[Local anesthesia with and without vasoconstrictors: indications, contra-indications and complications in relation to the health of the patient].
Patient's fear of pain is one of the major reasons of not routinely seeking dental care. Local anesthetics are commonly used in dentistry and dental practitioners must be familiar with the effects and side-effects of these substances in medically compromised patients. This article is a review of these side-effects and the resulting contraindications. A frequently asked question is when to combine a vasoconstrictor to a local anesthetics. The purpose would be to reduce the anxiety and avoid any pain during dental procedures. Indeed, pain produces much more endogenous epinephrine than the small amount of epinephrine combined to the local anesthetics.
