Dental pain is largely inflammatory, and evidence-based medicine has shown that nonsteroidal anti-inflammatory drugs are the best analgesics for dental pain. The aim of this study was to compare the analgesic, anti-inflammatory and anti-trismus effect of a single dose of diclofenac and meloxicam after mandibular third molar extraction. Material and Methods: A total of 36 patients were randomized into two treatment groups, each with 18 patients, using a series of random numbers: Group A, was administered 100 mg of diclofenac; and Group B, 15 mg of mel- oxicam. Drugs were administered orally 1 hour prior to surgery. We evaluated pain intensity, analgesic consump- tion, swelling, as well as trismus. Results: The results of this study showed that patients receiving 15 mg of meloxicam had less postoperative pain (P=0.04) and better aperture than those receiving 100 mg of diclofenac (P=0.03). The meloxicam group presented less swelling than diclofenac group; however, significant statistical differences were not observed. Conclusions: Data of this double-blind, randomized, parallel-group clinical trial demonstrated that patients re- ceiving 15 mg of preoperative meloxicam had a better postoperative analgesia and anti-trismus effect compared with who were given 100 mg of diclofenac after third molar extractions. Key words: Diclofenac, meloxicam, dental pain, trismus, third molar surgery. e127 Med Oral Patol Oral Cir Bucal. 2016 Jan 1;21 (1):e127-34.
