Abstract

Aim: evaluation of the effect of different finishing and polishing systems and the time of finishing either immediate or delayed after 24 hours on the surface roughness of bulk fill resin composite and Nano fill resin composite.

Materials and Methods: two resin composite materials were used Filtek Bulk fill resin composite and Filtek z350 Nano fill resin composite. A total of 70 resin composite specimens were prepared according to manufacturer’s instructions in specially constructed split Teflon moulds of 6 mm diameter and 2 mm thickness, specimens were divided into two main groups of 35 specimens of each composite resin, 5 specimens of each group were cured under mylar strip without any finishing or polishing procedures to serve as control group, the other 30 specimen of each composite resin was divided into 3 sub-groups of 10 specimens according to type of finishing and polishing system; one step, two steps or multiple steps, then every sub group was divided into 2 groups of 5 specimens each one according to time of finishing immediate after 10 minutes and delayed after 24 hours, each of specimens was assessed for roughness measurement by optical profilometry.

Results: In each composite group, the control had the lowest Ra.

Conclusion: Nano filled resin composite exhibited smoother surface than Bulk fill resin composite irrespective of the finishing technique used or time of finishing. Mylar strip created the smoothest surface in both materials
