TL;DR: The expert group defined bruxism as a repetitive jaw-muscle activity characterised by clenching or grinding of the teeth and/or by bracing or thrusting of the mandible and proposed a diagnostic grading system of 'possible', 'probable' and 'definite' sleep or awake bruXism.

TL;DR: The literature on the prevalence of different research diagnostic criteria for temporomandibular disorders (RDC/TMD) version 1.0 axis I diagnoses in patient and in the general populations was summarized and systematically reviewed.

TL;DR: Findings must be interpreted with caution due to the poor methodological quality of the reviewed literature and to potential diagnostic bias related with having to rely on an individual's self-reported bruxism diagnosis alone.

TL;DR: Wake clenching seems to be associated with psychosocial factors and a number of psychopathological symptoms, while there is no evidence to relate sleep bruxism with Psychosocial disorders.

TL;DR: A systematic review of the literature on the temporomandibular disorders (TMD)-bruxism relationship published from 1998 to 2008 was carried out in this paper, where a total of 46 articles were included for discussion in the review and grouped into questionnaire/self-report, clinical assessment, experimental, polysomnographic, and electromyographic studies.
