Articaine hydrochloride (HCL) is a hybrid molecule classified as an amide local anesthetic (LA) agent. But it possesses both amide and ester characteristics, so the biotransformation occurs in plasma and liver. In this study, we have evaluated the diffusion property for palatal anesthesia effect after buccal infiltration of articaine for extraction of maxillary molar tooth comparing it with lignocaine which requires a separate palatal injection. A randomized prospective study was conducted involving 40 patients divided into 4 groups (Group A, B, C, D). Each group was sub-divided into sub-group I and II with 5 patients each. All the patients in sub-group I were administered with 2% lignocaine HCL and patients in sub-group II with 4% articaine HCL. All the patients who received 2% lignocaine HCL required palatal injection along with the buccal injection. Patients who received 4% articaine required palatal injection for extraction of firm tooth whereas the extraction of mobile tooth did not require the additional palatal injection. But the onset of action was longer in group that received articaine. From this study we conclude that articaine has diffusion properties and can be used as a modality for extraction of mobile maxillary tooth without the need for a separate palatal injection.
