Background and Objective: The purpose of this study was to evaluate the surface roughness of Nano resin composites with different polishing techniques (in-vitro study).
Method: 120 composite specimens with a 6 mm diameter and a thickness of 3 mm were fabricated from the nanofilled Filtek Z350 XT (C1) and the nanohybrid Filtek Z250 XT (C2) and equally divided into two main groups (n = 60), 20 specimens of each composite were polished with PoGo single step micro-polishers (P1), Sof-Lex multiple steps polishing system (P2) and polyester strip was used as the control group (P0), (n = 20), a profilometer was used to measure the surface roughness value after specimens’ polishing (Ra), the data were statistically analyzed using Repeated measures Analysis of Variance (ANOVA) and Bonferroni’s post-hoc test (P ≤ 0.05) was used for pair-wise comparisons when ANOVA test is significant.
Results: There was a statistically significant difference between mean Ra of different polishing systems (P-value = 0.001, Effect size = 0.269), no statistically significant difference between PoGo discs and Sof-Lex discs; both showed statistically significantly higher mean Ra than Polyester strip.
Conclusion: 1. The nanofilled Filtek Z350 XT resin composite is a good choice material for the clinical use. 2. the one-step PoGo micro-polisher produced better surface quality in terms of roughness than the multiple steps Sof-Lex polishing system.
