Color stability and surface roughness of polished anterior restorative materials

Abstract

The purpose of this study was to investigate the effects of different finishing-polishing techniques on the color stability and surface roughness of various anterior restorative materials after staining. A composite, a compomer, and a resin-modified glass ionomer were used to prepare 120 specimens. Specimens were divided into subgroups: polishing discs, liquid polishing material, aluminium oxidebonded discs, and control. The specimens were stained in a coffee solution. Color parameters (L*a*b*) and surface roughness before and after staining were measured. The color was affected by the material type (p<0.05) and finishing-polishing systems (p<0.05). The composite showed the highest color stability; however, the color differences of all groups were visible even to the nonskilled operator.The Ra values did not significantly change after staining for any of the restorative groups (p>0.05). The finishing-polishing systems had an effect on color after storing in staining solution.

The effect of different finishing and polishing techniques on surface roughness and gloss of two nanocomposites

“…In order to maintain or improve the aesthetic appearance of a restorative material, it is essential that the surface roughness is equal to or less than the roughness of tooth enamel in occlusal contact areas (Ferreira et al, 2015, Lainovic et al, 2014). Thus, the surface treatment with a suitable finishing and polishing technique is considered a critical procedure in order to achieve a favourable aesthetic result and to increase the longevity of the tooth restoration (Janus et al, 2010, Jefferies, 2007, Yildiz et al, 2015).…”

Effect of different surface finishing/polishing procedures on color stability of esthetic restorative materials: A spectrophotometric evaluation

“…[ 3 ] A smooth surface is clinically important as it determines the esthetics and longevity of the composite resin restorations. [ 4 ] Surface roughness seems to affect the initial adhesion of cells; moreover, gingival health is subjected to surface texture of the restoration. [ 5 ]…”

Color stability of recent composite resins

“…Within the last 2 years, several authors [6][7][8][9][10][11][12][13][14][15] have investigated the staining susceptibility of newly developed resin composite materials because of the patients' desire to receive not only functional, but esthetically pleasing restorations for a reasonable life span.…”
