What are the benefits of epinephrine in dentistry?
Epinephrine is a vasoconstrictor commonly added to local anesthetics. Its purpose is to increase the duration of the anesthetic by slowing down the systemic metabolism of the anesthetic.

What hormone causes vasodilation of the blood vessels?
Epinephrine can cause vasodilation provided the level is low enough. If beta-2 recptors are activated (without the level of epinephrine being high enough to involve the significant numbers of alpha receptors), then the effect of epinephrine on the vascular smooth muscle be relaxation, thus, dilation. However, higher levels of epinephrine will activate alpha receptors which will cause vasoconstriction.
What is the effect of combining TCAs and biogenicamines?
