Trial Summary

What is the purpose of this trial?The goal is to provide health care professionals, including dentists, with the best possible evidence for clinical decision making when deciding upon analgesics for acute post-surgical pain management, a double-blind, stratified randomized clinical trial will be conducted to test the hypothesis that a combination of over-the-counter non-opioid containing analgesics is at least as, if not more, effective (non-inferior) than the most commonly prescribed opioid analgesic. The impacted 3rd molar extraction model will be used due to the predictable severity of the post-operative pain and generalizability of results. This double-blind, prospective, stratified, randomized pragmatic clinical trial will use the impacted 3rd molar extraction pain model.
