THE EVALUATION OF RESEARCH DIAGNOSTIC CRITERIA / TEMPOROMANDIRULAR DISORDERS (RDCITMD) FOR DIAGNOSIS OF TEMPOROMANDIBULAR DISORDERS

The main problem for diagnosis of temporomandihular disorders is the lack of standardized diagnostic criteria for defining clinical subtypes of temporomandihular disorders. A set of research diagnostic criteria for temporomandihular disorders (RDC/TMD) offered to allow standardization and replication of research into the most common forms of muscle and joint related TMD. The RDC/TMD are based on the earlier systems but draw their strength from the data gathered during a longitudinal epidemialogie study. The first axis is the sign and physical symptoms of TMD, the second axis is phychosocial factors that are associated with TMD. Many authors have studied the reliability and validity of RDC/TMD since 1992.Inthis arcticle the studies on the clinical utility. validity and reliability of RDC/TMD were evaluated.
