Phenazone versus placebo: effects on post-operative course

Area of Science:

• Oral Surgery
• Pharmacology
• Pain Management

Background:

• Impacted wisdom teeth removal often results in significant post-operative pain and swelling.
• Effective pain management is crucial for patient recovery and satisfaction after dental surgery.

Purpose of the Study:

• To evaluate the efficacy of phenazone in managing post-operative pain and swelling following impacted wisdom tooth extraction.
• To compare phenazone's effects against a placebo in a double-blind, crossover study.

Main Methods:

• A double-blind, crossover study involving 24 patients undergoing bilateral impacted wisdom tooth removal.
• Patients received either phenazone or placebo, with post-operative outcomes assessed objectively and subjectively.
• Assessments included swelling, local temperature, mouth-opening ability, pain scores, and patient preference.

Main Results:

• Phenazone significantly reduced post-operative pain compared to placebo, as indicated by fixed interval and visual analogue scales.
• Swelling was not significantly different between phenazone and placebo groups (82% of placebo levels).
• Phenazone showed a trend towards reduced local temperature increase and less impaired mouth-opening ability, but a slight increase in bleeding.

Conclusions:

• Phenazone offers significant pain relief in oral surgery, potentially superior to acetylsalicylic acid but not as effective as paracetamol.
• Patient preference favored phenazone despite a higher incidence of nausea, likely due to effective pain management.
