[Color stability of acrylic teeth immersed in a pigmenting solution].
Objective: The objective of this study was to compare the color stability of acrylic teeth immersed in a pigmenting solution.
Methods: An experimental in vitro study was carried out in 40 acrylic teeth from two commercial companies which were immersed in coffee and distilled water (control). The teeth were divided into 4 groups of 10 teeth each: Group-1 (Duratone-n® teeth immersed in distilled water), Group-2 (Duratone- n® immersed in coffee), Group-3 (Ivostar® teeth immersed in distilled water) and Group-4 (Ivostar® teeth immersed in coffee). The specimens were immersed in the respective solutions for 10 minutes a day for a period of 14 days. Finally, the samples were stored in an incubator at a constant temperature of 37 ° C. The color was recorded at two time-points (baseline time and at 14 days) using the Vita Easyshade® V spectrophotometer. The results were analyzed using the Stata 14 program.
Results: Ivostar® teeth immersed in coffee (2.24) and distilled water (2.88) showest the highest ∆E values compared to Duratone-n® teeth immersed in coffee (1.53) and distilled water (1.60).
Conclusion: After exposure to coffee, the Duratone-n® brand teeth presented greater color stability compared to those of the Ivostar® brand.
