Background and objectives: To evaluate and compare the color stability and surface roughness of different composite resins after using different polishing systems and then submitting to accelerating artificial aging (AAA) and staining by black tea.
Method: Twenty disk-shaped specimens (were compacted into the custom-made cylindrical plastic mold that had an internal diameter of 10 mm and a depth of 2 mm) were prepared for each composite resin type (3M Z350, Tokoyama Palfique, and Shofu Beautifil II) for a total of 60 specimens, each composite group was divided into two subgroups according to the polishing system (n=10) (Shofu super-snap polishing disks and Eve Diacomp Plus Twist wheel). Color parameters (L*, a*, and b*) and surface roughness were measured before and after accelerating artificial aging (2000–4000 thermal cycles) and staining.
Results: It was observed that all resin-based materials showed an increase in color change value and surface roughness value after 2000 thermal cycles. while after 4000 thermal cycles, only the surface roughness value decreased in all resin-based materials.
Conclusion: all resin-based materials showed clinically acceptable color stability (ΔΕ < 3.7) and surface roughness >0.2 µm) after (2000 thermal cycle) and staining.
