Objective: To investigate the effect of a silane-coating material on the surface roughness of a provisional fixed prosthodontic material and compare the changes in surface roughness after brushing.

Materials and Methods: Specimens were produced from four commercial provisional restorative materials (GC Unifast Trad™, Major C&B dentine, Protemp™ 4, Luxatemp® star) and a silane-coated provisional restorative material (coated-GC Unifast Trad™) and randomly divided into control and brushing groups. A profilometer was used to determine the surface roughness of each group's specimens. The surface morphology of the specimens from each group was examined using a scanning electron microscope (SEM).

Result: The roughness of the control groups was not significantly different. In the brushing groups, the coatedGC Unifast Trad™ roughness was significantly lower than that of GC Unifast Trad™. Furthermore, the coatedGC Unifast Trad™ roughness was not significantly different compared with Protemp™ 4 and Luxatemp® star.

Conclusion: The surface roughness of acrylic resin coated with a silane-SiO2 nanocomposite film is similar to that of conventional acrylic resin and bis-acryl composite resin. In contrast, the roughness of conventional acrylic resin is higher compared with coated acrylic resin after brushing, and acrylic resin coated with a silane-SiO2 nanocomposite film also has a roughness similar to that of bis-acryl composite resin.
