text: After many studies with varying number of subjects it has been found that that the blood pressure of the patients of the group without vasoconstrictor are significantly worse, in terms of control of the pain and stress, than those of the group with vasoconstrictor when the subjects were injected with local anaesthesia without and with vasoconstrictors respectively prior to tooth extraction(1).It is attributed to the bad anaesthesia obtained due to using local anesthesia without a vasoconstrictor which led to more stress during the extraction of teeth leading to increase in the endogenous catecholamines.
