Abstract
We report a case of conversion disorder in which mother-child-related stress triggered the development of occlusal disharmony. A 49-year old housewife visited our hospital for treatment of occlusal disharmony. Her 21-year old daughter was exhibiting a coercion disorder. In the mother, the uneasiness caused by suppression of an unconscious inner conflict had transformed a conversion disorder into a somatic condition. Her emotional feelings of insecurity and impatience and unusual physical feeling in the mouth were the primary features. It is thought that the condition was identified and mitigated at an early stage. The patient consulted with both our department and that of psychiatry and has understood the stress correlation.
