The exact etiology of sleep-related bruxism remains controversial. No clear CNS pathology has been demonstrated in sleep-related bruxism. It seems to be a reaction to microarousals during sleep. It may occur concomitantly with other sleep disorders that are associated with an arousal, such as NREM parasomnias. Factors that have been proposed include:55Problems with dental occlusion (‘occlusal interferences').Stress and anxiety.Presence of excess systemic catecholamines/sympathetic activation.Conditions associated with increased arousals, such as smoking, caffeine use, and sleep-disordered breathing.
Treatment of Chronic Fatigue Syndrome
Published in Jay A. Goldstein, Chronic Fatigue Syndromes, 2020
The possible role of the amygdala in the pathogenesis of TMPDS is compatible with the limbic hypothesis of CFS. TMPDS is very common in the general population, and even more common in the CFS population, in whom it is often a premorbid disorder. Although I have often found it to be associated with mood disorders, many patients have severe bruxism with no past or family history of mood disorders. This may be a variant in limbic function, perhaps akin to panic disorder without panic.

Not surprisingly, this application was pioneered in the far east where masseter hypertrophy is a common but also unwanted racial feature. There should be no concern about masticatory function after the treatment, as the temporalis and pterygoid muscles will compensate for the reduction of masseteric function. This treatment can also be applied to cases of bruxism, although this indication is beyond the purpose of this chapter.

Neither of the self-reported SB and AB activities were significantly associated with perceived stress. However, stress levels of those with possible bruxism were slightly higher (Table 5). These observations are confirmed by a previous study of self-reported bruxism in a general population, which showed very similar but significant differences in emotional stress among bruxers and non-bruxers (Winocur et al. 2011). Early research of this topic indicated that stress and certain personality traits contribute to the etiology of bruxism (Fischer and O’toole 1993; Pingitore et al. 1991). Nevertheless, a systematic review on the subject concluded that wake-time clenching can be associated with psychosocial factors and a number of psychopathological symptoms but evidence to relate SB with psychosocial disorders is lacking (Manfredini and Lobbezoo 2009). Literature presents contradictory interpretations of the role of stress in the etiology of SB (Lavigne et al. 2008). One theory states that emotional stress interferes with the quality of sleep causing frequent transitions between sleep stages, while bruxism is a side-effect of these microarousals (Manfredini et al. 2005). Therefore, it is important to treat the results of epidemiological studies with caution, as, for example, in this case, the statistically insignificant influence of stress may be significant from a clinical point of view.

Technologies that associate diagnosis with treatment of bruxism have been little explored so far. In the future, it is necessary that the technologies to be developed have three objectives: that the devices can perform diagnosis of SB, differentiate primary or secondary bruxism, and differentiate the type of movement performed. So, it will be necessary for research to respond if the type of movement influences the damage caused by bruxism such as pain, fracture, tooth wear, and others.
Association of oral behaviours’ frequency with psychological profile, somatosensory amplification, presence of pain and self-reported pain intensity

Anxiety was found to be predictive of oral behavioural habits in the current study’s multiple regression model. Ahlberg et al. [38] discovered a link between self-reported bruxism and psychological states like anxiety or stress. According to one systematic review, the link between oral habits and anxiety is debateable. However, it appears that bruxism may be linked to some particular symptoms on the anxiety disorder spectrum [39].
