Simple tooth brushing before surgery may stop pneumonia

This study tests whether a quick oral hygiene routine—brushing teeth and tongue, then rinsing with an antiseptic mouthwash—right before surgery can reduce the amount of bacteria that travel from the mouth into the windpipe during intubation. The trial involves 60 adults aged 60 or older having elective surgery under general anesthesia. Half will do the oral cleaning; the other half will receive standard care. Researchers will measure bacteria levels in the mouth and windpipe to see if the cleaning helps.
