Pain Relief with Combination Acetaminophen/Codeine or Ibuprofen following Third-Molar Extraction: A Systematic Review...

Area of Science:

• Dentistry
• Pharmacology
• Evidence-based Medicine

Background:

• Third molar extraction is a common dental procedure often associated with significant post-operative pain.
• Effective pain management is crucial for patient recovery and satisfaction following third molar surgery.

Purpose of the Study:

• To systematically review and meta-analyze randomized, blinded, placebo-controlled studies on pain management after third molar extraction.
• To compare the efficacy of a combination of acetaminophen (600 mg) with codeine (60 mg) versus ibuprofen (400 mg) for pain relief.

Main Methods:

• Searched PubMed and ClinicalTrials.gov for relevant studies using keywords: molar, tooth, extraction, pain.
• Included randomized, blinded, placebo-controlled studies evaluating single doses of acetaminophen/codeine or ibuprofen.
• Analyzed standardized pain relief (PR) at 6 hours and summed total pain relief over 6 hours (TOTPAR6).

Main Results:

• Ibuprofen (400 mg) demonstrated a large effect size (SMD 3.009 for TOTPAR6, 0.854 for PR at 6 hours) in reducing post-extraction pain.
• Acetaminophen (600 mg) with codeine (60 mg) showed a smaller effect size (SMD 0.796 for TOTPAR6, 0.0186 for PR at 6 hours).
• A standardized mean difference (SMD) of 0.8 or greater indicates a large effect.

Conclusions:

• Single-dose ibuprofen (400 mg) is an effective analgesic for managing pain after third molar extraction.
• Ibuprofen demonstrates superior efficacy compared to the combination of acetaminophen and codeine for post-third molar extraction pain.
• These findings support the use of ibuprofen as a primary analgesic option for this common surgical procedure.
