Efficacy of serratiopeptidase after impacted third molar surgery: a randomized controlled clinical trial

BACKGROUND: Serratiopeptidase has been clinically used in controlling surgical and non-surgical inflammatory conditions. This study was conducted to assess the therapeutic effect of Serratiopeptidase in patients undergoing surgical removal of impacted mandibular third molar. METHODS: This randomized clinical trial investigated the efficacy of Serratiopeptidase and Paracetamol after surgical removal of impacted third molar for 5 days (n = 67) as compared with an equivalent dose of placebo and Paracetamol (n = 66). Outcome measures were reported pain, trismus and swelling using Laskin method. All outcome measures were recorded on days 0, 1, 2, 4, and 5 post-surgeries. RESULTS: In this clinical trail 133 patients (mean age 23 years, 54% female) completed the study. Baseline characteristics were comparable across treatment groups. Serratiopeptidase significantly improved trismus compared with control on the 4(th) day (27.30 ± 7.3 mm and 32.06 ± 7.7 mm, respectively (P < 0.001) Swelling markedly improved, The distance from the lower edge of the earlobe to the midpoint of the symphysis for cases vs control were 111.49 ± 8.1 mm and 115.39 ± 9.9 mm, respectively (P < 0.001). Reported pain, showed no statistical significance difference. CONCLUSION: Serratiopeptidase resulted in better inflammation improvement than placebo over 5 days. Further studies are warranted to assess longer-term and clinical outcomes, as well as safety. CLINICAL RELEVANCE: Serratiopeptidase administered postoperatively helps in improving trismus and swelling after removal of impacted lower third molars.
