“…A recent systematic review on the epidemiology of bruxism in adults retrieved only a couple of papers on AB, reporting a 22.1% prevalence, as defined by the frequency term “often”, and a 31% prevalence, independent on the frequency, during the past 6 months . A successive paper reported a 11.2% prevalence based on the generic history‐taking item “During the day, do you grind your teeth or clench your jaw?”, while an investigation on Brazilian dental students found a 36.5% prevalence, as identified by the question “In the last 30 days have you noticed clenching your teeth while awake and not chewing food?” …”

The aim of this study was to assess awake bruxism (AB) behaviours in a sample of healthy young adults using a smartphone-based application for a real-time report (ie, ecological momentary assessment [EMA], also called experience sampling method [ESM]). Forty-six dental students used a smartphone application that sent 15 alerts at random intervals during the day for 1 week to collect AB self-reports. They had to answer on time by tapping on the display icon that refers to their current condition of jaw muscles: relaxed; teeth contact; teeth clenching; teeth grinding; jaw clenching without teeth contact (ie, bracing). The average frequency of relaxed jaw muscles, as a percentage of answers over the 7 days, was 71.7%. Teeth contact (14.5%) and jaw clenching (10.0%) were the most frequent AB behaviours. No significant gender differences were detected. Interindividual differences were quite relevant, but the overall frequency was in general only moderately variable from day-to-day. Coefficient of variation (CV) was low for the condition "relaxed jaw muscles" (0.44). At the individual level, teeth contact was the most prevalent behaviour, with a 39.1%-52.2% proportion of subjects reporting it at least once a day. During a 7-day observation period, the frequency of real-time report of AB behaviours in a sample of healthy young adults was 28.3%. The low daily variability in the average frequency value for the relaxed jaw muscles condition suggests that EMA may be a reliable strategy to get deeper into the epidemiology of oral behaviours. This investigation introduced EMA principles to the study of AB and provided data on the frequency of AB behaviours in young adults that could be compared to populations with risk/associated factors and possible clinical consequences.

“…It is hypothesised that the close functional coupling of these muscle groups may be involved in the aetiology of myofascial pain conditions .

[15][16][17][18][19] Electromyographic (EMG) monitoring of the co-contraction behaviour of masticatory and neck muscles has been conducted under conditions of pathophysiologic loading of the masticatory muscles, for example jaw clenching or tooth grinding.

The objective of this study was to analyse the co-contraction behaviour of jaw and neck muscles during force-controlled experimental grinding in the supine position. Twelve symptom-free subjects were enrolled in the experimental study. Electromyographic (EMG) activity of semispinalis capitis, splenius capitis and levator scapulae muscles was recorded bilaterally with intramuscular fine-wire electrodes, whereas that of sternocleidomastoideus, infrahyoidal, suprahyoidal, masseter and anterior temporalis muscles were registered with surface electrodes. EMG and force measurements were performed during tasks simulating tooth grinding on custom-made intraoral metal splints. The mean EMG activity normalised by maximum voluntary contraction (% MVC) of each of the neck muscles studied during grinding was analysed and compared with previous data from jaw clenching at identical force (100 N) and (supine) position. The occurrence of low-level, long-lasting tonic activation (LLTA) of motor units was also documented. The mean three-dimensional force vector of the grinding forces was 106 ± 74 N. In the frontal plane, the incline to the midsagittal plane ranged between 10° and 15°. In the midsagittal plane, the incline to the frontal plane was negligibly small. Posterior neck muscle activity during grinding ranged between 4.5% and 12% MVC and during clenching with 100 N between 1.8% and 9.9% MVC. Masticatory muscle activity during grinding ranged between 17% and 21% MVC for contralateral masseter and ipsilateral temporalis and between 4% and 6.5% for ipsilateral masseter and contralateral temporalis. LLTA had an average duration of 195 ± 10 seconds. The findings from this study do not support pathophysiological muscle chain theories postulating simple biomechanical coupling of neck and jaw muscles. Co-contractions of neck and masticatory muscles may instead occur as a result of complex neurophysiological interactions.

“…Recently, it was shown that self-reported awake bruxism was associated with TMD pain complaints [14,15]. This observation can be supported by the results of experimental studies, which demonstrated that clenching can aggravate masseter muscle pain in patients with TMD [16].…”

Introduction. Bruxism, the most detrimental parafunctional activity of the masticatory system can cause various temporomandibular joint disorders, as well as masticatory muscle disorders. It is important to identify factors aggravating bruxism, which can be easily eliminated and ease control of the disorder.Aim. The aim of the study was to analyze the association between the use of common stimulants -nicotine, caffeine and selfreports of awake bruxism.Material and methods. 113 dental students (83 females, 30 males) aged 21-29 were examined. In order to diagnose awake bruxism subjects were asked questions from the Oral Behaviors Checklist. Patients were also asked about daily/weekly frequency of cigarette smoking and coffee as well as caffeine-containing beverages consumption.Results. Cigarette smoking was positively associated with self-reported awake bruxism. There was no link found between caffeine consumption and parafunctional activities.Conclusion. Cigarette smoking, but not caffeine consumption, may be a risk factor for awake bruxism. However, this association should be further assessed in the presence of confounding factors, such as psychological distress.

Association of temporomandibular disorder pain with awake and sleep bruxism in adults

Abstract: When occurring separately, awake and sleep bruxism are significant risk factors for TMD pain. In case of simultaneous presence, the risk for TMD pain is even higher.
