Enhanced anti-influenza virus activity of saliva following toothbrushing.

ABSTRACT:

Objective

Influenza, a respiratory infection caused by the influenza virus, has been associated with good oral hygiene, which correlates with a reduced incidence of the disease. Saliva possesses inherent antiviral properties against the influenza virus. However, the relationship between toothbrushing, a common oral hygiene practice, and the antiviral activity of saliva remains poorly understood. This study aimed to evaluate the effect of toothbrushing on the anti-influenza virus activity of saliva.

Materials and methods

Sixteen adults without oral disease participated in this open-label, single-arm study. Resting saliva and mouth-rinsed water samples were collected before toothbrushing. Participants then brushed their teeth with a toothbrush and toothpaste for five minutes,
