Özet:

 Purpose: The aim of this study is to evaluate the effect of different polishing systems on the color stability of single-shade composite resin after coffee immersion, brushing cycles, and re-polishing. Materials  Methods: A total of 40 disc-shaped single-shade composite resin Omnichroma, Tokuyama, Japan specimens were prepared using a standard mold. One-step OneGloss, Shofu, USA, two-step Clearfil Twist Dia, Kuraray, Japan, multi-step OptiDisc, Kerr, USA polishing systems were applied to each group n10 in accordance with the manufacturers instructions. No polishing procedure was applied to the Control group. Representing 6 months and 1 year of clinical use, specimens were immersed in coffee solution 612 days and subjected to brushing cycles 500010000 cycles. The specimens were then re-polished by applying the same polishing procedures as initially applied. Color measurements were repeated in all periods, and color change values were calculated with the CIEDE2000 formulation. Kruskal-Wallis analysis was used for between group comparison, and the Mann-Whitney U test was used as a post-hoc test. Statistical significance was accepted as p0.05. Results: At 6 months and 1 year periods, the ΔE values of the control group and OneGloss group were statistically similar and significantly higher than the other groups p0.05. There was no statistically significant difference between all groups in ΔE values after re-polishing. Conclusion: Two-step and multi-step polishing systems exhibited superior properties in the color change of single-shade composite resin. Although re-polishing reduced the ΔE values, no polishing system was able to reduce the color change of single-shade composite resin below the acceptable threshold.
