TI  - Color Stability of Preheated Novel Composite
Resins Immersed in Different Beverages: In Vitro Study
AB  - To examine the color stability of 3 preheated
composite resins immersed in different beverages for 1, 7, and 30 days.
Material and Methods: Ninety disc-shaped specimens were prepared,
30 specimens from each of three different restorative materials
[GrandioSO (GSO), GrandioSO x-tra (GSX), VisCalor bulk (VCB)],
using 8-mm diameter and 4-mm thickness molds. Each group was divided into 3 subgroups (n=10) to be immersed into beverages (red wine,
coffee, and distilled water). The color change values [CIEDE2000
(ΔE00)] were calculated at the end of the 1st, 7th, and 30th days. Generalized linear models and multiple comparison tests with Bonferroni correction at a significance level of p<0.05 were performed for the
comparisons of ΔE00 values. Results: Among all composite and immersion media combinations, at the end of 30 days, the most prominent color change values were observed in the GSX group immersed in
coffee and red wine and the VCB group immersed in red wine. For all
composite groups, the lowest color change values were measured after
immersion in distilled water in all evaluation periods. All composite
groups immersed in red wine showed the color change from the 1st day,
while those exposed to coffee from the 7th day, above the clinically acceptable values. Conclusion: The color change values of preheated
resin-based composites kept in coffee and red wine were affected by the
properties of the immersion solution and storage times rather than the
type of the material.
