Brief summary

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.

Inclusion criteria

An individual must meet all of the following criteria to be eligible to participate in the study: * Be able to understand the informed consent. * Provide signed and dated informed consent form * Be able to understand all directions for data gathering instruments in English * Be willing and able to comply with all study procedures and be available for the duration of the study * Planning to undergo extraction of one or more partial or fully impacted mandibular 3rd molars * Be 18 years or older * Be in good general health as evidenced by medical history * Women must agree to use one of the following methods of contraception while participating in this study: * contraceptive pill * intra-uterine device * condoms * abstinence
