Influence of additional polishing on the surface texture of esthetic restorative materials in different mouth rinses: An in vitro study

Abstract

Purpose: This study evaluated the influence of additional polishing procedures on micro-hybrid and nano-hybrid resin composites immersed in two different mouth rinses. Materials and methods: Ninety specimens from each restorative material (Esthet.X HD, Dentsply, Filtek LS, 3M-ESPE, Beautifil II, SHOFU and Tertic N-Ceram Ivoclar Vivadent) were prepared and immersed in distilled water for 24 h. Baseline surface roughness was recorded using a Digital Microscope. Specimens from each material were divided into Group 1 (control) celluloid matrix; Group 2 polished by Kerr disks, and Group 3 polished by Kerr disks followed by silicon carbide brushes. Each group was subdivided into 3 subgroups (n=10) immersed in either artificial saliva, Listerine or Antiseptol and incubated for 24 h at 37°C. The post immersion surface roughness values were recorded for statistical analysis. Results: Control groups recorded significantly lower roughness (p < 0.05), while both polishing techniques gave similar roughness values. No significant difference was found between immersion media or between resin composites. However, nano-hybrid composites showed statistically higher roughness after polishing compared to control group. Conclusions: The surface texture of tested composites is neither influenced by polishing techniques nor rinses.
