleep bruxism (SB). An EMG-2-axis accelerometer system was used for monitoring patterns and activities of SB. Bruxchecker was used to evaluate tooth contacts during SB, and a condylograph was used to measure posterior guidance (sagittal condylar inclination). Results show that grinding rather than clenching or tapping was observed in the high SB group, and there was Incisor-Canine-Premolar-Molar (ICPM) tooth contact during SB grinding movement. The canine occlusal guidance (COG) was flatter in the low SB group than in the moderate SB group. Relative canine occlusal
