Since hell froze over. No seriously...it can be cold around the winter months...I personally haven't had freezing but my assistants are always complaining about freezing. I have never used freezing on teeth...I have used endo ice which is used to check tooth vitality.

Just a couple of questions up, several people answered that procaine was invented in 1905, so I guess that means about 100 years. It was NOT widely used, though, until the 1940's or 1950's. Modern chemicals replaced procaine in the late 1950's and early 1960's and a lot more dentists started to use it on a routine basis then.

I don´t have that, you mean liquid Nitrogen? I´ve heard a friend use it to numb soft tissue before injecting the xilocaine... but is not practical, he uses it because his brother is a dermathologist and work in the same office.
