“…Bruxism is mostly present in children, with prevalence rates ranging from 14--17%, which decreases to around 12% in adolescents and 8% in adults (AASM, 2005). Like other parasomnias, genetic factors appear to be important, accounting for ~40% of liability to bruxism (Hublin et al 1998a), but episodes can also be triggered by precipitating factors such as anxiety and stressful life events (Ohayon et al 2001). Enuresis: Enuresis (bed--wetting) typically occurs in around a third of children four years of age, and is only considered problematic when symptoms persist beyond 5 years of age (AASM, 2005).…”

Sleep changes throughout the lifespan, with particularly salient alterations occurring during the first few years of life, as well as during the transition from childhood to adolescence. Such changes are partly the result of brain maturation; complex changes in the organisation of the circadian system; as well as changes in daily routine, environmental demands and responsibilities.Despite the automaticity of sleep, given that it is governed by a host of complex mechanisms, there are times when sleep becomes disturbed. Sleep disturbances in childhood are common and may stem from behavioural difficulties or abnormalities in physiological processes and, in some cases manifest into diagnosable sleep disorders. As well as occurring exclusively, childhood sleep disturbances often co--occur with other difficulties. The purpose of this chapter is to outline the neurobiology of typical sleep/wake processes, and describe changes in sleep physiology and architecture from birth to adulthood. Furthermore, common childhood sleep disorders are described as are their associations with other traits, including all of the syndromes presented in this handbook: ASDs, ADHD, schizophrenia, and emotional/ behavioural difficulties. Throughout, we attempt to explain possible mechanisms underlying these disorders and their associations.

“…SB is believed to be linked to problems such as; tooth wear and fractures of dental restorations, osteohypertrophy, muscle hypertrophy, temporomandibular joint and muscle pain, jaw locking, temporal headaches, and cheek-biting [5][6][7] although the evidence is scares for some of the proposed effects. The prevalence of SB is 8% in the normal adult population, decreases from 14% in childhood to 3% in the elderly and does not have gender differences [8][9][10][11].…”

Highlights AbstractAim: The choice of biomaterials for occlusal splints may significantly influence biological outcome. In dentistry, hard acrylic occlusal splints (OS) have been shown to have a temporary and inhibitory effect on jaw-muscle activity, such as tooth clenching and grinding during sleep, i.e., sleep bruxism (SB). Traditionally, this inhibitory effect has been explained by changes in the intraoral condition rather than the specific effects of changes in occlusion. The aim of this preliminary study was to investigate the effect of another type of occlusal surface, such as a soft-material OS in addition to a hard-type OS in terms of changes in jaw-muscle activity during sleep. Materials and Methods:Seven healthy subjects (mean ± SD, six men and one woman: 28.9 ± 2.7 year old), participated in this study. A soft-material OS (ethylene vinyl acetate copolymer) was fabricated for each subject and the subjects used the OS for five continuous nights. The EMG activity during sleep was compared to baseline (no OS). Furthermore, the EMG activity during the use of a hard-type OS (Michigan-type OS, acrylic resin), and hard-type OS combined with contingent electrical stimulation (CES) was compared to baseline values. Each session was separated by at least two weeks (washout).Jaw-muscle activity during sleep was recorded with single-channel ambulatory devices (GrindCare, MedoTech, Herlev, Denmark) in all sessions for five nights. Results: Jaw-muscle activity during sleep was 46.6 ± 29.8 EMG events / hour at baseline and Applied Surface Science 5 significantly decreased during the hard-type OS (17.4 ± 10.5, P = 0.007) and the hard-type OS + CES (10.8 ± 7.1, P = 0.002), but not soft-material OS (36.3 ± 24.5, P = 0.055). Interestingly, the soft-material OS (coefficient of variance = 98.6 ± 35.3 %) was associated with greater night-to-night variations than baseline (39.0 ± 11.8%) and the hard-type OS + CES (53.3 ± 13.7%, P < 0.013). Conclusion: The present pilot study in small sample showed that a soft-material occlusal splint does not seem to inhibit jaw-muscle activity during sleep. Within the limitation of the study, it appears that the choice of biomaterials for occlusal splints may have a significant impact on the neurobiological regulation of jaw-muscle activity during sleep.

Sabemos que a prevalência do BS é de 80-90% da população, com declínio linear conforme a idade de 19% -entre 3-10 anos -para 13% no adulto jovem e 3% na população com mais de 60 anos 13,14 .…”

RESUMO:Vários distúrbios do sono podem acompanhar a Síndrome da Apnéia do Sono pela concomitância das síndromes ou pela existência de mecanismos fisiopatológicos comuns. Destacamos a insônia, o bruxismo do sono e o sonambulismo.A insônia pode ser uma das queixas dos pacientes portadores de distúrbios respiratórios do sono, pela fragmentação do sono decorrente. Além disso, ambos podem trazer sérias repercussões na saúde como o aumento da morbidade cardiovascular e maior risco de acidentes automobilísticos e laborativos, como tem sido demonstrado nas duas ultimas décadas. O correto diagnóstico de insônia em pacientes com apnéia do sono, bem como de apnéia em pacientes com insônia define a metodologia propedêutica empregada e também o tratamento, como por exemplo, a abordagem farmacológica quando necessária e o tratamento do distúrbio respirató-rio concomitantemente.O bruxismo do sono pode estar presente em 3,5-14% dos pacientes com apnéia do sono. Na sua investigação clínica devemos sempre avaliar a possível presença da apnéia do sono já que para o seu tratamento muitas vezes é necessária a sua abordagem em primeiro lugar para então utilizarmos tratamentos farmacológicos e dispositivos que diminuam os danos às estruturas orofaciais.Dentre as parassonias que frequentemente acompanham a apnéia do sono temos o sonambulismo. Ele representa a presença de atividade motora típica da vigília durante estado do sono. Esse fenômeno torna-se mais freqüente quando ocorre fragmentação do sono, provocando dissociação das variáveis fisiológicas, como ocorre em indivíduos com distúrbios respiratórios do sono.Concluindo, é de suma importância o conhecimento e a identificação de outros distúrbios do sono que podem ocorrer como epifenômenos ou como conseqüência da apnéia obstrutiva do sono, pois tanto o tratamento dos mesmos pode, em alguns casos agravar a apnéia do sono, quanto o subdiagnóstico pode interferir na melhora clínica do paciente.
