In this second part of a diptych on bruxism, the focus is on the associations of this masticatory muscle activity with other sleep-related conditions. Its association with the obstructive sleep apnoea syndrome (OSAS) has been a particular object of study. Bruxism seems to play a protective role in OSAS, although the evidence for this is not yet conclusive. Apart from this possible positive consequence, bruxism also has several negative consequences, for which evidence is available to a greater or lesser extent...

Patients who present to the general dentist's office with complaints of temporomandibular joint pain may exhibit signs and symptoms such as muscle soreness, bruxism, joint soreness, limited range of movement, altered movement, and facial pain as well as tooth chipping or tooth movement. After examinations, radiographic evaluations, and a review of medical history, dentists may have a bias toward regarding these symptoms as oral or dental in origin. After a diagnosis of a temporomandibular disorder (TMD), bruxism, or muscular spasms due to occlusal instabilities is established, the treatment protocol often includes an oral appliance (such as a nightguard), exercises, and pharmacologic agents...

Bruxism is a diurnal or nocturnal parafunctional activity that includes unconscious clenching, grinding, or bracing of the teeth. An extensive medical history should be taken in these patients so proper diagnosis can be made. Habits such as biting the tongue, cheeks or lips, chewing gum or eating seeds for many hours per day, biting nails, and/or biting hard objects, will cause and/or exacerbate pre-existing bruxism. The etiology of bruxism is uncertain, but it is hypothesized to be associated with genetic, structural, and psychosocial factors...

M C J Knippels, I M M Essers, F J H Magdelijns, D J L van Twist
BACKGROUND: The use of 4-fluoroamphetamine (4-FA) has shown a marked increase, especially because users perceive its effects to be relatively mild. 4-FA is also known as ecstacy-light, but is probably not as light as its name suggests. From April 2017 its use has therefore been forbidden in the Netherlands. CASE DESCRIPTION: In a short time, we saw three patients at our emergency department who had signs of a severe intoxication with 4-FA. A 21-year-old male developed a tonic-clonic seizure, bruxism, mydriasis, and rhabdomyolysis...

Since the publication of a special issue on bruxism of the NTvT in July 2000, consensus has been reached on bruxism's definition as a repetitive masticatory muscle activity that is characterised by clenching and/or grinding while awake (awake bruxism) or during sleep (sleep bruxism). As yet, however, no consensus exists about the diagnosis of bruxism: sufficient evidence to establish the reliability and validity of the commonly used techniques (self-report, clinical examination, imaging, electromyography, polysomnography) has not yet been produced...

PATIENTS: High or excessive parafunctional jaw muscle activity is a frequent complication of acquired brain injury (ABI) and may have some similarities to bruxism. Bruxism has been associated with increased tooth wear, masseter hypertrophy and headaches. The aim of this observational study was to identify the levels of jaw muscle activity from fourteen ABI patients having different functional and cognitive levels in their early phase of neurological rehabilitation (according to their Ranchos Los Amigos Scale (RLAS) score)...

Bruxism is defined as repetitive activity of the masticatory muscles, characterized by clenching the teeth or teeth grinding and/or by tapping and swaying. This study investigated sleep bruxism. The etiology is multifactorial: mainly central (neuropathic disorder, anxiety) but also genetic and local (posture, mouth breathing). The diagnosis is based primarily on the anamnesis and examination of dental wear and progression over time (photos and dental castings). A diagnostic guide is proposed in this article...

BACKGROUND: Polysomnography (PSG) is the gold standard for sleep bruxism (SB) assessment. High economical costs, complex technical equipment, and unfamiliar laboratory setting limit its use in children. AIM: To determine the night-to-night variability of electromyography (EMG) episodes during a five-night recording with the GrindCare Measure (GCM), and the agreement in the assessment of masticatory muscle activity (MMA) between GCM and PSG in children. DESIGN: Forty-seven children from clinics of Universidad CES participated...

Rhinitis, allergic or non-allergic, is an inflammatory condition of the nose. It is associated with a wide range of sleep disorders that are generally attributed to nasal congestion and presence of inflammatory mediators like cytokines and interleukins. However, the pathophysiological mechanisms behind these sleep disorders remain unclear. On the other hand, the trigeminocardiac reflex (TCR) has recently been linked to various sleep disorders like obstructive sleep apnea, sleep bruxism and rapid eye movement (REM) sleep apnea...
