Topical application of povidone iodine reduced the number of oral bacteria for at least 3 h after oral care in patients undergoing mechanical ventilation, and did not promote the growth of bacteria resistant to antibiotics or fungi. This is a simple and safe method to reduce oral bacteria for a longer time in Japan—similar to 0.12% chlorhexidine globally.
