Articaine versus Lidocaine concentration in the palatal tissues after supra-periosteal buccal infiltration anesthesia

Palatal local anesthetic injection is a painful procedure. Previous studies have reported successful extraction of maxillary teeth using only buccal infiltration of 4% articaine without palatal anesthesia. The aim of the present study was to determine the levels of 4% articaine solution in the palatal bone and mucosal tissues after its buccal injection and compare it with 2% lidocaine solution in New Zealand white rabbits.
