Introduction: Anesthetic solutions have their own characteristics regarding properties such as latency, potency, and duration of action. Many authors have demonstrated the superiority of diffusion of 4% articaine solutions, although there is controversy in the scientific literature about this discussion. Objective: The purpose of this study was to compare the ability to induce palatal mucosa anesthesia and the anesthetic efficacy after superior alveolar posterior nerve block of two anesthetic solutions: 4% articaine with epinephrine 1:100,000 and 2% lidocaine with epinephrine 1:100,000. Methods: This original experiment is a cross-sectional, double-blind, randomized study of eighteen healthy volunteers, aged 14 to 26 years, with impacted maxillary third molar ex- traction indications. The diffusion ability and the effica- cy of anesthetic solutions were verified by the 11-point Box Scale, and the anxiety degree was evaluated with the Corah Dental Anxiety Scale. Results: Results showed that in healthy patients, both anesthetic solutions had the same diffusion to palatal mucosa and, presented similar clinical behavior. Conclusion: Both tested solutions showed similar diffusion capacity and anesthetic efficacy, proving to be equally suitable for use in extraction of impacted maxillary third molars.
