Endodontic access was begun 7 min after the solution deposition. The success was defined as "no pain (0 mm)" or "weak/mild pain (0 mm and ≤54 mm)" during access opening, and during the first file insertion till working length.The compiled data of the number of failed cases were analyzed by two sample proportion test and of mean pain scores were analyzed by Student's unpairedThe efficacy of 4% articaine with 1:100,000 epinephrine has been found to be better than 2% lidocaine with 1:80,000 epinephrine, as only 0.8 ml of 4% articaine with 1:100,000 epinephrine was effectively used as compared to 1.6 ml of 2% lidocaine with 1:80,000 epinephrine.
