Objectives
Narrative objectives1
The main cause of aspiration pneumonia is aspiration of saliva-containing bacteria, and the risk of developing the disease increases with the number of bacteria aspirated. Therefore, oral management centered on brushing is widely practiced to reduce the number of bacteria in saliva, but brushing causes plaque to fall into the mouth, which significantly increases the number of bacteria in saliva during brushing. Therefore, brushing methods using water, moisturizing gel, povidone-iodine-containing mouthwash, and povidone-iodine-containing gel are investigated for patients at high risk of aspiration pneumonia, to investigate brushing methods that do not increase the number of bacteria in saliva.
