“…The causes of TMD can therefore be described as multifactorial, including an association with SB [9,14]. It is important to note, however, that the association with SB has been a matter of controversy [42] for a long time.…”

“…In addition, most of these studies were initially conducted for mechanistic reasons. It is interesting to note that although some of these studies identified an association between TMD and SB [11,12], others made no such connections [13][14][15]. These differences could be explained by heterogeneous study methodology and/ or the use of different clinical examination procedures to assess the presence of MP.…”

“…This might explain the conflicting results of PSG studies, because SB may fluctuate over the course of a few nights, especially for infrequent grinders [16,17]. It has been shown that the sole use of questionnaires, anamnestic information, or clinical examination is not sufficiently reliable [10,14]. One approach used to overcome these problems is to supplement anamnestic and clinical examination with the use of electromyographic (EMG) devices, which assess muscle activity during sleep [18].…”

Prevalence and potential factors associated with probable sleep or awake bruxism and dentin hypersensitivity in undergraduate students ResumoObjetivo: Mensurar a prevalência de provável bruxismo do sono e em vigília e de hiperestesia dentinária cervical de estudantes universitários e verificar os sintomas a eles associados. Metodologia: Este é um estudo transversal, cujo diagnóstico de provável bruxismo foi realizado pelo relato dos estudantes em ranger e/ou apertar os dentes durante o sono e em vigília combinado com o diagnóstico clínico de desgaste dentário e dor da musculatura do masseter à palpação. O diagnóstico de hipersensibilidade dentinária cervical foi realizado por testes de sensibilidade ao toque com sonda exploradora e a jato de ar da seringa tríplice. A amostra consistiu de 306 universitários entre 19 a 35 anos. Os dados foram armazenados e analisados no programa SPSS v.15.0 for Windows. Resultado: A prevalência de provável bruxismo foi de 34,3%, não havendo predominância entre os gêneros. O provável bruxismo em vigília foi o mais predominante (61,9%), ocorrendo principalmente quando o indivíduo estava em estado de concentração (63,1%). Não houve uma associação entre provável bruxismo do sono e em vigília e hiperestesia dentinária (p=0,195). Os indivíduos com provável bruxismo do sono possuíram maior chance de acordar com dor nos músculos da face (OR=14,14, IC95% 5,06-39,55) e com provável bruxismo em vigília maior chance de cansaço muscular facial ao mastigar ou falar por muito tempo (OR=2,88, IC95% 1,53-5,43) e dor nos músculos da face ao acordar (OR=5,31, IC95% 1,93-14,62). Conclusão: A prevalência de provável bruxismo foi 34,3% e de HDC 57,8%, com 22,2% destes também apresentando provável bruxismo, mas sem associação estatística. Indivíduos com provável bruxismo tendem a ter maior risco de apresentar dores faciais ao acordar e cansaço muscular facial ao falar e mastigar por muito tempo. Não houve associação entre provável bruxismo do sono e em vigília e hipersensibilidade dentinária cervical.Descritores: Bruxismo; sensibilidade da dentina; prevalência; análise multivariada. AbstractObjective: To measure the prevalence of probable sleep or awake bruxism and cervical dentin hypersensitivity of undergraduate students and to determine the symptoms associated with these conditions. Methodology: This was a cross-sectional study. A diagnosis of probable bruxism was reached when students reported clenching or grinding of the teeth during sleep and/or wakefulness, and when they also presented some of the signs and symptoms of bruxism and masseter muscle pain on palpation. Cervical dentinal hypersensitivity was diagnosed by testing for sensitivity to pain in the cervical region of the teeth. Pain was triggered either by touch (using a #5 probe) or by an air jet spray. The sample consisted of 306 university students aged between 19 and 35 years old. The data were stored and analysed using SPSS software, version 15.0 for Windows. Result: The prevalence of probable bruxism was 34.3%, with no predominance r...

“…Thus, it is no surprise that those using the tautological ASDA definition to test a relation between SB the behaviour and facial pain (21) or between SB and tooth wear (22) occasionally find an association between SB and those health outcomes. It is actually startling to acknowledge that, given the definition with which the PSG-based RDC/SB is intended to maximise correspondence, only one study found an association between TMD status and RDC/SB (23), which was not apparent in an earlier subsample (24) and which found such high rates of SB in both case (63%) and control (33%) samples that either standards for SB or overall sample selection (or both) raise serious questions about research design. In contrast, multiple other studies have failed to find a relation between RDC/SB-diagnosed SB and TMD pain (3, 20, 25–27).…”

Summary Inspired by the international consensus on defining and grading of bruxism (Lobbezoo F, Ahlberg J, Glaros AG, Kato T, Koyano K, Lavigne GJ et al. J Oral Rehabil. 2013;40:2), this commentary examines its contribution and underlying assumptions for defining sleep bruxism (SB). The consensus’ parsimonious redefinition of bruxism as a behaviour is an advance, but we explore an implied question: might SB be more than behaviour? Behaviours do not inherently require clinical treatment, making the consensus-proposed ‘diagnostic grading system’ inappropriate. However, diagnostic grading might be useful, if SB were considered a disorder. Therefore, to fully appreciate the contribution of the consensus statement, we first consider standards and evidence for determining whether SB is a disorder characterised by harmful dysfunction or a risk factor increasing probability of a disorder. Second, the strengths and weaknesses of the consensus statement’s proposed ‘diagnostic grading system’ are examined. The strongest evidence-to-date does not support SB as disorder as implied by ‘diagnosis’. Behaviour alone is not diagnosed; disorders are. Considered even as a grading system of behaviour, the proposed system is weakened by poor sensitivity of self-report for direct polysomnographic (PSG)-classified SB and poor associations between clinical judgments of SB and portable PSG; reliance on dichotomised reports; and failure to consider SB behaviour on a continuum, measurable and definable through valid behavioural observation. To date, evidence for validity of self-report or clinician report in placing SB behaviour on a continuum is lacking, raising concerns about their potential utility in any bruxism behavioural grading system, and handicapping future study of whether SB may be a useful risk factor for, or itself a disorder requiring treatment.
