Efficacy of analgesia promoted by lidocaine and articaine in third molar extraction surgery. A split-mouth, randomized, controlled trial.

It can be concluded that the use of 4% articaine associated with epinephrine (1:100,000) reduced the time of onset of analgesia and the necessity for anesthetic supplementation in third molar extraction surgeries compared to the use of 2% lidocaine associated with epinephrine (1:100,000).
