Abstract

Objective: To evaluate the influence of FSSs on surface roughness of restorative materials. Materials and Methods: Eighty discs of Equia forte, Activa Bioactive composite, Cention-N, and Tetric-N Ceram Bulk Fill were prepared in a customized mold (2×10mm). The discs of each restorative material were divided into 2 subgroups as follows: one immersed in 50% aqueous ethanol (FSS1), and the other in methyl ethyl ketone (FSS2). The specimens were stored in the solutions for one week at 37oC. Surface roughness was measured before, and after immersion and the statistical analysis was performed by One Way (ANOVA) followed by post Hoc Tukey test for pairwise comparison. Percent of change was done using Z -test. Results: all the tested groups showed significance differences for ∆Ra in both FSSs. There were significance differences between FSS1 (∆Ra1) for all the tested groups, and FSS2 (∆Ra2) between Activa Bioactive and Cention-N. There was a statistical significance difference between ∆Ra 1 and ∆Ra 2 for Cention-N group. Conclusions: The effect of FSSs on alkasite based restorative material is comparable to that of the most commonly used tooth-colored direct restorative materials in clinical practice
