“…Pre-roughening with diamond burs results in a non-homogeneous surface texture 22) and creates different surface roughnesses on different materials 22,27) . Therefore, in this study, pre-roughening was standardized using a polishing machine with 320-grit SIC paper that generated roughness similar to that created with a 30/40-µm diamond bur, which represents clinical contouring and finishing 22) . With both polishing systems, according to the manufacturer's instructions, the finishing step was accomplished in 20 s and the polishing step was completed in 40 s. To eliminate inter-individual differences in manual polishing that could substantially affect the results, all of the finishing and polishing procedures were performed by the same operator.…”

“…Each polisher was used only once, with the same low-speed hand piece (Kavo 80E, Kavo Dental, Charlotte NC, USA) for all specimens. Prior to polishing the specimens, composite surfaces were pre-roughened with 320-grit silicon carbide (SIC) paper for 30 s 10,22) . Pre-roughening was standardized using a polishing machine (Buehler, IL, USA) at a rotation speed of 400 rpm, and constant moving action was applied under water coolant to prevent heat build-up.…”

The purpose of this study was to investigate surface roughness (Ra) and morphology of supra-nanofilled [Estelite Omega (EO), Estelite ∑ Quick (EQ)], micro-hybrid [Esthet.X HD (EHD), G-aenial (GAE)] and nano-hybrid [Clearfil Majesty Posterior (CMP), Charisma Diamond (CD), Beautifil II (BII)] composites polished with two-step polishing systems [Enhance/PoGo (EP); Venus Supra (VS)]. Composite discs, 30 of each type, were prepared. Each composite group was divided into three subgroups: Mylar (control), EP and VS. Ra was evaluated with profilometer. In each composite group, the control had the lowest Ra. With both polishing systems, EO and EQ had significantly the lowest Ra, whereas CMP and BII had the highest. Except for GAE, CD and BII, the differences in Ra between EP and VS in each composite group were significant, showing smoother surfaces for EP. Supra-nanofilled composites created smoother surfaces than nano-hybrids, and their performance was similar or slightly better than that of micro-hybrids.

“…These materials are claimed to offer reduced polymerization contraction, enhanced mechanical characteristics, and improved esthetics [17][18][19][20] . Nanofill composites are formulated with both nanomer and nanocluster filler particles, whereas nanohybrid composites are hybrid resin composites containing finely ground glass filler and nanofiller in a prepolymerized filler form 14) .…”

Surface texture and roughness of polished nanofill and nanohybrid resin composites

et al. 2010

Nanofiller-containing resin composites have gained appreciable market share in dentistry due to their claims of high mechanical strength and low polymerization contraction. In this study, the polishability of one nanofill (Filtek Supreme XT/FIL) and three nanohybrid materials (Grandio/GRA, Tetric EvoCeram/TET, Venus Diamond/VED) was investigated using surface profilometry and SEM. After the specimens were cured under a Mylar strip or pre-ground with 600-grit SiC paper, three polishing systems were applied and their polishing effects compared: diamond polishing points, a diamond paste, and urethane-backed aluminum oxide disks. Except for the profilometry results obtained by glass filler-containing GRA and VED with one polishing system that comprised the consecutive application of diamond particles and a diamond polishing paste, the final roughness (Ra) of all other specimens were lower than the clinically acceptable 0.2 µm threshold. The surface textures of the polished nanofill FIL and nanohybrid TET were uniformly smooth, whereas relief polishing effects and filler extrusion of varying extents were seen on the nanohybrid composites GRA and VED.
