Randomized split-mouth study for evaluating the efficacy of nimesulide and nimesulide + Thiocolchicoside combination following impacted mandibular third molar surgery.

Background and Aim: This study aimed to evaluate acute postoperative pain management and trismus in 35 patients undergoing extractions of the two mandibular third molars, in mesioangular positions, at two different visits who consumed nimesulide + thiocolchicoside or only nimesulide. Material and Methods: According to the medication given, the patients were divided into two groups. Following the first surgery of the impacted third molar patients were given nimesulide (100 mg) + thiocolchicoside (8 mg) together. The healing period was waited for 15 days and in the poursuite of the second surgery, only nimesulide (100 mg) was administered every 12 hours for 7 days. Visual analog scales (VAS) were used to assess the pain in the 6th, 8th, 12th, 24th, and 48th hours and on the 3rd, 5th, and 7th days postoperatively. Digital calipers were used to measure (in mm) the mouth opening capacity pre and postoperatively on the 2nd and 7th days, respectively. Results: Regarding pain alleviation, the nimesulide + thiocolchicoside group was more effective than the nimesulide group. The VAS levels of nimesulide + thiocolchicoside at the 6th, 8th, 12th, 24th, and 48th hours and on the 3rd and 5th days were significantly lower than the nimesulide group. The mouth opening was observed higher in the nimesulide + thiocolchicoside group than in the nimesulide group (P > 0.05). In the nimesulide group, at the end of the 7th day, the trismus measurements were less than the preoperative measurements. There was no statistically significant difference in the Nimesulide + Thiocolchicoside group in the preop-7th days. Conclusion: Nimesulide (100 mg) + thiocolchicoside (8 mg) combination has higher analgesic efficacy and better trismus outcomes compared to only nimesulide (100 mg) when orally administered following mandibular third molar surgeries.
