“…Subjective report of tooth grinding can be over-estimated in patients with TM disorders (TMD), stress, and/or anxiety, the conditions that put one at risk of poor sleep quality: high correlations with self-reported SB were found to diminish when SB was assessed more objectively. [49][50][51] Tooth wear can be severe not only in patients with SB but also in patients with OSA, TMD and/or gastro-oesophageal reflux. 52 Morning headache and jaw symptoms can often be associated with primary snoring, OSA and primary insomnias.…”

We spend a significant proportion of our lives sleeping. Unfortunately, some of us suffer from sleep disorders, which can affect quality of life considerably. While most sleep disorders should be diagnosed and treated by medical doctors, it becomes increasingly clear that some disorders have important diagnostic and/or management links to the dental domain, hence the emergence of the discipline 'Dental Sleep Medicine' in dentistry. Dental Sleep Medicine is concerned with the study of the oral and maxillofacial causes and consequences of sleep-related problems. 1 Already more than twenty years ago, Prof. Lavigne and coworkers published a comprehensive review, entitled 'Sleep disorders and the dental patient', in which several common sleep disorders of interest

“…However, some events are characterised by stereotypic movements showing rhythmic and/or coordinated natures. In patients with sleep‐related abnormal movements, rhythmic movements often occur in the limbs and jaw, such as alternating rhythmic leg movements (Chervin, Consens, & Kutluay, ), rhythmic jaw‐closing muscle activity (Haraki et al., in press; Lavigne et al., ) and rhythmic and repetitive movements in the limbs (pedalling and bicycling) and jaw (mouthing) (Tassinari et al., ). The current hypothesis on the putative mechanisms for rhythmic limb and jaw movements during sleep proposes the involvement of a central pattern generator (CPG), which organises intrinsic rhythm activity related to mastication and locomotion (Guertin, ; Kato, Masuda, Yoshida, & Morimoto, ; Lavigne, Kato, Kolta, & Sessle, ; Tassinari et al., ).…”

“…Sleep bruxism is a prevalent sleep‐related movement disorder (Kato, Velly, Nakane, Masuda, & Maki, ) and is characterised by the frequent occurrence of rhythmic jaw‐closing muscle activities during NREM sleep (Tsujisaka et al., ). Human studies indicated an increase in masticatory CPG activity during NREM sleep in patients with sleep bruxism (Carra et al., ; Haraki et al., in press; Kato et al., ; Lavigne et al., ). The location of the neurons that constitute CPG was previously suggested to be in the brainstem reticular formation in the pons and medulla (Lund & Kolta, ; Nakamura & Katakura, ).…”

Rhythmic jaw muscle activities frequently occur during non‐rapid eye movement sleep in patients with sleep bruxism. The present study aimed to investigate the response characteristics of the masticatory rhythm generation during non‐rapid eye movement sleep in animals. Eleven guinea pigs were surgically prepared for polygraphic recordings by electromyography, electrooculography, electroencephalography and electrocardiography with the implantation of a stimulating electrode. Repetitive electrical microstimulations at three intensities were applied to the corticobulbar tract under freely moving conditions. The rhythmic electro‐myographic responses of the digastric and masseter muscles were scored and analysed. Changes in cortical electro‐encephalographic power and heart rate in association with these stimulations were quantified. Microstimulations to the corticobulbar tract induced rhythmic jaw muscle activities in digastric muscles, occasionally with masseter activities during wakefulness and non‐rapid eye movement sleep. The response rate of rhythmic jaw muscle activities was significantly lower (p < 0.01) and the response latency was significantly longer (p < 0.01) during non‐rapid eye movement sleep than during wakefulness. At higher stimulus intensities, the response rate increased and response latency decreased. The mean burst intervals of the digastric and masseter muscles were similar regardless of vigilance states and stimulus intensities. Induced rhythmic jaw muscle activities during non‐rapid eye movement sleep were followed by a transient decrease in delta power and increases in beta power and heart rate. During non‐rapid eye movement sleep, the masticatory motor system is able to generate rhythmic outputs to the jaw muscles in response to facilitatory inputs although the responsiveness was decreased from wakefulness.

“…It is also important to clarify whether this relationship with bodily movements is characteristic of RMMA since the motor patterning of RMMA and bodily movements may be supplemental information that can be used to improve detection of RMMA using ambulatory devices for the diagnosis and management of SB. Patients with SB exhibit RMMA and non-rhythmic masticatory muscle activities during sleep [23,24]. Although these two types of jaw motor activities may be activated by distinct neural elements in response to arousal [10,14,15,24], it remains unclear whether the relationship with bodily movements differentiates RMMA from nonspecific masseter activity (NSMA).…”

Purpose: The aims of the present study were to investigate the temporal relationships between jaw and bodily movements and clarify motor processes in the genesis of rhythmic masticatory muscle activity (RMMA) in sleep bruxism (SB). Methods: Video-polysomnography recordings were obtained from ten subjects with SB (mean age: 23.4 ± 1.6 years) and ten matched normal controls (CTL) (mean age: 24.4 ± 3.2 years). RMMA and nonspecific masseter activity (NSMA) were scored in association with bodily movements in the leg, arm, head, and trunk using electromyography and video recordings. The relationship between oromotor episodes and bodily movements was assessed in terms of sleep stage distributions and temporal relationships. Cardiac changes preceding oromotor episodes in stage N2 were assessed. Results: Approximately 80% of RMMA and NSMA were associated with movements in one or more body sites. RMMA and NSMA were more frequently associated with movements of the leg (70-75%) and arm (40-55%) than movements of the head (17-22%) and trunk (5-25%). The relationship between oromotor episodes and bodily movements did not significantly differ among sleep stages. Oromotor episodes and bodily movements did not show a consistent temporal pattern in the SB and CTL groups. Regardless of the temporal relationship between oromotor episodes and bodily movements, the mean heart rate significantly increased by 5 beats before the onset of oromotor episodes. Conclusions: No specific temporal motor patterns were found between RMMA and bodily movements. RMMA and NSMA represent a repertoire of arousalrelated autonomic motor responses during sleep.
