Effects of Protective Resin Coating on the Surface Roughness and Color Stability of Resin-Based Restorative Materials
The aim of this study was to evaluate the effects of nanofilled protective resin coating (RC) on the surface roughness (Ra) and color stability (ΔE) of resin-based restorative materials (RM) (compomer (C), nanofilled composite (NF), and microhybrid composite (MH)) after being submitted to the ultrav...

Summary: | The aim of this study was to evaluate the effects of nanofilled protective resin coating (RC) on the surface roughness (Ra) and color stability (ΔE) of resin-based restorative materials (RM) (compomer (C), nanofilled composite (NF), and microhybrid composite (MH)) after being submitted to the ultraviolet aging (UV) method. Thirty-six specimens were prepared (n=6 for each group). The Ra and (ΔE) values and SEM images were obtained before and after UV. Significant interactions were found among the RM-RC-UV procedures for Ra
(P<0.001). After the specimens were submitted to UV, the Ra values were significantly increased, regardless of the RC procedure (with RC; P<0.01 for all, without RC; C (P<0.01), NF (P<0.001), and MH (P<0.001)) for each RM. Significant interactions were found between the RM-RC (P<0.001) procedures for the ΔE values. The ΔE values were increased in each group after applying the RC procedures (P<0.001). Protective RC usage for RM could result in material-related differences in Ra and ΔE as with used UV method. |
