Abstract
This study compared the efficacy and safety of single oral doses of 60 mg/kg and 90 mg/kg paracetamol in fit young adult patients undergoing third molar extractions. The study was a randomised, blinded, crossover design on 20 young, fit adults. Paracetamol was administered 30 minutes prior to the surgical extraction of the teeth, which was done under intravenous sedation and local anaesthesia. There were no clinically or statistically significant differences in the pain scores between 60 mg/kg or 90 mg/kg doses until the intake of rescue analgesics. There was a reduction in factor VII activity with 90 mg/kg dose compared to 60 mg/kg dose. It may be concluded that the 90 mg/kg dose, though safe, does not offer any advantages over 60 mg/kg dose of paracetamol in young fit adults undergoing third molar surgery.
