“…There is evidence that rhythmic masticatory muscle activity is associated with a higher amplitude of respiration within arousal . Similar results have also been obtained by Kato et al (2013a) who show that in patients with OSA the contraction of masseter muscle after respiratory events can be a nonspecific motor phenomena, dependent on the duration of arousals, rather than the occurrence of respiratory events. Those authors demonstrated that the activity of masseter muscles, following arousal episodes due to obstructive sleep apnea, does not differ from the activity of those muscles after spontaneous arousal.…”

Obstructive sleep apnea (OSA) syndrome is a sleep-related breathing disorder, due mainly to peripheral causes, characterized by repeated episodes of obstruction of the upper airways, associated with snoring and arousals. The sleep process fragmentation and oxygen desaturation events lead to the major health problems with numerous pathophysiological consequences. Micro-arousals occurring during sleep are considered to be the main causal factor for night jaw-closing muscles activation called bruxism. Bruxism is characterized by clenching and grinding of the teeth or by bracing or thrusting of the mandible. The causes of bruxism are multifactorial and are mostly of central origin. Among central factors there are secretion disorders of central nervous system neurotransmitters and basal ganglia disorders. Recently, sleep bruxism has started to be regarded as a physiological phenomenon occurring in some parts of the population. In this article we present an evaluation of the relationship between OSA and sleep bruxism. It has been reported that the frequency of apneic episodes and that of teeth clenching positively correlates in OSA. However, clinical findings suggest that further studies are needed to clarify sleep bruxism pathophysiology and to develop new approaches to tailor therapy for individual patients with concomitant sleep bruxism and OSA.

“…[9][10][11][12] On the other hand, recent studies have suggested that, in patients with OSAS, the activation of masseter muscles after respiratory events could be an unspecific motor activity that depends on the duration of sleep arousal rather than a response to respiratory events. 34 The majority of epidemiological studies on the association between OSAS and SB have recruited patients with OSAS to report on the prevalence of SB. Sjöhlm et al have studied 21 patients with OSAS and have found a sleep bruxism prevalence of 54% and 40% in patient with mild (AHI < 15) and moderate (AHI ≥ 15) OSAS, respectively.…”

Bruxism is an oral pathology of interest not only for dentists but also for specialists in sleep disorders. Sleep bruxism (SB) has been associated with obstructive sleep apnea syndrome Study Objectives: To estimate the frequency of obstructive sleep apnea syndrome (OSAS) in dental patients with tooth wear, and to assess the role of dentists in the identifi cation of patients at risk of OSAS. Methods: Dental patients with tooth wear and treated with occlusal splint were prospectively recruited to perform sleep study. The severity of tooth wear was established by the treating dentist before patient referral to sleep disorders unit. Sleep questionnaires, anthropometric measurements, and validated respiratory polygraphy were performed. Results: All patients with dental wear were offered a sleepiness analysis. Of 31 recruited patients, 30 (77% males) participated in this study. Patients' mean age was 58.5 ± 10.7 years (range: 35-90 years) and the body mass index was 27.9 ± 3.4 kg/m 2 . Tooth wear was mild in 13 patients, moderate in 8and severe in 9. The mean apnea-hypopnea index (AHI) was 32.4 ± 24.9. AHI < 5 was reported in 2 patients, AHI of 5-29 in 17, and AHI ≥ 30 in 11. A statistically signifi cant association was found between AHI severity and tooth wear severity (Spearman R = 0.505; p = 0.004). Conclusions:Tooth wear could be a tool to identify those patients at risk of having OSAS. This highlights the importance of dental professionals to identify and refer patients with OSAS.

“…Um sono com grande quantidade de episódios de despertares é denominado sono fragmentado e pode acarretar em problemas diurnos da falta de sono reparador, problemas esses observados em pacientes com AOS 19,38,39 . Kato et al 33 (2013) observaram uma frequência de 52% a 68% de despertares relacionados a eventos respiratórios em pacientes com AOS, sendo que, quando estava associado a um despertar, o evento respiratório levava a uma dessaturação de oxigê-nio transitória mais intensa. A sonolência diurna (sintoma conhecido da AOS) aparece como um fator predisponente independente para BS 15 .…”

“…Mais recentemente, Kato et al 33 (2013) sugeriram que contrações dos músculos masseter e temporal, após eventos respiratórios, podem ser fenômenos motores não específicos dependentes mais da duração dos despertares do que da ocorrên-cia dos eventos respiratórios, tendo em vista que essa musculatura era raramente ativada após os eventos, mas sua resposta aumentou significativamente em associação à duração dos despertares.…”

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
