Eficacia de la anestesia pulpar mediante el bloqueo de los alveolares superiores medio y anterior

Abstract

Many dental procedures in the maxilla require local anesthesia, one of theme is endodontic treatment. Anterior Middle Superior Alveolar nerve block (AMSA), that anesthetize from central incisor to second premolar. The purpose of this study was to determine the AMSA pulpar anesthetic efficacy as well as the latency period, anesthesia time and the pain to injection and infiltration. Fifty patients were chosen for this study; all of them were anesthetized with the AMSA technique in one side of the maxilla using a conventional syringe with 1,8 ml of lidocaine 2% with 1:80000 epinephrine. The anesthetic efficacy was 68% for the second premolar, 66% for the first premolar, 64% for the canine, 88% for the lateral incisor and 72% for the central incisor. Concluding that the AMSA technique is effective in the pulpar anesthesia and can be used as complementary anesthesia to the infiltrative and block anesthesia in the maxilla
