Summary
Colored orthodontic elastics like white, pink, and gray can discolor over time due to diet. White elastics showed the most discoloration, while gray showed the least, with effects peaking around two weeks.
Area of Science:
- Orthodontics
- Biomaterials Science
- Esthetic Dentistry
Background:
- Discoloration of colored elastomeric modules is a significant concern in esthetic orthodontics.
- Patient satisfaction and treatment outcomes can be affected by the esthetic appearance of orthodontic appliances.
Purpose of the Study:
- To evaluate the in vivo discoloration of stretched colored elastomeric modules (white, gray, pink).
- To understand the impact of dietary factors on the color stability of orthodontic elastics.
Main Methods:
- Ninety elastomeric modules (30 each of white, gray, pink) were placed in patients' mouths for 1, 2, and 4 weeks.
- Color changes were measured using digital imaging and the Commission Internationale de l'Eclairage (CIE) L*a*b* color space.
- Statistical analysis included Analysis of Variance (ANOVA) and Least Significant Difference (LSD) tests.
Main Results:
- White elastomeric modules exhibited the highest degree of discoloration, followed by pink, then gray.
- Discoloration increased gradually over time, influenced by patient diet, with a peak effect around 2 weeks for white and gray modules.
- Pink modules showed discoloration that plateaued after 1 week.
Conclusions:
- Colored elastomeric modules discolor to varying extents over time.
- Patients should be informed about potential discoloration of elastics due to food and drink consumption.
- The findings highlight the importance of material selection and patient counseling regarding esthetic orthodontic treatment.
