Mean surface roughness of the acrylic resins at baseline and following surface treatments. Different lower case letters within the material groups indicate statistically significant differences (p<0.001) between the materials for the disinfectant used. CAD/CAM, computer-aided design/computer-aided manufacturing; CHG, chlorhexidine gluconate; HC, heat-cured resin; LC, light-cured resin; RT, roughness threshold (0.2 μm).
