Comparação da eficácia anestésica e capacidade de difusão da articaína a 4% e lidocaína a 2%, ambas com adrenalina 1:100.000, em cirurgias de terceiros molares superiores não-irrompidos

Abstract

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 (Articaine-DFL) and 2% lidocaine with epinephrine 1:100,000 (Alphacaine-DFL), in a double-blind crossover manner. Eighteen healthy volunteers, aged 14 to 26 years, with non-irrupted superior third molar removal indications were selected. All procedures were executed in the morning at once, by the same oral and maxillofacial surgeon. The diffusion ability and the efficacy of anesthetic solutions were verified by the 11-Point Box Scale, administered two times for each solution: after incision and detachment and after suture. The anxiety degree was evaluated by Corah Dental Anxiety Scale. Data were analyzed trough Wilcoxon´s test (α= 0.05). All the median values for the 11-Point Box Scale were similar. Besides that there were no significant statistical differences between articaine and lidocaine solutions after incision and detachment (p= 0.329) neither after the surgical procedures (p= 0.393). Results showed that in healthy patients, both anesthetic solutions had the same diffusion to palatal mucosa, and 2% lidocaine with epinephrine 1:100,000 and 4% articaine with epinephrine 1:100,000 presented similar clinical behavior, thus choosing either solution does not change the quality of the non-irrupted superior third molars removal.
