Resumo
Os autores mostram neste experimento que ao lado do trabalho técnico, o dentista não deve desprezar os conhecimentos de ordem sistêmica, que, em certas ocasiões, assumem importante papel na interpretação e definição dos fenômenos que possam aparecer durante os procedimentos odontológicos.

Abstract
The authors studied clinical changes in 20 patients with normal blood pressure. After injection of an anesthetic solution with nor-epinephrine in two different volumes of 1.8 ml and 7.2 ml respectively. There were no alterations in the arterial blood pressure of the patients while they were in the waiting room or in the operating room. An injection of 1.8 ml or 7.2 ml of anesthetic solution altered the arterial blood pressure. The application of four infiltrated injections (7.2 ml), due to the actual act of injection, caused a liberation of endogenous adrenaline which consequently raised the blood pressure.
