In 1999, our department was the first in the nation to establish a clinic dedicated to oral care for the elderly and other people requiring care. In that time we have developed an oral care system to provide effective oral care for the elderly and other people requiring care, which is easy on both them and their families, and an oral care support instrument for elderly requiring a high level of care. Using these methods and instruments, we have attempted to raise the QOL of both the dependent elderly and their caregivers, and improve the general health condition.
