Objectives: The purpose of this study was to evaluate the color stability of polished composite resin material with different filler technologies. Materials and Methods: Three composites were studied; Filtek™ Z350 XT (3M, ESPE, St. Paul, USA) [FXT] that has nano-cluster filler particles, Brilliant EverGlow™ (Coltene/Whaledent® AG, Altstatten, Switzerland) [BEG] which consists of submicron barium glass fillers and pre-polymerized fillers and Ceram.X® Sphere TEC™ (Dentsply, Konstanz, Germany) [CXS] with advanced granulated filler technology composite. Twenty standardized composite discs were prepared with each composite resin, and it was polished with Sof-Lex disks (3M, ESPE, St. Paul, USA). The baseline color was then recorded using a spectrophotometer (X-Rite PANTONE® iPro-2, Michigan). Eight samples from each group were then subdivided and immersed into freshly prepared solutions of turmeric, coffee, and four samples into distilled water for a total period of 3 hours/day for 30 days. Following this, the color was again recorded. The change in color (ΔE) was calculated, and the data obtained were subjected to Kruskal Wallis and Mann Whitney test. Results: A significant difference was seen between the staining characteristics of CXS and FXT. The mean color change in the values was highest in Ceram.X that was clinically unacceptable (ΔE>3.3). Conclusions: Though all composites revealed color changes after their immersion into the staining solutions, the amount of stain varied based on their constituents and filler characteristics
