Corrosive-Wear and Related Properties of ICE and ROKLSU School of Dentistry, 1100 Florida Avenue, New Orleans, LA 70119.<\/p>\n The aim of this study was to evaluate the resistance to corrosive wear of ICE and ROK and data were compared those of three popular brands, POINT 4 (Kerr-Sybron), Esthet (Caulk) and Supreme (3M\/Espe). The corrosive wear had been simulated in two steps:<\/p>\n A. CORROSION – Samples were exposed to 0.1 N NaOH (Sodium hydroxide) solution enriched with OH- at 60oC for two weeks. They were then washed and dried at 60oC. Each was measured for (i) Mass-loss (gravimetrically) (ii) Si-loss (ICP-AE) and (iii) Degradation depth (microscopically). The degrade surface of each brand was also characterised by scanning electron microscopy (SEM).<\/p>\n B. WEAR \u2013 Test composites were filled into ceramic discs and polished to a flat surface. Samples were then corroded as above. Corroded specimens were abraded in a tooth-brushing machine. The wear depth was measured relative to the ceramic disc.<\/p>\n Results:[\/vc_column_text][vc_column_text]<\/p>\n\n
