UCLA-Developed Mouthwash A "Smart Bomb" Against Cavities?
It's one of the most common conditions affecting over nearly half of children in the United States but now a mouthwash concocted by a UCLA microbiologist may render cavities and tooth decay a thing of the past.
The innovation developed by Wenyuan Shi, chairman of the UCLA School of Dentistry's oral biology section, acts as a sort of "smart bomb" against harmful bacteria like, S. mutans, a main cause of cavities and tooth decay.
"With this new antimicrobial technology, we have the prospect of actually wiping out tooth decay in our lifetime," he said.
A successful clinical study involving a dozen people found that those who rinsed with the UCLA-developed mouthwash just once over a four-day testing period experienced a near-complete elimination of the S. mutans bacteria.
There is a long path from Press Release to Product and it will be interesting to see if the bacteria will form a resistance. Still -- has the potential to be very very cool...
