Abstract
The aim of the present study was to assess effect of 4% articaine infiltration
versus 2% lidocaine nerve block after premedication by ibuprofen on anesthetic
efficacy in endodontic treatment of first permanent molar with acute
irreversible pulpitis in a randomized single blind control trial. The Null
hyposthesis was that there would be no difference in anesthetic efficacy of 4%
articaine and 2% lidocaine after premedication with ibuprofen.
