The oral hygiene performance test: development and validation of dental dexterity scale for the elderly

This paper describes a test which was developed for use in assessing the functional oral hygiene status of an elderly population. The instrument was tested among 80 community-dwelling elderly subjects 65 or more years old. The instrument, the Oral Hygiene Performance Test [OHPT], is a direct-observation measure which objectively quantifies the individual's ability to perform oral hygiene and thus reduces subjective evaluation. The test utilized several items from other already-validated instruments currently in use in geriatric medicine to assess functional abilities in a geriatric population. Additional items were developed by the research team and were included in this 17-item test. The OHPT was validated with common measures of physical function and direct-observation measures. Construct validity was assessed by comparison of the OHPT scores with other commonly used measures of other dimensions. The instrument proved to be reliable and demonstrated construct as well as concurrent validity. It appears that the OHPT can prove useful to clinicians in assessing the oral physical function of elderly patients with regard to their maintenance of oral hygiene. Because the OHPT is a direct-observation instrument, it can even elicit higher functions in elderly patients. While effective among the studied population, the instrument may still need to be validated among more diverse populations, such as various ethnic groups and demented or severely impaired populations.
