Clinical Condition and Sleep Quality Factors Associated With Sleep Bruxism in Adults.

2019-07-15 10:05:28 | BioPortfolio


This cross-sectional study will evaluate the association between sociodemographic, occupational, clinical conditions, psychological (sense of coherence), sleep quality variables and SB diagnosed by PSG, the gold standard exam with audio-visual resources obtained at Pelotas Sleep Institute.


Sleep bruxism is defined as a masticatory muscle activity during sleep that is characterised as rhythmic (phasic) or non-rhythmic (tonic) and should be considered a risk factor rather than a disorder in otherwise healthy individuals.

The diagnosis of sleep bruxism often is challenging and despite the use of questionnaires, clinical exams and portable devices, based on current knowledge, the polysomnography with audio-video recordings emerges as the gold-standard criteria for a definite sleep bruxism diagnosis.

Included on the questionnaire there is a registration form, which contains: included: age at time of data collection , gender, marital status , and education level ; Occupational: individuals were asked about work outside home, and working hours; Clinical condition: body mass index, smoking; alcohol consumption; use of sleeping pills; respiratory allergy and Psychological: sense of coherence .

Medical and Biotech [MESH] Definitions

A sleep disorder characterized by grinding and clenching of the teeth and forceful lateral or protrusive jaw movements. Sleep bruxism may be associated with TOOTH INJURIES; TEMPOROMANDIBULAR JOINT DISORDERS; sleep disturbances; and other conditions.

The time it takes to reach REM SLEEP. It is typically measured by POLYSOMNOGRAPHY or EEG as a part of various sleep pattern tests (e.g., multiple sleep latency test).

Simultaneous and continuous monitoring of several parameters during sleep to study normal and abnormal sleep. The study includes monitoring of brain waves, to assess sleep stages, and other physiological variables such as breathing, eye movements, and blood oxygen levels which exhibit a disrupted pattern with sleep disturbances.

Periods of sleep manifested by changes in EEG activity and certain behavioral correlates; includes Stage 1: sleep onset, drowsy sleep; Stage 2: light sleep; Stages 3 and 4: delta sleep, light sleep, deep sleep, telencephalic sleep.

Dyssomnias (i.e., insomnias or hypersomnias) associated with dysfunction of internal sleep mechanisms or secondary to a sleep-related medical disorder (e.g., sleep apnea, post-traumatic sleep disorders, etc.). (From Thorpy, Sleep Disorders Medicine, 1994, p187)
