The Effect of Prophylactic Polishing Pastes on Surface Roughness of Indirect Restorative Materials
Figure 2
(a) Scanning electron micrograph of GRD-C showed prepolymerized, ceramic, and silica fillers with some debonding. (b) GRD-DT group revealed roughening of prepolymerized fillers along with resin abrasion between the fillers. Debonding of inorganic fillers was also evident. (c) GRD-TP showed similar surface morphology as the GRD-DT, however roughening of prepolymerized fillers was not as much as that in DT group.
