This in vitro study investigates the use of reciprocal‐action instrumentation for polishing composite resin restorative materials. Electron photomicrographs were made of surfaces of a microfilled and a hybrid composite resin restorative material polished by various reciprocal‐action polishing procedures, including several types of polishing pastes used with nonabrasive plastic tips. The best polish on the microfilled composite resin restorative material tested was produced by ending with 3‐μ diamond polishing paste. The best polish on the hybrid composite resin restorative material tested was produced by ending with 0.5‐μ diamond polishing paste. The surfaces produced were comparable to those produced by polishing discs.
