Abstract
Aim: As the spectrum of composite materials expands in the dental market, it's becoming more challenging to differentiate the structural properties and to find suitable finishing-polishing (f-p) materials. The main goal is to evaluate the impact of one and multi-step f-p systems on the surface roughness (SR) of current composite materials.
Methodology: In this study, nanohybrid bulk-fill (Filtek BulkFill Posterior [FBFP]), nanohybrid (Ceram.x One [CXO]), microhybrid (Filtek Z250 [FZ250]), and giomer bulk-fill (Beautifil Bulk Restorative [BBR]) composites were tested. After sample preparation and 24-h storage in 37 °C distilled water, each main group was assigned to one of two groups (n = 10): a one-step (One Gloss-PS) or a multi-step (Sof-Lex) f–p system. SR values (Ra, µm) were measured using a profilometer. Statistical analysis was done using Tukey HSD and ANOVA tests (p < 0.05).
Results: FZ250 showed the highest Ra values, regardless of the f–p system used. CXO showed statistically significantly lower SR scores than FZ250 (p < 0.05). There were no significant differences among the Ra values of the one- or multi-step f–p systems for FBFP and FZ250. Both the material and f–p systems had a significant effect on the Ra values separately.
Conclusion: FZ250 showed the highest Ra values, and composites polished with the multi-step f–p system exhibited slightly smoother surfaces than those polished with the one-step system.
