University of Missouri researchers have developed a new non-thermal plasma argon tool for extracting decayed material from cavities and killing bacteria (Jan. 20, 2012).

The device uses a stream of ionized particles to dislodge decayed pulp and sterilize the area. Researchers say that cleaning out the cavity with the new tool can take as little as 30 seconds, and create a surface which bonds better to filling material. Fillings applied after use of the new tool are 60% stronger and can last up to 10 years, the researchers say. Another advantage is that with no drill bit contacting the tooth, and no transferred vibration, patient pain is almost non-existent. Human clinical trials of the device are expected to begin at the University of Tennessee-Memphis early this year.

This is the starting wave of the future. I heard all this before using all sorts of impractical tools but this should be a low cost venture. I wonder if there will be stock?
