“…However, an arithmetic average roughness can be calculated and used to represent various material-polishing surface combinations that assist clinicians in their treatment decisions. [2325] However, the complex structure of a surface cannot be fully characterized by the use of only surface roughness measurements. Therefore, it is not appropriate to draw conclusions on the clinical suitability of a finishing instrument exclusively on the basis of roughness average results.…”

Objective:The purpose of this in-vitro study was to evaluate the surface roughness of two direct resin composites polished with one-step and multi-step polishing systems.Materials and Methods:The resin composites examined in this study include minifill-hybrid composite Esthet-X (DENTSPLY/Caulk, Milford, DE, USA) and packable composite Solitaire II (Heraeus Kulzer, Inc., Southbend). A total of 42 discs (10 × 2 mm), 21 specimens of each restorative material were fabricated. Seven specimens per composite group received no polishing treatment and served as control. For each composite group, the specimens were randomly divided into two polishing systems: One-step PoGo (Dentsply/Caulk, Milford, DE, USA) and multi-step Super Snap (Shofu, Inc. Kyoto, Japan). Polishing systems were applied according to the manufacturer's instructions after being ground wet with 1200 grit silicon carbide paper. The surface roughness values were determined using a profilometer.Results:Data was subjected to student's t test at a significance level of 0.05. The smoothest surfaces were achieved under Mylar strips in both the composite groups. Mean Ra values ranged from 0.09 to 0.3 μm for Esthet-X group and from 0.18 to 0.3 μm for Solitaire II with different polishing systems. The ranking of the order of surface roughness on the basis of the type of composite was as follows: Esthet-X < Solitaire II for PoGo system and Esthet-X = Solitaire II for Super Snap; and the ranking for the polishing system was: PoGo < Super Snap (P ≤ 0.05).Conclusion:The one-step polishing system (PoGo) produced better surface quality in terms of roughness than the multi-step system (Super Snap) for minifill-hybrid composite (Esthet-X), and it was equivalent to Super Snap for packable composites (Solitaire II). Minifill-hybrid presented a better surface finish than Solitaire II when PoGo polishing system was used. No significant difference was present in surface roughness between both the materials when Super Snap system was used.

SUMMARYObjectives: This study: 1) analyzed the surface roughness of five novel resin composites that contain nanoparticles after polishing with three different one-step systems and 2) evaluated the effectiveness of these polishers and their possible surface damage using scanning electron microscope (SEM) analysis. The samples were polished for 30 seconds with PoGo, OptraPol and One Gloss discs at 15,000 rpm using a slow speed handpiece. The surfaces were tested for roughness (Ra) with a surface roughness tester and examined with SEM. Oneway ANOVA was used for statistical analysis (p=0.05). MethodsResults: For all the composites tested, differences between the polishing systems were found to be significant (p<0.05). For Filtek Supreme XT, Mylar and PoGo created equally smooth surfaces, while significantly rougher surfaces were obtained after OptraPol and One Gloss applications. For Grandio, Mylar and PoGo created equally smooth surfaces, while OptraPol and One Gloss produced equally rougher surfaces. Tetric EvoCeram exhibited the roughest surface with OptraPol, while no significant differences were found between Premise and Ceram X. According to SEM images, OptraPol and One Gloss scratched and plucked the particles away from the surface, while PoGo created a uniform finish, although the roughness values were not the same for each composite.

“…mentioned that the smoothest surface of a composite resin is produced when restoration is cured against a Mylar strip. [620] Pre- and post-instrumentation roughness were calculated in terms of Ra values (μm). Ra can be defined as the arithmetic mean of the departure of the profile from a mean line derived from the top and bottom of the undulations on the trace.…”

Aims:This study evaluated the effect of ultrasonic scaling on surface roughness of four different tooth-colored class V restorations.Materials and Methods:Out of 100 human extracted teeth, 20 were randomly selected for each group, marked with the outline of class V cavity. Class V cavities were prepared on facial surface of teeth of all groups except control group. These cavities were then restored with GC 2, GC 9, GC 2 LC, and Filtek Z 250 XT. All the specimens were stored in artificial saliva at 37°C for 1 month. Initial surface roughness values (Ra in μm) of restorations were evaluated with the surface roughness tester. Ultrasonic instrumentation was then carried out for 60 s on the restoration surface and final roughness values were evaluated. Data were analyzed with Paired t-test, One-way ANOVA, Tukey's test.Results:Mean Pre-instrumentation surface roughness was highest with GC 2, whereas it was least in case of Filtek Z 250 XT. Mean post-instrumentation surface roughness was highest with GC 2, whereas it is least in case of Filtek Z 250 XT.Conclusion:GC 2 LC showed highest and Filtek Z 250 XT showed least susceptibility to ultrasonic scaling.
