Methods: Totally, 130 specimens (n = 10) were prepared from four different 3D-printed resin composites (Brilliant Print Experimental, Crowntec, Temp PRINT, VarseoSmile Crown Plus), six subtractive CAD/CAM materials (Initial Lisi Block, IPS e.max CAD, Katana Avencia, Telio CAD, Tetric CAD, Vita Enamic) and three direct light-curing resin composites (Clearfil Majesty ES-2 Classic, Tetric EvoCeram, and G-ænial Universal Injectable), and immersed in five solutions (water, tea, red wine, coffee and curry) for 28 days. Initial and final color values (CIE L* a* b*) were measured using a spectrophotometer over white and black backgrounds. Color changes were calculated (ΔE00) and statistically compared using two-way repeated measures analysis of variance and Fisher's post-hoc test (α = 0.05). Results: Statistical analysis of ∆E00 values revealed that two 3D-printed resin composites exhibited comparable discoloration to two subtractive CAD/CAM resin composites and one of the lithium disilicate over a black background. They revealed less discoloration compared with all direct resin composites (p < 0.05). Significance: The investigated commercially-available 3D-printed resin composites are reliable to use in visible restorations, where common subtractive CAD/CAM and direct resin composites are indicated. 3D-print CAD/CAM Color stability Dental material Discoloration Resin composite Dewey 617.6 205 Division de cariologie et d'endodontie 24P1 false 189 Groupe Krejci Ivo (médecine dentaire) 240 Dental materials 7e1f0514-256e-4986-971f-90a53c927438 Article (Published version) Restricted 10678.pdf 2636113 application/pdf 4216fcdee2c50bbfdd1f7b28284f3de1e8417cd8968d040d09588ab8e2d44f8c restrictedAccess Faculté de médecine / Section de médecine dentaire / Département de médecine dentaire préventive et de premier recours / Division de cariologie et d'endodontie
