Book Description
Objectives: To evaluate the surface roughness of a nanocomposite and a microhybrid composite after polishing the composites with different polishing systems. Key words: Polishing, surface roughness, microhybrid composite, nanocomposite, Sof-Lex XT, Spiral Wheels, Enhance, Intensiv UniglossCellbrush, Zircon-Brite, Dura-White stones, Mylar strips Methods: The composites used in this study were Filtek Supreme XTE (3M ESPE, St Paul, USA) and Z100 (3M ESPE, St Paul, USA). Thirty-five composite samples were made from each of the two composites. Uncured composite was placed into an aluminium ring mould, 10mm X 2mm. Both the upper and lower surfaces of the composite were covered with Mylar strips and glass plates, before the specimens were cured for 40 seconds from both sides. Samples were randomly divided into seven groups. The groups were: 1. Mylar polyester strip (control) 2. Sof-Lex XT finishing and polishing discs (3M ESPE, St Paul, USA) 3. Sof-Lex Spiral Wheels (3M ESPE, St Paul, USA) 4. Dura-White stones (Shofu Inc, Kyoto, Japan) 5. Intensiv UniglossCellbrush (Intensiv SA, Montagnola, Switzerland) 6. Enhance finishing and polishing system (Dentsply, Milford, USA) 7. Sof-Lex Spiral Wheels combined with Zircon-Brite (Dental Ventures of America, Corona, USA) The polishing of the specimens was performed by a single operator according to manufacturer s instructions. The mean surface roughness of each specimen was determined using a profilometer (Surftest SJ 210, Mitutoyo, Tokyo, Japan). Three readings were collected from each specimen. Data was statistically analysed using ANOVA. Scanning Electron Microscope (JEOL JSM-5800 LV, Tokyo, Japan) photos were taken of the representative samples. Results: Statistically significant differences in surface roughness were observed between the following groups: Z100 and Filtek Supreme XTE with the polishing systems combined (p=0.005); Control group vs all the polishing systems; Sof-Lex XT finishing and polishing discs vs Dura-White stones, Intensiv UniglossCellbrush, Enhance finishing and polishing system (p
