A good anesthesia is essential in dental surgical procedures. Success is not always achieved, especially when it comes to the inferior alveolar nerve block, which due to the large anatomical variations has a high failure rate. The aim of this study was to evaluate the anesthetic failure rates of the inferior alveolar nerve with pterigomandibular technique in lower third molar extraction procedures. 67 healthy patients of both sexes between 18 and 35 years were selected from the Discipline of Surgery of Araçatuba Dental School - UNESP, requiring third molars extraction. The anesthetic technique used was the pterigomandibular block with hydrochloride of mepivacaine 2 % with epinephrine 1: 100,000 (Mepivalem Dentsply, Cantanduva, SP, Brasil) in maximum standardized amount of three tubes (5.4 ml) for each surgery, which were performed by the same operator. After checking the sensation of anesthesia in the areas anesthetized by the inferior alveolar nerve, the surgical procedures began. Painful symptoms were record during surgeries. 117 surgical procedures were performed, (114 exodontias and 3 coronectomy). During the surgical procedures 4 patients reported pain during maneuvers of odontesection, representing 3.41% of anesthetic failure. The techniques used to treat anesthetic failure were anesthesia milohioideo nerve, intraligamentaria and intrapulpal
