Mouth Odor on Preventing Pneumonia by Oral Frailty

This research plan aims to first collect data on the oral function and oral hygiene status of the elderly population in the community and to understand the normal model of oral frailty among the older adults in the community. Subsequently, a comparison will be made between the oral status of hospitalized patients and the community-dwelling elderly population. The goal is to verify whether oral odor can be used as an objective biological indicator following intervention.
