| Purpose: To investigate and compare the impact of casin phosphopeptide-amorphous calcium phosphate with fluoride (CPP-ACPF) and sodium fluoride, remineralizing pasts, on surface texture of four different resin composites. Methods: 20 disc specimens (5 mm × 2 mm) were prepared from each of four resin composites that belong to the categories of conventional (Filtek Z250 XT; F250), flowable (Filtek Z350 XT; F350), high viscosity bulk-fill (Filtek Bulk Fill Restorative Posterior; FBF), and self-adhering flowable (Vertise Flow; VF). After polishing, the specimens of each material were divided into four groups (n=5): group 1: without treatment, dry-stored; group 2: without treatment, water-stored; group 3: treated with GC Tooth Mousse Plus (TMP) 15 min/once daily and stored in distilled water; and group 4: treated with Clinpro White Varnish (CWV) 15 min/once daily and stored in distilled water. All specimens were stored for 15 days at 37οC. The surface roughness was determined using non-contact 3D Optical Profiler. Three exposures were performed on top surface of each specimen. Statistical analysis was performed using ANOVA followed by Tukey HDS. Results: For all materials investigated; the roughness values of TMP-treated group were not affected (P > 0.05) compared to control group, while they were significantly (P < 0.001) reduced compared to water-stored, except for VF. However, the roughness values of CWV-treated group were significantly (P < 0.001) increased compared to both control and water-stored groups, for all materials. The values of all roughness parameters of TMP-treated group of each composite tested were significantly (P < 0.001) lower than those of CWV-treated group, except for Sp and Sv parameters regarding VF. Conclusions: TMP produced a significant surface smoothening of nano-composites used in this study, while CWV caused a significant increase in roughness values of all materials. Topical application of TMP could be used clinically without adverse effects on surface texture of resin composites. | ||||
