Subjective sleep quality and temporomandibular disorders: Systematic literature review and meta-analysis.

Study Objectives: To assess the general subjective sleep quality in individuals with and without TMD, and its distribution among the TMD diagnostic groups.

Methods: A systematic review search was performed in Pubmed/MEDLINE, Embase, LILACS, Web of Science, SciELO, CINAHL and Cochrane Central as well as in the grey literature. Observational studies published since 1992 which used either the DC/TMD or RDC/TMD for TMD diagnosis and either the PSQI, SAQ or ESS questionnaires for sleep assessment were included.
