Summary

This case-control study will evaluates the association between the definitive sleep bruxism diagnosis by gold-standard polysomnography examination obtained at Pelotas Sleep Institute and the sociodemographic, occupational, clinical conditions, sleep quality, sleep structure and Epworth sleepiness scale variables.

Conditions

  • Sleep Bruxism, Adult

Interventions

Polysomnography

The polysomnography (referred to as type I) allows assessing several sleep physiologic parameters (eg, EEG, electrooculogram, electromyogram, electrocardiogram, airflow, respiratory effort, oxygen saturation), whereas audio-video recording enables documenting tooth-grinding sounds and distinguishing between rhythmic masticatory muscle activity (RMMA) and orofacial (eg, swallowing) and other muscular activity (eg, head movements) during sleep. Based on the RMMA index (number of episodes per hour of sleep), sleep bruxism is diagnosed when RMMA episodes are greater than or equal to 2 (low-frequency SB, mild bruxism) or RMMA episodes are greater than or equal to 4 (high-frequency SB, severe bruxism)
