“…In this mode of assessment, subjects may be asked to monitor and report their behaviour in real time over a certain period of time (e.g., one or multiple weeks with or without interval time) after being informed of the possible conditions belonging to the spectrum of AB behaviours (i.e., clenching, bracing, thrusting, teeth contact habit) 76 . This multiple time‐point reporting in real time over an observation period can be performed through the use of pagers, paper diaries, or even smartphone apps 77–80 . Several studies recommended the use of such EMA strategies in the field of AB and compared it to single time‐point reports, such as the OBC 30,31 .…”

BackgroundWith time, due to the poor knowledge on it epidemiology, the need to focus on awake bruxism as a complement of sleep studies emerged.ObjectiveIn line with a similar recent proposal for sleep bruxism (SB), defining clinically oriented research routes to implement knowledge on awake bruxism (AB) metrics is important for an enhanced comprehension of the full bruxism spectrum, that is better assessment and more efficient management.MethodsWe summarised current strategies for AB assessment and proposed a research route for improving its metrics.ResultsMost of the literature focuses on bruxism in general or SB in particular, whilst knowledge on AB is generally fragmental. Assessment can be based on non‐instrumental or instrumental approaches. The former include self‐report (questionnaires, oral history) and clinical examination, whilst the latter include electromyography (EMG) of jaw muscles during wakefulness as well as the technology‐enhanced ecological momentary assesment (EMA). Phenotyping of different AB activities should be the target of a research task force. In the absence of available data on the frequency and intensity of wake‐time bruxism‐type masticatory muscle activity, any speculation about the identification of thresholds and criteria to identify bruxers is premature. Research routes in the field must focus on the improvement of data reliability and validity.ConclusionsProbing deeper into the study of AB metrics is a fundamental step to assist clinicians in preventing and managing the putative consequences at the individual level. The present manuscript proposes some possible research routes to advance current knowledge. At different levels, instrumentally based and subject‐based information must be gathered in a universally accepted standardised approach.

“…Bruxism was originally thought to be a central nervous system problem, associated with anxiety, tension, and the release of stressful [4]. Recent studies have shown that bruxism may be caused by a synergistic effect of multiple factors, such as genetic factors [5], neuropsychological factors (long-term anxiety and tension) [6,7], physiological and pathological factors (malocclusion, snoring, sleep disorder) [8][9][10][11], and bad lifestyle habits (smoking, alcoholism, excessive caffeine intake) [12][13][14][15].…”

[Objective] Occlusal splints are always applied on individuals with bruxism to reduce tooth wearand relieve orofacial symptoms such as myofascial pain. The stomatognathic system ismainly composed of tooth, occlusion, masticatory muscles, and temporomandibular joint. The occlusion and masticatory muscles function are regarded as the important parameters for evaluating the stomatognathic system state objectively. However, the effects of occlusal splints on individuals with bruxism is rarely elucidated from accurate neuromuscular analysis and occlusion evaluation. The aim of the present study was to estimate the effects of three different splints (two clinically common full coverage occlusal splint and an modified anterior splint) on subjects with bruxism using K7-J5 neuromuscular analysis system and Dental Prescale II (DP2) to evaluate occlusion. [Methods] Sixteen subjects claimed to be suffering from nocturnal bruxism,with complete dentition and stable occlusal relationship, were selected for study.The intermaxillary space and the baselines of EMG-activity of the anterior temporalis and masseter were recorded for all the subjects. The participants was treated with three different splints, and outcomes were estimated by comfort index, occlusion and surface electromyography of anterior temporalis and masseter. [Results] At teeth clenched position, EMG data were significantly lower in the participants with use of modified anterior splint than with hard, soft occlusal splint or without splint (p < 0.05). The maximum bite force and bite area occur in subjects without use of splint , while the minimal occur in subjects with use of modified anterior splint. Intermaxillary spaceincreased and masticatory muscles presented significant reduction of EMG data at rest position as a result of J5 (p < 0.05). [Conclusion] Modified anterior splint seems to be more comfortable and effective in reducing occlusion force andelectromyographic activity of anterior temporalis and masseter for subjects with bruxism.

“…Several factors are associated with TMJ clicking, such as awake bruxism and specific oral behaviours that create pressure on the jaw structures, a more sensitive somatosensory profiling to mechanical pain tests, and a less efficient pain modulation system. Besides, poor sleep quality along with higher levels of hypervigilance, pain catastrophising and kinesiophobia are also key characteristics in these patients 5,7–10 …”

“…sleep quality along with higher levels of hypervigilance, pain catastrophising and kinesiophobia are also key characteristics in these patients. 5,[7][8][9][10] Most patients with TMJ clicking do not seek treatment until pain develops or the clicking truly disturbs. 11 The perception, interpretation and reporting of TMJ sounds are particular of each individual.…”

Background Understanding the profile of the individual complaining of TMJ clicking can help in the clinical approach of these patients. Objective To identify clinical variables associated with individuals who complain about and seek treatment for TMJ clicking. Methods Seventy‐two individuals, composed the sample: Group 1 – patients with a complaint of TMJ clicking who sought treatment; (n = 36); Group 2 – individuals with TMJ clicking who have no complaints about it (n = 36). Three categories of data were evaluated: clinical (gender; age; side of TMJ clicking; TMJ pain; self‐reported level of bother; previous TMJ clicking information); somatosensory (mechanical pain threshold [MPT], wind‐up ratio [WUR], pressure pain threshold [PPT]); and, psychosocial (Pain Vigilance and Awareness Questionnaire [PVAQ]; Pain Catastrophising Scale [PCS]; Tampa Scale for Kinesiophobia for Temporomandibular Disorders [TSK/TMD]); The Perceived Stress Scale (PSS); The State‐Trait Anxiety Inventory (STAI). Results Group 1 was composed mostly of female patients, with TMJ pain, without previous orientation about the condition, bothered by the clicking, with lower PPT and higher scores in the PVAQ, PCS, TKS/TMD, PSS and STAI scales than Group 2. The groups did not differ significantly for side of TMJ clicking, age, MPT and WUR. Conclusion Individuals who have a TMJ clicking complaint and seek treatment are mostly female, have TMJ pain, have not received previous orientation about TMJ clicking, are bothered by the clicking, have a lower pain threshold and higher scores of hypervigilance, catastrophising, kinesiophobia, stress and anxiety than people with TMJ clicking who do not report it.
