The objective of this study was to evaluate the efficacy of cognitive behavioral therapy intervention for patients who experienced pain during orthodontic treatment. The baseline characteristics were assessed via questionnaires and oral examinations. Four hundred and fifty eligible individuals were recruited and randomized by computer-generated block randomization into three groups: cognitive behavioral therapy intervention (n = 150), ibuprofen intervention (n = 150), and no intervention (control; n = 150). Primary outcomes were the change from baseline in pain intensity measured with 100-mm Visual Analog Scale (VAS) scores at 1, 2, 3, 7, 14, and 30 days after initial archwire placement. Outcomes assessment was blinded and followed the intention-to-treat principle. One hundred forty-three (95.30%), 145 (96.70%), and 141 (94.00%) individuals in the cognitive behavioral therapy, the ibuprofen, and the control groups, respectively, completed the one-month follow-up evaluations. Those in the cognitive behavioral therapy group showed a greater decrease in mean VAS scores than did those in the control group over the previous five time-points (p < 0.001). Cognitive behavioral therapy was shown to be effective in pain control during the initial stage of orthodontic treatment. The study registration number was ChiCTR-TRC-00000556.
