Comparison of the Effects of Nano Micelles Curcumin and Ibuprofen on Pain Reduction After Initial Arch Wire Placement: A Double-Blind Randomized Clinical Trial Study

Abstract

Aim: To compare the effect of nano micelles curcumin and ibuprofen on pain reduction after primary arch wire placement in orthodontic patients. Materials and Methods: In this double-blind randomized clinical trial study, 60 female patients between the ages of 14 and 30 years who had moderate tooth crowding and were candidates for fixed orthodontic treatment were examined. The subjects were divided into four groups (n = 15) of nano micelles curcumin (SinaCurcumin), ibuprofen, placebo of SinaCurcumin, and placebo of ibuprofen. Each patient received a questionnaire and a rectangular, flexible cube of silicone to record the severity of their pain under each of the three situations (biting posterior teeth together, fitting anterior teeth together, and without fitting the teeth together) at the designated time points (2 h, 6 h, bedtime, the second, third, and seventh days after archwire placement). The obtained outcomes were statistically verified and analyzed by the employment of SPSS Statistics Version 22. Results: despite the lack of any significant differences among the four groups in terms of pain severity upon biting by the anterior teeth 2 h after the intervention, there was a considerable difference in the cases of 6 h, bedtime, and the second, third, and seventh days subsequent of the placement of archwire. Our data indicated a lower rate of pain severity for SinaCurcumin group than the placebo of SinaCurcumin and ibuprofen groups at 6 h after the archwire placement. However, the pain severity of SinaCurcumin group at bedtime was significantly lower than ibuprofen group, which also resulted in a notably lower rate than the other groups at the second, third, and seventh days after the placement of archwire. Conclusion: These findings support the effectiveness of curcumin in reducing the pain severity of orthodontic patients. Nevertheless, it is a necessity to conduct further confirmation trials on this latter.
