Traditionally, glazing has always been advocated as the last surface treatment before final cementation. However, occasions will arise when porcelain restorations require adjustment in circumstances that preclude reglazing. Roughness created by adjusting the porcelain must be smoothed. The objective of this study was to compare the surface roughness (Ra) and Vickers hardness number (VHN) of porcelain (Ceramco) applied different surface treatments and to determine efficiency of the silicone polishers (Ceramiste polishers) under the simulated laboratory and clinical circumstances, with the use of scanning electron microscopy (SEM), surface profilometry and microhardness indentation tester.
