Epinephrine The inclusion of epinephrine in a dental office emergency kit is mandatory for the treatment of cardiac arrest and overwhelming anaphylaxis. However, it must be emphasized that these extreme conditions are the only situations that would require its use in the dental office emergency.
GCD- In mathematics, the greatest common divisor (gcd), also known as the greatest common factor (gcf), or highest common factor (hcf), of two or more non-zero integers, is the largest positive integer that divides the numbers without a remainder.
G-Code is the language used to control CNC machines. It's one type of CNC programming that CNC programmers use, the other type being CAM programming. Your machine's CNC controller probably executes g-code, although there are other possibilities--Heidenhain, Mazak, and others have proprietary formats. Some machines with proprietary formats can also run g-code.
