| Abstract Aim: to achieve the surface roughness of bulk-fill composite resins based on ORMOCER and methacrylate. Materials and method: In this research, A total 24 specimens had been utilized in this work, were split to 2 groups (n=12) based on to the form of composite resin (Group I: bulk-fill composite resin based on ORMOCER and Group II: bulk-fill composite resin based on Methacrylate). Each group was subjected to surface roughness. Statistical analysis by, Mann-Whitney test to compare two groups, was utilized, then a Wilcoxon W test is performed. At p < 0.05, the significant threshold was established. A standardized cylindrical mold (polytetrafluoroethylene) had been utilized to fabricate the bulk-fill resin composite species which were examined prior and following wear stimulation and photographed utilizing a 3D-surface analyzing system. Results: The mean Ra scores of the Aura bulk fill composite samples' surfaces were greater comparing with that of the Admira fusion x-tra composite samples' surfaces, where Ra is a measure of the arithmetic mean of all profile deviations throughout the mean sampling length in μm. Following wear simulation, group II (Aura bulk fill) obtained the higher ΔRa mean value (0.0031±.0066 μm) followed by group I (Admira fusion x-tra) (0.0016± .0032 μm). Statistics showed that there was no variance across all groups (p > 0.05). Conclusion: Composites made of methacrylate and ORMOCER are both susceptible to surface roughness after aging and wear stimulation. Considering that Admira Fusion X-tra has the lower surface roughness. | ||||
