PURPOSE. This study was to evaluate the effect of repeated ultrasonic scaling and surface polishing with intraoral polishing kits on the surface roughness of three different restorative materials. MATERIALS AND METHODS. A total of 15 identical discs were fabricated with three different materials. The ultrasonic scaling was conducted for 20 seconds on the test surfaces. Subsequently, a multi-step polishing with recommended intraoral polishing kit was performed for 30 seconds. The 3D profiler and scanning electron microscopy were used to investigate surface integrity before scaling (pristine), after scaling, and after surface polishing for each material. Non-parametric Friedman and Wilcoxon signed rank sum tests were employed to statistically evaluate surface roughness changes of the pristine, scaled, and polished specimens. The level of significance was set at 0.05. RESULTS. Surface roughness values before scaling (pristine), after scaling, and polishing of the metal alloys were 3.02±0.34 μm,2.44±0.72 μm, and 3.49±0.72 μm, respectively. Surface roughness of lithium disilicate increased from 2.35±1.05 μm (pristine) to 28.54±9.64 μm (scaling), and further increased after polishing (56.66±9.12 μm, P<.05). The zirconia showed the most increase in roughness after scaling (from 1.65±0.42 μm to 101.37±18.75 μm), while its surface roughness decreased after polishing (29.57±18.86 μm, P<.05). CONCLUSION. Ultrasonic scaling significantly changed the surface integrities of lithium disilicate and zirconia. Surface polishing with multi-step intraoral kit after repeated scaling was only effective for the zirconia, while it was not for lithium disilicate.
