OBJECTIVE: The objective of the present study was to investigate the pain on injection of articaine with adrenaline, prilocaine with phenylpressin , and lidocaine with adrenaline. STUDY DESIGN: The study sample was comprised of 497 consecutively seen patients received 497 maxillary buccal infiltration injections or inferior alveolar block injections of 4% articaine with 1:200.000 adrenaline, 3% prilocaine with 1.08 mcg phenylpressin, or 2% lidocaine with 1:100.000 adrenaline. Immediately after the injection, patients were asked to rate their injection pain on a six-point scale. RESULTS: There were no significant differences among the anesthetic solutions for injection pain. Patients usually reported mild or no injection pain for all of anesthetic administrations. CONCLUSION: Under the conditions of this study that lidocaine with adrenaline, articaine with adrenaline and prilocaine with phenylpressin seemed to be similar for pain on injection and they could be quite painless.
