Oral Hygiene in Patients With Severe Mental Illness: A Pilot Study on the Collaboration Between Oral Hygienists and Mental Health Nurses.

PURPOSE: To test (a) the effects of an educational intervention about oral hygiene on the knowledge of mental health nurses, and (b) the effects of an oral care intervention on oral health in patients with severe mental illness (SMI). DESIGN AND METHODS: We applied a pretest/posttest design to test improvements in nurses' knowledge and the oral health of SMI patients. FINDINGS: The nursing staff's knowledge increased significantly after the educational intervention. The oral health of the patients improved significantly after the oral health intervention. PRACTICE IMPLICATIONS: Oral health of SMI patients can improve significantly with basic oral health interventions carried out by collaborating oral hygienists and mental health nurses.
