Preoperative 15 mg of melatonin for surgical discomfort, pain, edema and trismus in mandibular third molar surgery: a randomized double-blind placebo-controlled clinical trial
摘要
This study aimed to evaluate the efficacy of a single preoperative 15 mg sublingual dose of melatonin in reducing surgical discomfort, pain, edema, and trismus following mandibular third molar extraction.
Materials and methodsA randomized, double-blind, placebo-controlled trial was conducted with 46 patients allocated to receive melatonin (n = 22) or placebo (n = 24) 45 min before surgery. The primary outcomes were intraoperative pain and discomfort and postoperative pain. Secondary outcomes included patient-perceived edema (VAS-Edema, days 1–5), trismus (5-point scale, days 1–5; interincisal measurement, day 7), and rescue medication consumption.
ResultsNo statistically significant differences were observed between the melatonin and placebo groups for any outcome. Intraoperative discomfort (QCirDental total score, p = 0.54) and pain (VAS, p = 0.67) were comparable. Similarly, postoperative pain levels across all time points (p = 0.67), edema over five days (p = 0.26), and trismus based on self-assessment (all days p > 0.50) and clinical measurement (p = 0.79) did not differ.
ConclusionWithin the limitations of this clinical trial, a single 15 mg preoperative dose of sublingual melatonin was not superior to placebo in alleviating surgical discomfort, pain, edema, or trismus after third molar extraction.
Clinical relevanceClinically, these findings suggest that melatonin may have limited effectiveness in managing common complications in oral surgery.
