ABSTRACT

Objectives : The purpose of the study is to investigate the xerostomia in the chronic severepsychiatric patients in Korea because there were few reports on xerostomia in the psychiatric patients. Methods : The subjects were 61 psychiatric patients in the mental hospital by conveniencecluster sampling. A self-reported symptom questionnaire was filled out by the three researcherson the basis of medical records by the informed consent. The stimulated salivary flow rate ofthe patients was measured by saliva sampling. Results : The subjects consisted of 45.9% of male and 54.1% of female. High school graduationaccounted for 40.0% and 20.0% did not attend the school. The majority of the patients weremedicaid recipients. Schizophrenia accounted for 86.9% and most patients were long term carerecipients. A total of 68.9% of the patients suffered from salivary dysfunction. The medicationin schizophrenia seemed to decrease the stimulated salivary flow rate and made the patients difficultin chewing and swallowing due to xerostomia and low saliva secretion(p<0.05). Conclusions : Medication in schizophrenic patients caused the salivary dysfunction. So thecollaboration between the psychiatry doctors and dental hygienists is very important to improvethe salivary secretion in the schizophrenic patients. The continuous and long term care of thexerostomia will help the patients maintain the good oral hygiene.
