ABSTRACT
Objectives: The aim of this study is to examine the effect of three different types of highly esthetic composite resin, which will be used for aesthetic purposes in the anterior region, on the surface roughness and microhardness by the application of three different finishing and polishing systems, with three-dimensional Optical Profilometer, Vickers microhardness device and SEM analysis.
Materials and methods: Three different composite resins were used in the study; supra-nanofil(Tokuyama Estelite Asteria), supra-nano spherical(Tokuyama Omnichroma), nanohybrid(Kuraray Clearfil Majesty Esthetic) were used. 40 samples of each composite resin were prepared, 120 in total. After the polymerization and correction processes, ten samples from each group that did not undergo any polishing process were separated as the control group. Then, they were randomly divided into three groups for the polishing process: 4-stage aluminum oxide coated disc(3M Sof-lex disc), beige and pink 2-step spiral rubber consisting of aluminum oxide-containing diamond particles(3M Sof-lex spiral), polyurethane, diamond granules. containing light blue rubber and spiral rubber(Ivoclar Vivadent OptraGloss). Surface roughness(Ra) was measured on all samples with a conventional profilometer device. Then, one sample surface from each group was examined with the Optical Profilometer device and the Scanning Electron Microscope, and all samples were subjected to microhardness testing with the Vickers Microhardness Tester.
Results: As a result of our study, the lowest roughness values were observed in the control group, while the highest roughness values were observed in the Ivoclar Optragloss group. The groups studied with Kuraray Clearfil Majesty Esthetic composite showed higher roughness values compared to other composite groups, but no statistically significant difference was found with other composite groups(p>0.05). In our study, the lowest microhardness values were observed in the control group, while the highest microhardness values were observed in the Sof-Lex Disk group. The difference between the groups treated with Kuraray Clearfil Majesty Esthetic composite and the other composite groups was found to be statistically significant(p<0.05). The lowest microhardness values were observed in the groups treated with Kuraray Clearfil Majesty Esthetic composite.
Conclusions: It was observed that the effectiveness of the polishing systems used on different restorative materials was different, and when the polishing systems were compared, the Soflex multi-stage disc system and the Soflex two-stage spiral tire system were found to be more successful.
