Human clinical trials are underway on the "plasma brush" a device that should revolutionize the dental industry with painless cavity filling:
In less than 30 seconds, the plasma brush uses chemical reactions to disinfect and clean out cavities for fillings. In addition to the bacteria-killing properties, the “cool flame” from the plasma brush forms a better bond for cavity fillings. The chemical reactions involved with the plasma brush actually change the surface of the tooth, which allows for a strong and robust bonding with the filling material.
“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 of MU, and Meng Chen, chief scientist from Nanova, Inc., which holds a co-patent for the plasma brush with MU.
For those of you who cringe at even the sound of a dentist's drill, this should be good news.
