Evaluation of the Surface Roughness for Three Different Types of Composite Resin Materials Using (Sof–Lex) Finishing and Polishing Systems: A Comparative Study
Abstract
Aim: To evaluate the surface roughness of three different types of light activated composite resin using (Sof-Lex) polishing system, a profilometer study. Materials and Methods: A total of 30 resin com-posite disks were prepared from three different types of composite resin include 3 groups. Group I: 10 specimens were prepared from light activated nano hybride (Tetric n Ceram, Ivoclar Vivadent Liechtenstein). Group II: 10 specimens were prepared from light activated microhybride composite resin (Arabesk Voco, Germany). Group III: 10 specimens were prepared from light activated poly-glas composite resin (Solitaire 2, Heraeus, Kulzer, Germany). The resin blocks finished and polished using (Sof Lex) polishing system. The specimens were analyzed for surface roughness using Pro-filometer. Results: Tetric n Ceram composite resin showed the lowest roughness average (0.112 m) followed by Arabesk composite (0.150 m), Solitaire 2 composite resin showed the highest roughness average (0.341 m). Conclusions: Tetric n Ceram (nano-hybride) was the best polished composite resin, showed the least roughness average.
