Objectives: Aim of this study is to compare the color stability and surface roughness of four different color-adjustment composites produced using smart chromatic technology and a highly esthetic nano-hybrid composite after brushing with whitening toothpaste.
Materials and Methods: 4 different color adjustment composites and 1 nano hybrid composite are divided into 5 main groups according to their contents. A total of 120 disc-shaped specimens (8 x 2 mm) were prepared, 24 in each group. The prepared samples were sequentially kept in solutions (tea, coffee and cherry juice) for 12 days and randomly divided into 3 subgroups (n=8). Subgroup 1, brushing with distilled water; Subgroup 2, brushing with whitening toothpaste; Subgroup 3, home bleaching agent were applied (14 days). Color measurements were made with a spectrophotometer, ΔE values were calculated using the CIELAB formula. Surface roughness values were made using a profilometer device. Samples from each group were selected for SEM surface analysis.
Results: Among the composite groups, the highest coloration was observed in the Omnichroma, while the lowest ΔE values were observed in the Vittra composite group. Although the ΔE values on the 14th day were higher than the 7th day in all groups, the differences between them were statistically insignificant(p>0.05) In all composite groups (except Omnichroma), the ΔE values of brushing with whitening toothpaste at the end of the 14th day were higher than brushing with distilled water(p<0.05).
Conclusions: Although the application of home bleaching agent was found to be more effective in a short time in whitening color-adjustment composites; brushing with whitening toothpaste at the end of the 14th day was found to be as effective as the application of home bleaching agent. Coloring and bleaching procedures applied to color-adjustment restorative materials did not have a significant negative effect on surface roughness values.
