A new dentistry machine made in 2011 used to kill bacteria in the mouth. This machine shoots pulses of UV waves killing the bacteria. 3 foot machine, with xenon gas which is harmless is inside this machinery. It helps cleans thousands of peoples' rooms all around the hospitals. No people have yet died, so everyone has cleaner mouths, healthier mouths. Xenon is produced Brian Cruver in 11/02/11
"Brian Cruver, founder of Xenex, in Austin, Tex., aims to stomp the killers in their tracks. His weapon: a rolling, 3-foot-tall machine (think R2-D2 from Star Wars) called the Xenex that bathes hospital rooms with intense, millisecond pulses of ultraviolet light from a high-wattage strobe light. The UV penetrates bacteria and either scrambles their DNA, preventing reproduction, or kills them outright. Xenex also has motion sensors that shut it off in case someone opens a door; 30 minutes of that UV exposure would cause mild sunburn."
