The aim of this study is to assess Intraoperative pain for restorative treatment of Maxillary First Permanent Molars using Artinibsa Versus Artpharma in children during infiltration technique.

Local anesthesia is very important during dental procedure because it's a temporary loss of sensation which will lead to decrease the pain. Local anesthesia started with discovery of Cocaine in 1860. Followed by developments of Novocaine 1904 and lignocaine in 1942 by Lofgren. It became the gold standard drug compared to other local anesthetic. Later, several new drugs were discovered such as:Bupivacaine, Articaine, Mepivicaine etc. Articaine Hydrochloride (HCL) was available in Germany since 1976. It's the only amide local anesthesia containing ester group in its molecular structure leading to metabolizing of the drug by both plasma esterases and liver microsomal enzymes, the clinical efficacy and advantages of articaine is the duration of its anesthetic effect and its superior diffusion through the bony tissue.
