Abstract
The present study aimed to compare latency and duration of inferior alveolar nerve block delivered by the carpule syringe or the Morpheus® computerized system. This study was a split-mouth, double-blind, randomized clinical trial with 31 volunteers. The inferior alveolar nerve block was performed with carpule syringe and Morpheus® device. The teeth had latency times and duration of anesthesia measured using the pulp electric tester. All data were tabulated and sent for statistical analysis with a level of significance set at 5%. The latency time were the same for most cases. The duration of the anesthetic effect was higher for the carpule technique. The success rate for the carpule technique was 80.65%. For the technique with Morpheus®, the percentage of success was 83.87%. There were no significant differences in pain after injection. Most of the volunteers preferred the anesthetic technique with Morpheus® (64.52%), while 35.48% preferred the carpule syringe. The techniques with carpule and Morpheus® presented same time of latency and anesthetic duration, as well as similar success rate. Pain experienced during the execution of the two techniques was the same. As for the preference for the injection devices, the majority opted for Morpheus® system.
