High blood pressure is always a contraindication to the use of vasoconstrictors in dentistry
A) True
B) False
B
Explanation: B) Avoiding vasoconstrictors based on their impact on blood pressure alone may be misguided. Use of a local anesthetic drug without a vasoconstrictor may not provide profound or durable anesthesia. The lack of profound anesthesia can result in unmanageable pain, which, in turn, can lead to a spike in blood pressure due to the release of endogenous epinephrine in response to the pain. This endogenous release may be greater than administered doses of epinephrine.
