Abstract

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

不同表面处理和抛光系统对高美观度复合材料表面粗糙度和显微硬度的影响
摘要 目的:本研究旨在通过三维光学轮廓仪、维氏显微硬度计和扫描电镜分析,研究三种不同类型的高美观性复合树脂对表面粗糙度和显微硬度的影响。 材料和方法:研究中使用了三种不同的复合树脂:超纳米薄膜(Tokuyama Estelite Asteria)、超纳米球形(Tokuyama Omnichroma)和纳米混合(Kuraray Clearfil Majesty Esthetic)。每种复合树脂制备了 40 个样品,共 120 个样品。聚合和修正过程结束后,从每组中选出 10 个未经过任何抛光过程的样品作为对照组。然后,将它们随机分为三组进行抛光处理:4 级氧化铝涂层盘(3M Sof-lex 盘)、米色和粉色 2 级含氧化铝金刚石颗粒的螺旋橡胶(3M Sof-lex 螺旋橡胶)、聚氨酯、含金刚石颗粒的浅蓝色橡胶和螺旋橡胶(Ivoclar Vivadent OptraGloss)。用传统的轮廓仪测量所有样品的表面粗糙度(Ra)。然后,用光学轮廓仪和扫描电子显微镜检查每组中的一个样品表面,并用维氏硬度计对所有样品进行显微硬度测试。 结果研究结果表明,对照组的粗糙度值最低,而使用 Ivoclar Optragloss 的组的粗糙度值最高。与其他复合材料组相比,使用可乐丽Clearfil Majesty Esthetic复合材料的研究组显示出更高的粗糙度值,但与其他复合材料组相比,没有发现明显的统计学差异(P>0.05)。在我们的研究中,对照组的显微硬度值最低,而 Sof-Lex Disk 组的显微硬度值最高。使用可乐丽 Clearfil Majesty Esthetic 复合材料处理的组别与其他复合材料组别之间的差异具有统计学意义(p<0.05)。
