Abstract

Aim: The present study aims to assess the color stability of nano-filled composite resin polished using three different polishing systems (Sof-lex, Enhance, and mylar strip) and stained with commonly consumed discoloring agents (tea, dal, and Coca-Cola) in India.


Materials and Methods: 120 Disc-shaped samples were prepared and divided into polishing groups, with each group subjected to specific polishing procedures. After baseline measurements, samples were immersed in staining solutions, and color differences were measured by a spectrophotometer to assess discoloration.


Results: Statistical analysis revealed significant staining differences among the polishing groups (P<0.001 by ANOVA). Group 3 (Enhance) exhibited higher staining compared to Group 2 (Sof-Lex). Dal caused significantly greater staining compared to other agents in all groups. The staining potential of beverages ranked as Dal > Tea > Distilled water ≥ Coca-Cola.


Conclusion: This study highlights the impact of polishing systems on the color stability of nano-filled composite resin restorations when exposed to common discoloring agents. The findings underscore the importance of selecting appropriate finishing and polishing techniques to mitigate discoloration risks, particularly in the context of varied staining potentials of different agents. This knowledge contributes to improving clinical practices for enhancing the long-term aesthetic outcomes of composite resin restorations in dental applications.
