Comparative Evaluation of Surface Roughness of Three Different Composite Resins Following Polishing with a Two-Step Technique
Background and Aim: Nowadays, demand for same–color restorative materials, especially resin composites, is increasing. Access to the smooth surface with minimum level of surface roughness significantly results in more beauty, and the reduction of the accumulation of the plaque, gingival inflammation, and tooth discoloration. the aim of this study was surface roughness of three different composi...
متن کاملThe effect of one-step and multi-step polishing systems on the surface roughness and microhardness of novel resin composites
OBJECTIVES The objective of this in vitro study was to evaluate the surface roughness and micro-hardness of three novel resin composites containing nanoparticles after polishing with one-step and conventional multi-step polishing systems. METHODS A total of 126 specimens (10 X 2 mm) were prepared in a metal mold using three nano-composites (Filtek Supreme XT, Ceram-X, and Grandio), 21 specime...
متن کاملComparison of One-Step and Multistep Polishing Systems for the Surface Roughness of Resin Composites
Aim: This study analyzed the effect of different finishing and polishing systems on the surface roughness of a microfilled (Amaris), and a nanofilled resin composite (Clearfil Majesty Esthetic) using Scanning electron microscope (SEM) analysis and surface roughness tester. Materials and Methods: Thirty five specimens of each material were prepared in a plexiglass mold (10 mm in diameter and 2 m...
متن کاملSurface roughness of composite resins after finishing and polishing.
This study evaluated the effect of surface finishing methods on the average surface roughness of resin composites. Seven composites and two polishing systems were used. One hundred and twenty-six conical specimens of each material were prepared in stainless steel molds against a polyester strip. Forty-two of them remained intact and were used as controls. Each half of the remaining samples was ...
متن کاملModeling Dielectric Erosion in Multi-Step Copper Chemical-Mechanical Polishing
A formidable challenge in the present multi-step Cu CMP process, employed in the ultra-large-scale integration (ULSI) technology, is the control of wafer surface non-uniformity, which primarily is due to dielectric erosion and Cu dishing. In contrast with the earlier experimental and semi-theoretical investigations, a systematic way of characterizing and modeling dielectric erosion in both sing...
