dc.description.abstractPurpose This study aimed to investigate the effect of surface treatment and type of composite resin material on the color stability and surface roughness of different denture characterizing composites. Materials and methods Two nanohybrids [Gradia Plus Gum, (GP) and SR Nexco Paste Gingiva, (SR)] and one microhybrid gingiva-colored composite resin [Amaris Gingiva, (AG)] were investigated. A total of 120 disk-shaped samples were prepared, 40 of each material. Samples were divided into two groups (n = 20) for each material according to the surface treatment applied: conventional polishing (control) and coated with a sealant in addition to the surface polishing. All groups were thermocycled. The surface roughness (Ra) was measured using a profilometer after thermal cycling. The samples were then divided into 2 subgroups (n = 10) and stored for 7 days in distilled water or coffee solution. Color differences (Delta E-00) were calculated with a spectrophotometer. Results were evaluated with Kruskal-Wallis and Mann-Whitney U statistical analysis. Results The type of denture characterizing composite material and surface treatment method revealed statistically significant differences for the Delta E-00 (after immersion both in coffee and distilled water) and the Ra values of denture characterizing composite (p < 0.001 for both). All sealed groups showed significantly higher Ra than the all polished groups. Both in the polished groups and the sealant applied groups, the GP had the highest mean Ra values (0.29 +/- 0.05 mu m and 0.47 +/- 0.09 mu m, respectively). It was followed by SR (0.23 +/- 0.06 mu m and 0.41 +/- 0.10 mu m, respectively), and AG groups (0.20 +/- 0.06 mu m and 0.39 +/- 0.09 mu m, respectively). According to the mean Delta E-00 results, all composite groups showed significantly higher Delta E-00 values immersed in coffee solutions compared to distilled water. In coffee solutions, the highest Delta E-00 was observed in the polished GP (1.90 +/- 0.40), and the lowest Delta E-00 was observed in the polished SR (0.97 +/- 0.36). The sealed groups showed higher Delta E-00 than the polished groups, except for GP. Conclusions The surface roughness value of sealant applied groups were significantly higher than those of the polished groups. The surface sealant application significantly increased the staining of all composite groups compared to conventional polishing, except for GP.
