Finishing is defined as the gross contouring or reduction of a restoration to obtain ideal anatomy. Polishing refers to the reduction in roughness and scratches created by finishing instruments.[6] A variety of instruments such as carbide and diamond burs, abrasive finishing strips and polishing pastes may be frequently used to finish tooth-colored restorative materials.[7–10] Clinicians have their choice among a wide range of finishing and polishing instruments. Previously, significant importance was given the application of progressively finer grits of abrasives to polish resin composite restorations. Today, many attempts have been made to develop composite finishing instruments that are suitable for all four steps of the trimming procedure.[11] Current one-step systems appear to be as effective as multi-step systems for polishing dental composites.[1] With the ultimate goal of achieving a smooth surface of the composite restoration in fewer steps, the one-step polishing systems are appealing to the clinician. Because of the variety of composites and polishing systems available, they should be evaluated in order to verify which polishing systems yields the best polishing effect on a given composite. The purpose of this study was two fold: (1) To study the polishing effect of two different polishing systems: One-step (PoGo) and multi-step (Super Snap) on two different composites; and (2) To determine the surface finish of minifill-hybrid (Esthet-X) and packable (Solitaire II) composites and whether filler size and content have any effect on it.
