Materials and Methods: A total of 120 disc-shaped specimens (n = 10 per group) were prepared from the two composites and immersed for 12 days in distilled water (control), orange juice, green detox, red detox, pomegranate juice, or multivitamin water. Color coordinates (L*, a*, b*) were measured with a spectrophotometer at baseline and after immersion, and \u0394L*, \u0394a*, \u0394b*, and \u0394E were calculated using the CIELAB system. Data were analyzed using two-way ANOVA with Games-Howell and Welch\u2019s t-tests (\u03b1 = 0.05). Results: Material, immersion solution, and their interaction significantly affected all color parameters (p &lt; 0.001). FB showed significantly higher \u0394E than FU across all six solutions, including distilled water (p = 0.014). In FB, orange juice produced the highest color change (\u0394E = 17.33 \u00b1 1.61), followed by pomegranate juice (14.01 \u00b1 0.33) and red detox (10.08 \u00b1 0.72); in FU, \u0394E ranged from 1.76 \u00b1 0.76 (distilled water) to 5.16 \u00b1 2.08 (orange juice). Orange juice caused a pronounced increase in lightness in FB (\u0394L* = 16.12 \u00b1 1.37), unlike the darkening produced by the other beverages. All beverage groups in both materials exceeded the acceptability threshold (\u0394E = 2.7), whereas the distilled water controls of both materials remained below it. Conclusions: The bulk-fill composite was significantly more susceptible to discoloration than the nanofilled composite for all beverages. Health-oriented drinks, particularly orange, pomegranate, and red detox juices, produced clinically unacceptable color changes that should be considered in esthetic treatment and dietary counseling.<\/jats:p>","DOI":"10.3390\/ma19173637","type":"journal-article","created":{"date-parts":[[2026,8,27]],"date-time":"2026-08-27T08:02:27Z","timestamp":1787817747000},"page":"3637","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Color Stability of Conventional and Bulk-Fill Resin Composites in Health-Oriented Beverages"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3793-4512","authenticated-orcid":false,"given":"Zeynep Hale","family":"Keles","sequence":"first","affiliation":[{"name":"Department of Restorative Dentistry, Faculty of Dentistry, Istanbul Atlas University, 34408 Istanbul, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7127-109X","authenticated-orcid":false,"given":"Gorkem","family":"Sengez","sequence":"additional","affiliation":[{"name":"Private Practice, 34000 Istanbul, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8444-1780","authenticated-orcid":false,"given":"Aliye Tugce","family":"Gurcan","sequence":"additional","affiliation":[{"name":"Department of Pediatric Dentistry, Faculty of Dentistry, Dokuz Eylul University, 35340 Izmir, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1272-5581","authenticated-orcid":false,"given":"Soner","family":"Sismanoglu","sequence":"additional","affiliation":[{"name":"Department of Restorative Dentistry, Faculty of Dentistry, Istanbul University-Cerrahpasa, 34098 Istanbul, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,27]]},"reference":[{"key":"ref_1","first-page":"284","article-title":"Evaluation of stain susceptibility of different CAD\/CAM blocks after immersion in coffee","volume":"11","year":"2021","journal-title":"J.
