Abstract
The term of psychosomatic disorder in dentistry implies a variety of medically unexplained, functional symptoms related to the orofacial region. While most of these symptoms may be closely related to somatization of mental illness such as depression, anxiety disorder and somatoform disorder, excessive and inappropriate dental treatments are likely to be given to psychosomatic patients in a dental clinic. In particular, oral cenestopathy (bizarre, unpleasant sensation in the oral cavity) is a refractory, chronic syndrome that may be attributed to a hallucinatory symptomatology of psychotic disorder. Dentists are required to be aware of somatization symptoms in the orofacial region and consider informed consent of patients lacking organic etiology in regard to risks of dental treatments and consultation to psychiatrists.
