Effect of three polishing systems on the roughness and glossiness of nanoceramic composite resin

Objective: The purpose of resin polish is to produce a restored surface that is similar to that of enamel. The objective of this study was to analyze the polishing effect of three systems in terms of the comparative roughness or glossiness achieved with nanoceramic composite resin. Methods: Forty samples of nanoceramic composite resin were divided into four groups as follows: Group 1 was the control group, which involved polymerization using Mylar strips; Group 2 involved a one-step polishing method; Group 3 involved a two-step method; and Group 4 involved a four-step method. After performing these methods, the comparative roughness and glossiness of the resulting surfaces were measured. Results: Group 4 generated the lowest roughness value, with an almost equal value to that of the control group, which was followed by Group 3 and Group 2. The best surface in terms of glossiness was achieved in Group 4. Conclusion: The polishing system involving the four-step method generated the lowest roughness value and the highest surface glossiness value.
