Clinical Trial Summary

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.


Description:

The first stage will aim to examine the relationships between the level of oral frailty and pneumonia-associated pathogens, as well as to establish a mouth odor database among community-dwelling people; The second stage will compare the differences of the level of oral frailty, pneumonia associated pathogens, and mouth odor between 144 middle-aged and older healthy people and 160 hospitalization patients. The third stage will confirm whether the mouth odor is an effective biological maker to show the changes of oral frailty, pneumonia-associated pathogens, and mouth odor after oral management rehabilitation.

Intervention

Procedure:
Oral exercises and oral hygiene
The patients will be required to perform oral exercises and maintain oral hygiene twice a day. The investigators will assess their oral frailty, oral bacteria, oral odor, and other related clinical care data on the following time points: day 1 of hospitalization, day 3 of hospitalization, the day of discharge, one week after discharge, and one month after discharge.

Outcome

Type Measure Description Time frame Safety issue
Primary Clearance of pneumonia associated oral bacteria The investigators collected tongue specimens from participants for bacterial isolation and identification. The participants' specimens were collected using an eswab and sent for bacterial culture within 2 hours. Bacterial colonies were quantified (CFU/ml). To observe the variation caused by the number of bacteria, measurements were taken again after the intervention. The investigators assessed the clearance of bacteria based on the baseline.

Primary oral frailty measures (oral functions) The investigators measured seven items for patients to identify oral frailty including 1) the number of teeth, 2) masticatory ability, 3) difficulty making the "ta" sound, 4) tongue pressure, 5) abnormal swallowing pressure, and 6) tongue coating index (TCI), 7) oral dryness. Oral frailty was determined into three groups: non-oral frailty, 0 points; pre-oral frailty, 1-2 points; and oral frailty, = 3 points. The first day of admission (baseline)
