Clinical efficacy of 0.75% ropivacaine vs. 2% lignocaine hydrochloride with adrenaline (1:80,000) in patients undergoing removal of bilateral maxillary third molars: a randomized controlled trial.

Background: Lignocaine with adrenaline is routinely used as a local anesthetic for dental procedures. Adrenaline was added to increase the duration of anesthesia. However, epinephrine containing a local anesthetic solution is not recommended in conditions such as advanced cardiovascular diseases and hyperthyroidism.
