Objective: To evaluate the mechanical properties of NiTi archwires subjected to different food solutions in an in vitro experiment.

Materials and Methods: A total of 550 NiTi archwires were stratified by diameter (5 levels), exposure solution (5 levels), and time point (3 levels), with 10 wires per combination . The wires were placed in Petri dishes, submerged in artificial saliva, and stored in an incubator at 37ºC. After 24 hours, they were daily exposed for 20 minutes to five different solutions: artificial saliva, milk, Coca-Cola^®, lemon juice, and coffee. Mechanical tests were performed at three time points: baseline (T0), day 15 (T15), and day 30 (T30). Force, tensions, and deformation results were compared among groups using a three-way ANOVA was used to test main effects and interactions, followed by one-way ANOVA with Tukey's post hoc for pairwise comparisons (T0 vs. T15; T0 vs. T30), with a significance level of 95% (p < 0,05).

Results: Most archwires not exposed to food solutions showed lower mean values of resistance (force test), tension, and deformation than archwires exposed to beverages at T15 and T30.

Conclusion: Daily exposure of NiTi orthodontic archwires to different beverages may induce changes in their mechanical properties of tension and deformation.
