Population-based and non-patients studies of TMD, published in the English language, prior to June 2005 were included. Well defined guidelines for conducting a meta-analysis for observational studies (MOOSE) were followed. Electronic databases (MEDLINE, CINAHL, SCI-E, and EMBASE) were searched (n=645). Reference lists of relevant articles were screened, and the journals “Orofacial pain” and “Oral Rehabilitation” were hand searched (n=31) for the years 1996 to 5/2005.
