Effect of simulated tootbrushing on surface roughness of sealant agent coupled nanohybrid composite resins

Objective To investigate the effect of toothbrushing on the surface roughness (Ra) of different sealant agent coupled nanohybrid composite resins. Materials and Methods One hundred sixty disc‐shaped (10 × 2 mm) specimens were prepared from four different nanohybrid composite resins (Z‐550, Tetric Ev...

Description
Summary:Objective To investigate the effect of toothbrushing on the surface roughness (Ra) of different sealant agent coupled nanohybrid composite resins. Materials and Methods One hundred sixty disc‐shaped (10 × 2 mm) specimens were prepared from four different nanohybrid composite resins (Z‐550, Tetric EvoCeram, Clearfill Majesty, Ice). Specimen groups were divided into four subgroups for conventional polishing (control) and to apply three different surface sealant agents (Palaseal, Optiglaze, Biscover LV) (n = 10). The Ra values of the specimens were recorded before (Ra0) and after 10,000 cycles of toothbrushing (Ra1). The surface properties of the specimens were evaluated with scanning electron microscope (SEM). Data were statistically analyzed by two‐way analysis of variance (ANOVA), Tukey HSD, and paired sample t tests. Results Composite resin material, surface treatment, and their interaction were significant on Ra values (p
