Background: Composite resins are widely used in aesthetic restorative procedures with commendable success rates. Good finishing and polishing procedures give the restoration an improved esthetic appearance and longevity. The final outcome after finishing and polishing depends on various factors such as the materials composition and the timing of finishing and polishing. This in vitro study assesses the surface smoothness of micro-filled hybrid composite (G-Aenial Anterior) with three commercially available polishing systems after immediate and delayed polishing.
Methods: A total of 120 identical disc-shaped specimens of a newly introduced micro-filled hybrid composite were subjected to three different polishing systems. The time to perform polishing was at two levels (immediately and after 7 days). The dependent variable was mean surface roughness (Ra, mm) (n = 20).
Results: Data were entered using the double-entry method into the STATA software version 13.1. Both Immediate and Delayed Roughness Indices of the three groups were tested by using the Shapiro-Wilks test. Analysis of variance was used to study the association between the mean of Immediate and Delayed Roughness Index among the three different polishing systems.
Conclusion: It was found that the newly introduced Soflex Spiral polishing system can give the best results when used for immediate polishing. However, Soflex Discs are best to be used in delayed polishing procedures that can be of significant value in certain restorative procedures.
