Gloria;
It is my underdtanding that epinephrine increases the life of the
novicaine/lidocaine... so dentists prefer to do this. the alternative,
lidocaine without epinephrine can neccesitate injecting more often especially
for a long procedure.
As is often the situation the mother can request, if she knows to do so,
that the dentist not use epinephine.. She should be prepared for a degree of
static..
