If anesthesia was not sufficient to proceed with the procedure, a rescue anesthesia would be used. Rescue anesthesia consists of an infiltration injection of lidocain hydrochloride 2% with epinephrine hydrochloride (1:100,000). In the control group, an intra-oral lidocaine-epinephrine injection will be applied due to treatment. Safety, efficacy and acceptance will be assessed in the same manner to what is performed in the experimental group.
