Dental sleep medicine as a discipline was first described about a quarter of a century ago. Snoring, obstructive sleep apnea, sleep bruxism, xerostomia, hypersalivation, gastroesophageal reflux disease, and orofacial pain were identified as dental sleep-related conditions. This scoping review aimed to: i) identify previously unidentified dental sle...

Introduction: During sleep, limb and jaw muscle motor activity can be quantified by electromyography (EMG). The frequency of periodic limb activity during sleep increases with age in both the general and clinical research populations. The literature is controversial regarding stability, over age, of the frequency of rhythmic masticatory muscle act...

Chapter
Physical therapists (PTs) are among health professionals assessing and managing many rehabilitative conditions including pain. The main objective of this chapter is to clarify the role of PT in presence of pain and sleep complaints or disorders. In that way, management objectives would be directed not only toward pain but also to sleep. We first re...
Chapter
This book chapter proposes to review the more recent literature about sleep bruxism in its definition, epidemiological data, mechanisms, physiopathology, clinical presentation, diagnostic, complementary exams, and management. The target is also to show the association with other sleep and clinical disorders and to undo the confusion between sleep b...

Objective Systematic reviews on sleep bruxism (SB) as a comorbid condition of other sleep-related disorders are lacking. Such reviews would contribute to the insight of sleep clinicians into the occurrence of SB in patients with other sleep-related disorders, and into the underlying mechanisms of such comorbid associations. This systematic review a...

Introduction: Portable monitoring (PM) is an alternative to laboratory polysomnography (PSG) for diagnosing obstructive sleep apnea (OSA). However, PM tends to underestimate the apnea-hypopnea index (AHI), as it does not identify non-desaturating events associated with electroencephalographic (EEG) arousal. Objectives were to explore heart rate acc...
Article
Introduction Most of the studies that evaluate risk of dangerous driving in individuals with obstructive sleep apnea (OSA) examine the role of sleepiness. It is known that fatigue is also a very common complaint among drivers with OSA, however, fatigue and sleepiness are rarely examined separately when assessing risk for dangerous driving in this...
Article
This critical review focuses on obstructive sleep apnea (OSA) and its management from a dental medicine perspective. OSA is characterized by ≥10-s cessation of breathing (apnea) or reduction in airflow (hypopnea) ≥5 times per hour with a drop in oxygen and/or rise in carbon dioxide. It can be associated with sleepiness and fatigue, impaired mood an...
