Objective: Color of natural teeth changes after orthodontic treatment. The aim of the study was to evaluate color changes of enamel before and after fixed mechanotherapy and compare the effects of different staining agents on enamel discoloration. Materials and Methods: Hundred freshly extracted premolars were divided into four groups of n= 25 each. Baseline color measurements were taken before bonding through reflectance spectrophotometer(X-Rite i1Pro). Postbonding samples were suspended in test solutions; Group1(control group) samples stored in distilled water and Group2, 3, and 4 in tea, coffee, and turmeric solutions, respectively for a week. The samples were then debonded and cleaned with eight fluted tungsten carbide bur followed by pumicing. Color evaluations were made in accordance with Commission Internationale de l'Eclairage L* a* b color system. ΔE values were compared for samples before and after debonding. Results: Mean ΔE difference value was found maximum for Group3(mean 12.4560, standard deviation[SD] 4.7207) and minimum for Group1(mean 9.7120 SD 4.2009). One-way ANOVA was used for intergroup comparison with P <0.05. No statistical significance was found in the ΔE difference values in between the groups. Conclusion: Orthodontic bonding and debonding procedures have an effect on enamel discoloration clinically, although various stains used in the study had no statistical significant difference among themselves.
