| Abstract There has always been a continuous search for an ideal esthetic restorative material that can restore and replace the natural tooth structure and maintain mechanical and esthetic properties. Materials and methods : in this study three recent esthetic restorative materials [ a CAD – CAM resin nano ceramic ( Lava Ultimate ) ; a nano hybrid bulk fill resin composite ( Aura) and a Universal nano hybrid ORMOCER ] ; were investigated in terms of surface roughness in relation to different pH incubation solutions. Results : The CAD – CAM resin nano ceramic Lava Ultimate and the bulk fill nanohybrid resin composite , approximately, showed close values of average surface roughness and both materials were statistically significantly superior to the Universal nano hybrid ORMOCER regarding the resistance to surface roughness in respect to all incubation solutions. Except for the CAD – CAM resin nano ceramic and regarding the other two materials ; the acidic immersion solution produced significant changes in surface roughness. | ||
