Materials and Methods: The sample consisted of esthetic orthodontic elastomeric ligatures in the colors pearl, pearl blue, pearl white and colorless, which were immersed for 72 hours in five different solutions: distilled water (control group), coffee, tea, Coca-Cola ® and wine. The color changes of the esthetic orthodontic elastomeric ligatures were measured with the aid of a spectrophotometer, at T1 - as provided by the manufacturer; and T2 - after colorings process. Results: The results indicated that the esthetic orthodontic elastomeric ligatures of all initial hues are susceptible to pigmentation. Among the evaluated colors, all changed the finished look and the color of the samples tested. In ascending order, the color of the samples was as follows: distilled water, Coca-Cola®, black tea, wine and coffee. Conclusion: The substances that have a greater potential for pigmentation in esthetic orthodontic elastomeric ligatures were black tea, wine and coffee, respectively. All shades of esthetic orthodontic elastomeric ligatures are susceptible to color change. 09 30 2016 516 521 TODENTJ-10-516 1 10.2174/crossmark_policy opendentistryjournal.com benthamopen.com true Peer Reviewed Single blind Checked with iThenticate 2014-12-31 2016-6-4 2016-07-30 2016-09-30 https://creativecommons.org/licenses/by/4.0/legalcode 10.2174/1874210601610010516 1553506650 https://opendentistryjournal.com/VOLUME/10/PAGE/516/ https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-516/TODENTJ-10-516.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-516/TODENTJ-10-516.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-516/TODENTJ-10-516.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-516/TODENTJ-10-516.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-516/TODENTJ-10-516.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-516/TODENTJ-10-516.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-516/TODENTJ-10-516.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-516/TODENTJ-10-516.xml J.
