Le diagnostic du bruxisme du sommeil

Abstract : Sleep bruxism (SB) may be defined as repetitive jaw-muscle activity characterized by clenching or teeth grinding and/or bracing or even thrusting the mandible during sleep. It has been receiving increased attention because of its association with dental, periodontal, articular, and facial complications. However, for clinician its diagnosis is most often done empirically, based on clinical signs, such as dental wear, to which certain anamnestic data aiming at detecting episodes of dental grinding are sometimes associated. This procedure is carried out most often without real knowledge of the pathophysiology of this disorder. A first part of this work is then devoted to reminders allowing to better understand its complexity and its interaction with certain phases of sleep. Otherwise, most studies that look at SB also determine its presence according to some criteria of the International Classification of Sleep Disorders (ICSD-3) proposed by the American Association of Sleep Medicine (AASM). To test the accuracy of these criteria we carried out a systematic review of the literature in a second part of this work. Because there is considerable heterogeneity in the results, this last one concluded that the application of ICSD3 for SB clinical diagnosis may be limited and it’s rather the absence of signs and symptoms that make possible to distinguish individuals who do not have SB. Finally, a third part was devoted to the report of a clinical case in order to better appreciate the complexity, the time and the cost of a polysomnography wich to date is the only one to allow a reliable diagnosis for the SB (gold standard).
