Narrator: This is Science Today. Imagine doing away with cavities by simply rinsing with a mouthwash every month or so? Well, this may soon be a reality, thanks to antimicrobial technology developed by UCLA microbiologists. Dr. Wenyuan Shi explains that after a decade of work, they've recently shown in clinical trial that subjects who rinsed just one time with their experimental mouthwash experienced a nearly complete elimination of the bacteria that's the main cause of tooth decay and cavities.
Shi: We're still trying to find out through the current clinical trial how long it takes, but we know this is not going to be a daily application. It's going to be monthly.
Narrator: Once on the market, this will be the first anti-dental caries drug since fluoride almost 60 years ago.
Shi: This is going to be one more preventive tool that's going to be very useful for the general public. Especially kids — essentially we'll be able to prevent them from getting tooth decay and we're very excited about that.
