    Objective: The purpose of this study was to compare the anesthetic efficacy of lidocaine with epinephrine 1:80,000 and mepivacaine 2% with epinephrine 1:80,000, in the infraorbital nerve block. Methods: experimental study, 100 subjects randomly received infraorbital nerve block, by using 2% lidocaine with 1:80,000 epinephrine and 2% mepivacaine at two separate appointments spaced at least at 1 week apart, teeth were pulp tested, three consecutive times using the three levels of the pulp tester cycles for a total of 120 minutes. Success was defined as no response after to 2 consecutive readings with the electric pulp tester, students described the symptoms and the response generated, latency period and the action time of each patient was recorded. Results: latency was set in seconds, the anesthetic lidocaine showed a mean of 14.69 ± 7.5 SD and 14.88 ± 8.02 mepivacaine, there was no statistically significant differences between the two groups (P = 0.86), while the action time was determined in minutes for the lidocaine was 186.7 ± 54.54 SD and 146.7 ± 39.28 for mepivacaine, differences were statistically significant (P = 0.0000). Conclusions: anesthetic lidocaine is more effective since it has a longer action period and does not represent differences in latency, comparing with mepivacaine.
