Evaluation of the surface roughness for three different types of composite resin materials using (Sof–Lex)‎ finishing and polishing systems : a comparative study

Abstract EN

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 μm) followed by Arabesk composite (0.150 μm), Solitaire–2 composite resin showed the highest roughness average (0.341 μm).

Conclusions : Tetric n–Ceram (nano-hybride) was the best polished composite resin, showed the least roughness average.
