ABSTRACT
Abstract: Objectives: Respiratory infection is a major cause of death in the elderly.
We have evaluated the role of professional oral health care (POHC) by dental hygienists in reducing respiratory infections in elderly persons requiring nursing care.
Methods:
Two populations of elderly persons, one receiving POHC and one not, were examined to determine numbers of microorganisms, potent pathogens of respiratory infection, enzymatic activity in saliva, fevers, prevalence of fatal aspiration pneumonia and prevalence of influenza.
Results:
In the first population, we found a high prevalence of potent respiratory pathogens such as Staphylococcus species, Pseudomonas aeruginosa and Candida albicans.
Patients who received POHC showed a lower prevalence for these pathogens than those who did not.
The ratio of fatal aspiration pneumonia in POHC patients was significantly lower than that in patients without POHC (non-POHC) over a 24-month period (P
Conclusion:
These results suggest that POHC by dental hygienists is effective in preventing respiratory infections in elderly persons requiring nursing care.

Quote: : Hygiene first.
There was a lot of gargling going on in 1918, but Rice suspects that it did more harm than good.
But a study in Japan during a flu outbreak two years ago found that those who made a point of brushing their teeth and their tongue a few times a day reduced the flus severity.
It was compared with keeping a doorstep swept .

Reminds me, that gargling has a tradition in Japan.
however, Professional oral health care by dental hygienists
will not be available in a pandemic, so what can we do by ourselves ?
Doesn't this demonstrate, that flu transmits by eating ?
Even if it's killed in stomach, it may infect in mouth.
>
In the POHC group, ...
1 of 98 patients was diagnosed with influenza;
>
Whereas, in the non-POHC group, 9 of 92 patients were diagnosed with influenza.
suggesting >90% of flu-transmission were through the mouth !
That however makes me doubt the whole study
