Dental care and oral hygiene are often neglected in nursing homes. This study examines the effect of an education program on the ability of nursing staff to conduct an oral health assessment for a population of persons with Alzheimer's disease and related disorders. The findings of this study showed that the CNA's are as capable as the Licensed Nurses in assessing oral health status. In future training of nursing staff, increased emphasis on identification of problems in specific areas may improve the overall assessments by nurses and nursing assistants.
