The tested aligner systems were Taglus Premium made of polyethylene terephthalate glycol (the TAG group) and CA\u00ae Prodin+ made of a transparent copolyester and a thermoplastic elastomer (the PRO group). A total of 56 samples were firstly divided into two groups according to the tested system\u2014TAG and PRO. Each group was subsequently divided in four subgroups according to immersion solution: A\u2014artificial saliva, B\u2014cola, C\u2014coffee, D\u2014red wine. Color measurements were performed on Days 1, 7 and 14 using a portable colorimeter and the CIE L*a*b* system. The obtained results showed significant color changes in both materials when exposed to coffee and red wine (p &gt; 0.05). Samples in the PRO group showed a greater susceptibility to discoloration (higher \u0394E values) when compared to the TAG group after submersion in cola (p = 0.025), coffee (p = 0.005) and red wine (p = 0.041) solutions. Statistical analysis revealed that all of the color parameters \u0394L*, \u0394a*, \u0394b* and \u0394E of both tested materials were affected by submersion in coffee solution for 14 days. In conclusion, the CA\u00ae Pro+ aligner system is more prone to staining compared to the Taglus material after submersion for 14 days in cola, coffee and red wine solutions. Submersion for 14 days in coffee solution alters all of the color parameters (\u0394L, \u0394a, \u0394b and \u0394E) of both tested aligner materials.<\/jats:p>","DOI":"10.3390\/ma17164009","type":"journal-article","created":{"date-parts":[[2024,8,12]],"date-time":"2024-08-12T11:23:46Z","timestamp":1723461826000},"page":"4009","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Color Stability of Various Orthodontic Clear Aligner Systems after Submersion in Different Staining Beverages"],"prefix":"10.3390","volume":"17","author":[{"given":"Nicolae Daniel","family":"Olteanu","sequence":"first","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, Faculty of Dental Medicine \u201cGrigore T.
