Abstract
For 30 years, we have cooperated with dentists and oral surgeons in the practice and research of liaison psychiatry. Liaison psychiatrists ask dentists to do the following in their clinical practice: 1. Dentists should not readily explain to patients that their somatic complaints are caused by psychogenesis, stress, or psychosomatic diseases; 2. Dentists should recognize that there are many differential diagnoses of systemic physical disorders in somatic complaints around the oral area without objective findings; 3. The rules of basic medical interviews should be followed; 4. Treatments should be performed after gaining informed consent; 5. Dentists should use psychotropic drugs very carefully; and 6. Choose the best psychiatrists when making referrals.
