A study of dentists' knowledge and beliefs regarding temporomandibular disorders in Korea.

The purpose of this study was to examine the knowledge and beliefs regarding TMD (temporomandibular disorders) held by practicing dentists in Seoul, the capital and largest city in Korea. Four aspects of TMD (psychophysiological, psychiatric disorders, chronic pain and pathophysiological) were examined. The results indicate that while the role of psychophysiologic factors in the etiology of TMD and the role of psychiatric disorders is relatively widely acknowledged in the practicing community, there is a high level of controversy regarding the pathophysiology of TMD and the appropriate diagnosis and treatment of these chronic conditions. The findings partially duplicate a similar survey of dentists in Seattle, Washington, and one survey done in Kansas in the United States.
