The purpose of this study was to investigate the differences between resident oral care policies provided by 2 types of long-term care (LTC) institutions. The study also investigated factors affecting LTC institutional caregivers' perceptions of the residents' oral health. Overall, 103 completed questionnaires were returned. Of these, 44 were from senior citizen welfare institutions, and 59 were from nursing homes. The variables affecting these perceptions included institution type and whether the residents attended hospital dental clinics or consulted a hospital doctor regarding oral health problems. The research results showed that institution type and whether an oral care-related professional was available in an institution were correlated with an increase in institutional caregivers' perceptions of oral care.
