A new study out from Germany indicates that bacteria-killing
jets of plasma could soon replace the dental drills currently
used to remove the cavities in our teeth making visits to the
dentist’s office less painful. Plasma is the fourth state of
matter, after solids, liquids and gases. It is formed when gases
are energized to the point where electrons fly off some or all
of their atoms. Researchers recently demonstrated that a small,
blowtorch-like device emitting a relatively cool beam of purple
plasma can eliminate oral bacteria in cavities, leaving more
tooth structure intact than a drill does. Get ready for this.
The first dentist to market himself as a mad scientist wins.
