| Résumé: | The objective of this study was to evaluate the possible changes in color of aesthetic elastic ligatures soaked in different solutions. Five different brands of aesthetic elastic ligatures were evaluated in the present study. Measurement of the discs´ color was performed using a reflectance spectrophotometer (UV-visible spectrophotometer, UV-2450, Shimadzu®, Kyoto, Japan). Subsequently, the discs were immersed in artificial saliva (AS) or three different solutions: red wine (RW) (Miolo Terranova® 2010, Casa Nova, Brazil), coffee (CF) (Café Três Corações®, RioGrande do Norte, Brazil) or Coca-Cola® (CC) (Coca-Cola®, Belo Horizonte, Brazil). It was determined that the tested solutions were able to cause color changes in the aesthetic elastic ligatures. The coffee solution caused the greatest color change in all of the brands of ligatures evaluated, followed by the red wine solution. In conclusion, OSE and GAC brands of aesthetic elastic ligatures displayed the best performance. |
