Effect of Bleaching and Re-polishing Procedures on Stain Removal from Nanofilled Resin Composite
Keywords:coffee, resin composite, stain removal, tooth bleaching reagents
Background: Discoloration of resin composite restorations is attributed to a variety of reasons, which includes stained color that transfer from beverages such as tea and coffee. Various methods of stain removal on resin composite have been used to maintain the original color of restorations. Objective: To compare the efficacy of various finishing and polishing systems; in-office bleaching; home bleaching for stain removal on nanofilled resin composite. Method: The simulation of resin composite discoloration was prepared using A2 nanofilled resin composite immersed in coffee for 14 days and divided into 6 groups: pumice powder, Sof-Lex, Enhance/Pogo polishing system, home and in-office tooth bleaching reagents. The color values were then measured with a spectrophotometer using CIE L*a*b* system and whiteness index. Furthermore, the surface characteristics of the resin composite were studies using an Atomic Force Microscope. The data was analyzed using one-way ANOVA with post hoc Tukey’s test (p < 0.05). Results: A significant differences among groups in color values (p <0.05) compared to the controlled group were observed. The Enhance/PoGo polishing system and the Sof-Lex produced the highest color difference, while in-office bleaching resulted in the lowest color difference. However no statistically significant difference colors of all group were compared to the baseline group. Conclusion: Within the limitation of this study, Sof-Lex and Enhance/Pogo were the most effective polishing tools for coffee staining removal on resin composite.
