title: Double-blind, randomized, placebo-controlled trial comparing rofecoxib with dexketoprofen trometamol in surgical dentistry.
abstract: BACKGROUND
  Rofecoxib, a selective cyclooxygenase-2 inhibitor, and dexketoprofen trometamol, a single isomer non-steroidal anti-inflammatory drug (NSAID), are available for the treatment of acute pain. Both are claimed to have fewer adverse effects than traditional NSAIDs. We have compared them in a clinical setting.
  
  
  METHODS
  We performed a double-blind randomized controlled trial involving 120 patients undergoing surgical removal of a single mandibular third molar at the Edinburgh Dental Institute. Those who developed moderate pain within 4 h of the procedure were allocated to one of three groups: rofecoxib 50 mg (Group RO, n=37); dexketoprofen trometamol 25 mg (Group DE, n=42); or placebo (Group PL, n=41). Participants monitored pain intensity and pain relief for 24 h using visual analogue scales (VAS) and verbal rating scales (VRS). The summed, time-weighted pain relief score to 8 h derived from the VRS (TOTPAR 8) was used as the primary outcome variable.
  
  
  RESULTS
  No significant difference was demonstrated between Groups RO and DE using TOTPAR 8 as the primary outcome variable. Both drugs were significantly different compared with placebo. Rescue analgesia during the trial period was required by only 15 out of 37 subjects in Group RO, but 35 out of 42 subjects in Group DE. The median times to use of rescue medication were 150 (Group PL), 398 (Group DE) and 1440 min (Group RO). Both drugs were well tolerated and adverse events reported were mild to moderate in severity.
  
  
  CONCLUSIONS
  Rofecoxib and dexketoprofen trometamol are effective treatments for acute pain using a dental pain model and are well tolerated. Rofecoxib has a longer duration of action as a single dose and gave adequate analgesia for over half of that study group; patients in the dexketoprofen trometamol group needed more rescue analgesia.
