“…Although some studies suggest that genetic polymorphisms, stress, anxiety, smoking, alcohol intake, drug abuse, sleep apnoea, sleep position and gastroesophageal reflux may be associated with SB, the exact pathophysiologic mechanisms underlying SB are still largely elusive . The current treatments for SB include occlusal splints, biofeedback, kinesiotherapy, and repetitive transcranial magnetic stimulation, electrical stimulation as well as drug intake such as clonidine .…”

Summary Background Most rhythmic masticatory muscle activities (RMMAs) have been shown to be accompanied with limb movements (LMs) in sleep bruxism (SB) patients during sleep. Objectives To compare the relationships between RMMAs and LMs in SB patients and normal subjects. Methods Polysomnographic recordings were performed on eight SB patients and nine normal subjects and the frequencies and durations of RMMAs as well as LMs were determined. Linear regression and correlation analysis were performed to study the relationship between durations of RMMAs and LMs when RMMAs occurred with LMs. Results Most LMs in SB patients, but not in normal subjects, were accompanied with RMMAs. RMMAs in SB patients were more likely to be isolated, phasic or mixed, while RMMAs in normal subjects were more likely to be tonic. The frequencies of LMs, isolated RMMAs and RMMAs accompanied with LMs in SB patients were significantly higher than those in normal subjects. Furthermore, linear regression and correlation analysis showed that duration of RMMAs was significantly associated with that of LMs when RMMAs occurred with LMs. The duration of RMMAs, when accompanied with LMs, in SB patients was significantly longer than that in normal subjects. Conclusions Close relationships between LMs and RMMAs exist in SB patients and normal subjects, and SB episodes may be part of cortical arousal responses and the increased cortical activities associated with SB episodes may not just be localised to the central nervous system (CNS) that controls jaw movements but may also include other parts of CNS that controls LMs.

“…Durante o sono, a RMMA está frequentemente associada ao movimento de deglutição e a aumentos no pH relacionados ao refluxo gastroesofágico, sendo mais pronunciada nos pacientes bruxômanos. A maioria desses eventos ocorrem na posição supina 24,25 . Deve ser considerado que uma parcela da população apresenta diagnóstico de BS por polissonografia apesar de não estar ciente e não relatar nenhum sintoma clínico.…”

IntroduçãoNa prática em saúde, o profissional deve estar ciente das condições do paciente de maneira integral, por isso o pleno conhecimento acerca de patologias frequentes, como a apneia obstrutiva do sono (AOS) e o bruxismo do sono (BS), é de grande importância.A etiologia dessas condições está sob constante investigação. A AOS está relacionada a interrupções no fluxo do ar na respiração durante o sono 1 , enquanto o BS tem sido associado cada vez menos à fatores periféricos, dando lugar à investigações sobre fatores centrais e cíclicos fisiológicos 2 . Tendo em vista o impacto da AOS e do BS na saúde e qualidade de vida dos pacientes 3 , é de suma importância compreendê-las e investigar o efeito de uma possível relação entre ambas.Este estudo tem como objetivo analisar a literatura acerca dessas patologias e traçar uma possível relação entre ambas, visando facilitar o seu diagnóstico na prática do cuidado em saúde. Objetivo: analisar a literatura acerca da apneia obstrutiva do sono (AOS) e do bruxismo do sono (BS) e traçar uma possível relação entre ambos. Revisão de literatura: a apneia obstrutiva do sono e o bruxismo do sono são patologias frequentes na prática médica e odontológica, e suas etiologias estão sob constante investigação. A AOS é caracterizada por episódios repetitivos

“…Of note, only about 10 % of the episodes of decreased esophageal pH (defi ned as a rapidly decreasing intraesophageal pH with a decrease of more than 0.4 per 2 s) included clenching episodes and the number of clenching episodes was independent of various sleep positions [ 154 ]. More specifically, it was found that RMMA is a secondary event to gastroesophageal refl ux occurring via sleep arousal and often associated with swallowing [ 39 ].…”

“…Furthermore, RMMA events including SB were induced by esophageal acidifi cation [ 155 ]. It has been proposed that preventing gastroesophageal refl ux and avoiding sleeping in a supine position might be effective in decreasing the frequency of SB [ 154 ]. Overall, the physiologic link between SB, the increase in salivation and the association with gastroesophageal refl ux requires further investigation.…”
