“…While the advantages of this approach may be intuitive to researchers involved in the field, it must be pointed out that it may also influence the future construct of bruxism. For years, bruxism has been generically called into cause as a risk factor for several clinical consequences of dental interest, but the literature has always failed to show a clear‐cut relationship with the purported effects, such as TMDs, occlusal trauma, implant failures . Such observations led to a sense of urgency towards the need of redefining bruxism and discriminating between the different bruxism behaviours …”

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.

“…The researchers suggested that bruxism could be considered a marker for chronic stress [41]. Although the impact of bruxism on periodontal health has no consensus [41], it seems to be an aggravating factor for advanced periodontitis [42] even if it has little or no influence on a healthy periodontium or early-stage periodontitis [43].…”

--Introduction: Periodontal diseases are caused by pathogenic microorganisms that induce increases in of local and systemic proinflammatory cytokines, resulting in periodontal damage. The onset and evolution of periodontal diseases are influenced by many local and systemic risk factors. Educational objective: In this article, we aim to review the results of the research on the impact of chronic stress on the occurrence, development, and response to periodontal disease treatments and on the pathophysiological mechanisms of periodontal disease. Conclusion: Chronic stress has a negative impact on the occurrence, development, and response to the treatment of periodontal disease via indirect actions on the periodontium. This can result from behavioral changes caused by stress (poor dental hygiene, smoking, etc.) and a direct neuroimmunoendocrinological action related to the consequences (particularly immunological) of the secretion of certain chemicals (e.g., cortisol) induced by the activation of the hypothalamus and the autonomic nervous system in response to stress. These factors necessitate multidisciplinary management (e.g., physician, oral surgeon, and psychologist) of patients to identify subjects with chronic stress and to employ countermeasures to decrease the impact of stress on the periodontium.

Objectives To synthesise available knowledge about both sleep (SB) and awake bruxism (AB) as depicted by previous published systematic reviews (SR). Methods SR investigating any bruxism‐related outcome were selected in a two‐phase process. Searches were performed on seven main electronic databases and a partial grey literature search on three databases. Risk of bias of included SR was assessed using the “University of Bristol's tool for assessing risk of bias in SR”. Results From 1038 studies, 41 SR were included. Findings from these SR suggested that (a) among adults, prevalence of AB was 22%‐30%, SB (1%‐15%), and SB among children and adolescents (3%‐49%); (b) factors consistently associated with bruxism were use of alcohol, caffeine, tobacco, some psychotropic medications, oesophageal acidification and second‐hand smoke; temporomandibular disorder signs and symptoms presented a plausible association; (c) portable diagnostic devices showed overall higher values of specificity (0.83‐1.00) and sensitivity (0.40‐1.00); (d) bruxism might result in biomechanical complications regarding dental implants; however, evidence was inconclusive regarding other dental restorations and periodontal impact; (e) occlusal appliances were considered effective for bruxism management, although current evidence was considered weak regarding other therapies. Conclusions Current knowledge from SR was mostly related to SB. Higher prevalence rates were found in children and adolescents than in adults. Associated factors and bruxism effects on stomatognathic structures were considerably heterogeneous and inconsistent. Overall good accuracy regarding portable diagnostic devices was found. Interventions' effectiveness was mostly inconclusive regarding the majority of available therapies, with the exception of occlusal appliances.
