Self-reported sleep bruxism among Finnish symphony orchestra musicians: Associations with perceived sleep-related problems and psychological stress

Objective: This study aimed to evaluate whether self-reported sleep bruxism among musicians is associated with sleep-related problems and/or psychological stress. Methods: Eight hundred-thirty-one Finnish orchestra musicians completed a questionnaire that covered, among others, indicators of sleep-related problems, possible sleep bruxism, and stress. Results: In total, 488 questionnaires were completed. The single variable ordinal logistic regression models revealed at least moderate associations between frequency of sleep bruxism and female gender, shorter sleep duration, longer sleep latency, problems in sleeping during concert season, feeling more often tired during the daytime, restless legs, a poor self-rated sleep quality, and more stress experience. The variables that remained in the final model were sleep duration, gender, and stress. Conclusion: Musicians who sleep 7 hours or less per night report more sleep bruxism, as compared to those who sleep 8 hours or more. Female gender and high-stress experience were associated with more sleep bruxism. © 2020 The Author(s). Published with license by Taylor & Francis Group, LLC

Psychosocial factors associated with pain outcomes in patients with painful temporomandibular disorders and headaches

The objective of this study was to assess the association between psychosocial factors (in terms of anxiety, somatization, depression, and optimism) and pain (in terms of headache pain intensity and pain-related disability), in patients with a painful temporomandibular disorder (TMD) and one of the following headache types: migraine, tension-type headache (TTH), or headache attributed to TMD, corrected for the influence of bruxism. A retrospective study was conducted at an orofacial pain and dysfunction (OPD) clinic. Inclusion criteria were painful TMD, with migraine, TTH, and/or headache attributed to TMD. Linear regressions were performed to assess the influence of psychosocial variables on pain intensity and on pain-related disability, stratified per headache type. The regression models were corrected for bruxism and the presence of multiple headache types. A total of 323 patients (61% female; mean age 42.9, SD 14.4 years) were included. Headache pain intensity only had significant associations in TMD-pain patients with headache attributed to TMD, and anxiety showed the strongest relation (β = 0.353) with pain intensity. Pain-related disability was most strongly associated with depression in TMD-pain patients with TTH (β = 0.444), and with somatization in patients with headache attributed to TMD (β = 0.399). In conclusion, the influence of psychosocial factors on headache pain intensity and pain-related disability depends on the headache type presenting

Associations of reported bruxism with insomnia and insufficient sleep symptoms among media personnel with or without irregular shift work

<p>Abstract</p> <p>Background</p> <p>The aims were to investigate the prevalence of perceived sleep quality and insufficient sleep complaints, and to analyze whether self-reported bruxism was associated with perceptions of sleep, and awake consequences of disturbed sleep, while controlling confounding factors relative to poor sleep.</p> <p>Methods</p> <p>A standardized questionnaire was mailed to all employees of the Finnish Broadcasting Company with irregular shift work (n = 750) and to an equal number of randomly selected controls in the same company with regular eight-hour daytime work.</p> <p>Results</p> <p>The response rate in the irregular shift work group was 82.3% (56.6% men) and in the regular daytime work group 34.3% (46.7% men). Self-reported bruxism occurred frequently (often or continually) in 10.6% of all subjects. Altogether 16.8% reported difficulties initiating sleep (DIS), 43.6% disrupted sleep (DS), and 10.3% early morning awakenings (EMA). The corresponding figures for non-restorative sleep (NRS), tiredness, and sleep deprivation (SLD) were 36.2%, 26.1%, and 23.7%, respectively. According to logistic regression, female gender was a significant independent factor for all insomnia symptoms, and older age for DS and EMA. Frequent bruxism was significantly associated with DIS (p = 0.019) and DS (p = 0.021). Dissatisfaction with current work shift schedule and frequent bruxism were both significant independent factors for all variables describing insufficient sleep consequences.</p> <p>Conclusion</p> <p>Self-reported bruxism may indicate sleep problems and their adherent awake consequences in non-patient populations.</p

Time courses of myofascial temporomandibular disorder complaints during a 12-month follow-up period

AIMS: To investigate the time courses of myofascial temporomandibular disorder (TMD) pain and mandibular function impairment (MFI), and to identify predictive factors associated with these time courses. METHODS: During a 12-month period following conservative TMD treatment, the time courses of myofascial TMD pain and pain-related disabilities were assessed by questionnaires. Ninety-six myofascial TMD patients participated, of whom 70 completed the study. Before treatment (baseline data), Characteristic Pain Intensity (CPI), MFI, parafunctional activities, and psychological status were assessed, and at completion of treatment and at 3, 6, 9, and 12 months, CPI and MFI were scored again. Individual time courses in scores were analyzed using linear growth modeling. RESULTS: Baseline values of CPI had a positive correlation with CPI during follow-up (P = .002), whereas the influences of reported parafunctions and of pain elsewhere on CPI scores were close to significance (P = .058 and .06, respectively). Patients with a low somatization score showed a further decline in CPI during follow-up (P = .027), whereas patients with a high score showed a gradual increase (P = .030). Baseline values of MFI were positively correlated with MFI scores during the follow-up period (P = .000). The influence of reported parafunctions on MFI was not significant (P = .174), but that of pain elsewhere was (P = .004). The trend for a further decline in MFI values during follow-up was close to significance (P = .063) for patients with low somatization scores. Patients with high somatization scores showed a significant increase in MFI values (P = .007). CONCLUSION: Baseline reports of pain and impairment, oral parafunctional activities, pain elsewhere in the body, and somatization are associated with the severity and time course of myofascial TMD complaints following treatment

De behandeling van myogene CMD-pijn

Van diverse therapieën wordt beweerd dat zij effectief zijn in het verminderen van myogene pijn bij craniomandibulaire dysfunctie (CMD). Helaas bestaat er nog geen overzichtsartikel waarin de effectiviteit van al deze behandelvormen wordt gepresenteerd. Doel van dit artikel is om, door een systematisch literatuuronderzoek, gerichte adviezen voor de tandarts op te stellen voor de behandeling van myogene CMD-pijnpatiënten. De uitkomst van het literatuuronderzoek suggereert dat alle geselecteerde behandelvormen, inclusief placebobehandelingen, even effectief zijn in het verminderen van myogene CMD-pijn. Het verdient daarom aanbeveling om bij de therapiekeuze altijd terughoudend te zijn en dus gebruik te maken van reversibele behandelvormen. Tandarts en patiënt moeten echter wel rekening houden met de mogelijkheid dat pijnklachten na afbehandelen aanwezig kunnen blijven (zij het op een lager niveau), of na verloop van tijd weer kunnen terugkeren
