Abstract

Aim: This in vitro study was conducted to evaluate the effectiveness of different finishing and polishing
systems on the surface roughness of nanofilled (Z350XT) composite resin.
Materials and Methods: A total of 60 disc-shaped samples were prepared in composite resin using
standardized cylindrical metal mold (10 mm in diameter and 2 mm thick). The specimens were randomly
divided into six groups (n= 10): Group 1- Mylar strip, Group 2- Sof-Lex polishing system, Group 3- Super
Snap polishing system, Group 4- OptiDisc polishing system, Group 5- Opti1Step polishing system and
Group 6- OneGloss polishing system. The average surface roughness (Ra) of each specimen was measured
three times and the mean Ra values were determined using a surface profilometer.
Results: According to the one-way analysis of variance, surface roughness was in the following order:
Mylar strip < Super Snap polishing system < OptiDisc polishing system < Opti1Step polishing system <
SofLex polishing system < OneGloss polishing system. This difference in surface roughness was statistically
significant (P < 0.05) in all the six experimental groups.
Conclusion: Composite surface roughness depends on the composition, number of steps and flexibility of
the finishing and polishing system used.
