| Research Abstract |
The aim of this study is to scientifically evaluate the effects of oral health care by using several objective indices such as salivary flow, salivary components and autonomic nervous activities. Through the 3 months'intervention of oral health education program for the community-dwelling elderly with xerostomia, unstimulated salivary flow and bitter taste sensitivity was significantly improved and cumulative time of repetitive saliva swallowing test was significantly shortened, showing that the program may be effective for improvement of oral function. Oral care of the elderly in nursing care by a dental hygienist for 3 months resulted in improvements of oral hygiene status as well as oral function such as salivation and taste. In addition, professional oral care caused significant decrease in salivary amylase activity and augmentation of parasympathetic nervous activity, objectively suggesting a reduction of stress and an enhancement of relax feeling which was consistent with improvement of subjective mood.
