RT Journal Article T1 Effect of time-dependent ibuprofen administration on the post operatory after impacted third molar extraction: a cross-over randomized controlled trial A1 Pérez González, Fabián A1 Abusamak, Mohammad A1 Sáez Alcaide, Luis Miguel A1 Torres García Denche, Jesús A1 Marino, Faleh Ahmad Tamimi AB Purpose: To evaluate time-dependent administration of ibuprofen in a lower third molar extraction model. Methods: Eleven patients requiring bilateral surgical removal of lower third molars were recruited and randomized into a blinded crossover randomized controlled trial. For 3 days after surgery, the control group was prescribed ibuprofen 400 mg every 8 h. On the other hand, the experimental group received also ibuprofen 400 mg at breakfast and lunch, replacing the dinner intake with a placebo. Pain measurements (Visual Analog Scale from 0 to 10) were recorded at baseline, 24, 48, and 72 h postoperatively. Facial swelling and trismus were also measured at baseline, 24, and 72 h postoperatively.Results: Postoperative swelling and pain perception did not show signifcative diference between the control and experimental groups at 24, 48, and 72 h. Trismus was signifcantly lower in the control group than in the experimental group at 72 h postoperatively (p=0.008). Rescue medication consumption seemed to be comparable between groups. Conclusion: Eliminating night time ibuprofen might be insignifcant for pain control after third molar extraction.
