I always found it fascinating how wars and conflicts have lead to
increadible advances in medicine.

Cyanoacrylates are very commonly used now in periodontal procedures.  Any
comments?  A little history from Wikipedia:

The use of cyanoacrylate glues in medicine was considered fairly early on.
Eastman Kodak and Ethicon began studying whether the glues could be used to
hold human tissue together after surgery. In 1964, Eastman submitted an
application to use cyanoacrylate glues to seal wounds to the United States
Food and Drug Administration (FDA). Soon afterward Dr. Harry Coover's glue
did find use in Vietnam — reportedly in 1966, cyanoacrylates were tested
on-site by a specially trained surgical team, with impressive results. In an
interview with Dr. Coover by the Kingsport Times-News, Coover said that the
compound demonstrated an excellent capacity to stop bleeding, and during the
Vietnam War, he developed disposable cyanoacrylate sprays for use in the
battlefield.

     “ If somebody had a chest wound or open wound that was bleeding, the
biggest problem they had was stopping the bleeding so they could get the
patient back to the hospital. And the consequence was — many of them bled to
death. So the medics used the spray, stopped the bleeding, and were able to
get the wounded back to the base hospital. And many, many lives were
saved. ”
