Anesthetic Efficacy of Liposomal Prilocaine in Maxillary Infiltration Anesthesia

February 22, 2010 updated by: University of Campinas, Brazil

Local Anesthetics New Formulations: From Development to Clinical Tests

This blinded randomized, crossover, three period study aim to evaluate the anesthetic efficacy of liposome-encapsulated 3% prilocaine compared to 3% plain prilocaine and 3% prilocaine with 0,03IU/mL felypressin, after 1.8mL infiltration in the buccal sulcus of the maxillary right canine, in 32 volunteers.
