Based on scientific evidence, what is the best method of post-operative pain management following surgical extractions?
For a surgical extraction (flap, bone removal) what do you usually prescribed? Leave us your comments. Has the new legislative requirements in Ontario on narcotic prescriptions changed your practice?
Pain management in dentistry is an important objective, necessary for patients’ comfort and trust. There are numerous medications and strategies which could be utilized for post-operative pain management following surgical extractions such as wisdom teeth extration.
In his review on combination analgesic therapy in dental pain, Mehlisch suggests that monotherapy (eg acetaminophen alone) in treatment of pain is limited due to the ceiling effect that may be encountered where additional drug does not provide additional analgesia, and due to increased potential for adverse effects. Combination therapy (eg acetaminophen with codeine) is more useful because pain is treated via different pathways, and because reduced doses of each individual drug can be used. He suggests that mild pain be treated with acetaminophen or a low-dose non-steroidal anti-inflammatory drug (NSAID); moderate pain with a higher dose NSAID or acetaminophen, Tramadol, or opioid with acetaminophen or NSAID; and severe pain with opioid or Tramadol, with acetaminophen or NSAID. Similarly, Phero et al suggest combining and optimizing an NSAID and acetaminophen together as baseline pain management, and adding opioid as needed for breakthrough pain.
Post-operative pain may also be influenced by factors other than post-operative analgesics. Timing of analgesic administration may be considered, as ketorolac provided before surgery, rather than afterwards, has been shown to increase the time of analgesia and decrease the need for rescue analgesics. Another study found that post-operative pain was reduced and fewer analgesics were taken when patients were given a post-operative injection of bupivacaine rather than lidocaine following periodontal surgery. Finally, simple compression of the surgical site, with or without ice, was shown to significantly decrease post-operative pain following third molar surgery.
Unfortunately, no “best” method of post-operative pain control has been identified in the literature. Instead, pain management, both strategic and pharmacologic, should be tailored to individual patients and the procedures they will undergo.

Post-operative pain after extractions is one of the most dreaded aspects of dentistry; so gaining adequate and sustainable control of it is critical to good patient care.
The management of this postoperative pain has been extensively studied with several non-steroidal anti-inflammatory drugs and narcotics. No single analgesic regimen has so far been developed to provide sufficient pain relief without any side effect. To avoid the dose related side effects of narcotics, use of NSAIDS has become popular for mild to moderate postoperative pain.
In an Evidence-Based Study of the Literature for a comparison of frequently prescribed analgesics at the university of Toronto for postoperative pain following dental surgery, Moore et al. found acetaminophen with codeine (T#3) to be an effective analgesic when compared to placebo in postoperative pain. 1 out of 6 patients with moderate to severe pain will get at least 50% pain relief with one Tablet of T#3, while with 2 Tablets of T#3 1 out of 4 patients achieve at least 50% pain relief, The addition of codeine however, was accompanied by a significant increase in drowsiness and dizziness.
Ahmad et al. found that non-opioids, such as acetaminophen and NSAIDs, provided better pain relief, while all NSAIDs as a group (ie. aspirin, ibuprofen, ketorolac, naproxen, ibuprofen) were not statistically better at relieving pain than the acetaminophen codeine combination, NSAIDs prescribed in specific doses after dental surgery, such as ibuprofen 400mg and ketorolac10mg, were found to be significantly more effective at relieving pain than acetaminophen 600mg in combination with codeine 60mg. Similarly, a dose of 10mg of ketorolac was more efficacious than Tylenol 3.
Cooper et al. investigated the efficacy and safety of various doses of oxycodone in combination with acetaminophen, combining peripherally acting acetaminophen and centrally acting oxycodone are effective analgesics. Oxycodone 5mg with acetaminophen (Percocet) proved to be an effective analgesic for treating moderate to severe postoperative pain with the least unwanted side effects. It was determined that Percocet is the most effective analgesic, followed by the NSAIDs ibuprofen and ketorolac , and then Tylenol #3 .
Merry et al, also found that patients using the combination of acetaminophen and ibuprofen experienced less pain during the first 48 h after oral surgery than those using the same daily dosage of either agent alone. In summary, there are many combinations of narcotic and non-narcotic regimens that can be effective. Titrate the drug and dose to the patient and surgical needs with the knowledge that no single rule is effective for everyone or every situation. Having several options in mind is the most effective way to get early and long-lasting pain control for your patients.
