ReviewRelationship between bruxism and temporomandibular disorders: a systematic review of literature from 1998 to 2008.
The present paper aims to systematically review the literature on the temporomandibular disorders (TMD)-bruxism relationship published from 1998 to 2008. ⋯ Investigations based on self-report or clinical bruxism diagnosis showed a positive association with TMD pain, but they are characterized by some potential bias and confounders at the diagnostic level (eg, pain as a criterion for bruxism diagnosis). Studies based on more quantitative and specific methods to diagnose bruxism showed much lower association with TMD symptoms. Anterior tooth wear was not found to be a major risk factor for TMD. Experimental sustained jaw clenching may provoke acute muscle tenderness, but it is not analogous to myogenous TMD pain, so such studies may not help clarify the clinical relationship between bruxism and TMD.
