The objective of this study was to determine the latency time of 2% lidocaine and 2% mepivacaine using the direct trunk technique in patients treated at the Norbert Wiener University Dental Clinic in 2018. This research was descriptive, observational, non-experimental, prospective, cross-sectional, and comparative. The non-probabilistic sample consisted of 13 patients for each group, lidocaine 2% and mepivacaine 2%, using the direct trunk technique according to Lorenz Arranz, applying an anesthesia cartridge with a long needle (27G), reaching 20-25mm in 15 seconds, applied by a dentist. The time control was performed with a stopwatch, waiting for the tingling or numbness of the lip, tongue, and tooth, according to the administered sector. The data collection instrument was validated by expert judgment. The data were processed using SPSS version 23, applying the Student's t-test. For comparing categorical variables, independent two-sample tests were used, working at a 5% significance level (α = 0.05). The results showed that 2% lidocaine had an average latency time of 3.36 minutes, while 2% mepivacaine had an average latency time of 3.63 minutes. This study concluded that there is no significant difference between the latency time of 2% lidocaine and 2% mepivacaine.
