A double-blind, randomized study of naproxen sodium, ibuprofen, and placebo in postoperative dental pain.

In a double-blind, parallel, placebo-controlled study, 203 patients with post-operative dental pain following the extraction of one or two bony impacted third molars were randomized to receive a single dose of naproxen sodium 220 mg, ibuprofen 200 mg or placebo. Pain intensity and pain relief were assessed at intervals for 12 hours postdose. Both active drugs demonstrated superior analgesic efficacy over placebo. Naproxen sodium and ibuprofen were comparable both in onset of analgesic action and in pain relief. From 1 to 12 hours postdose, naproxen sodium showed a trend for superior analgesic efficacy compared with ibuprofen; this trend reached statistical significance at the 12-hour time point. Both drugs were well-tolerated and effective analgesics for postoperative dental pain.
