Dental Device Offers Sturdier Fillings

Wednesday, 21 Dec 2011 12:25 AM


A new, high-tech instrument called a plasma brush uses a “cool flame” based on chemical reactions to quickly create longer-lasting fillings, researchers say.

The plasma brush cleans out cavities for filling in about 30 seconds. Fillings made using the plasma brush are 60 percent stronger than fillings made without the brush, researchers say.

“There have been no side effects reported during the lab trials, and we expect the human trials to help us improve the prototype,” said Qingsong Yu, associate professor of mechanical and aerospace engineering at the University of Missouri.

The new device is also expected to reduce the cost of tooth restorations.

Human clinical trials are expected to begin in early 2012. If all goes as planned, and the U.S. Food and Drug Administration approves its use, the plasma brush may become available to dentists as early as the end of 2013, researchers say.
