REFINED NASA TECHNOLOGY MAY REPLACE DENTIST'S DRILL


In the near future, a laser device inspired by NASA may replace
the dentist's drill.  Flip a switch and it will also replace the
dentist's razor-sharp scalpel.  Best of all, it's virtually
painless and requires no anesthesia for most patients.  Lasers
exist today that work on hard tissue like teeth to prepare the
tooth for filling, and on soft tissue for gum treatment and oral
surgery.  But none do both, and buying two laser systems is
expensive.  That is one reason why only 5 percent of approximately
140,000 U.S. dentists use a laser system.  Now, researchers at
NASA's Langley Research Center, Hampton, VA, have demonstrated
that the two laser wavelengths important to dentists can be
produced from a single, easy-to-use system.
