Abstract
We experienced 3 cases of the oral surgical treatment of the Patients with Psychiatric dIso rders, and we present the summaries. Case NO. 1, a patient with depressive neurosis, and case NO. 2, a patient with schizophrenia, both revealed traumatic fracture of the lower jaw, which was considered to be caused by psychiatric disorders. Case NO. 3, a patient with alcohol-depending melancholy, was an example of tongue gangrene injured by self-biting. The patients didn't give consent to treatment directly by themselves, but the satisfactory results were obtained with understanding and cooperation of the psychiatrists in charge and their families. Besides, Case NO. 3 was a request of another psychic hospital, so the Patient had an ambulatory treatment with attendance of a male nurse, and improved. In any case, it was considered that we couldn't give oral surgical treatment without understanding and cooperation of the psychiatrist in charge.
