Abstract

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 thestaining solutions, the amount of stain varied based on their constituents and filler characteristics ©This work is licensed under Creative Commons Attribution 4.0 International License
