Özet
Purpose
The aim of this study was to evaluate the effect of a surface sealant on the surface
roughness of different composites and compare their microhardness values.
Materials and Methods
Sixty disc-shaped specimens were prepared and assigned to 6 groups (n =10).
Groups were prepared as follows; Group 1 (Herculite XRV Ultra), Group 2 (Beautifil
Bulk Restorative) and Group 3 (Filtek Bulk Fill Posterior Restorative). Groups 4, 5,
and 6 were prepared by applying a surface sealant (BisCover LV) on the specimens
in groups 1, 2 and 3. Surface hardness of the discs in group 1, 2, and 3 and surface
roughness of the discs in all groups were measured using the Vickers hardness test
and a profilometer, respectively. One-way ANOVA was used to test for differences
among the groups.
Results
No significant differences were observed in the microhardness and roughness
between the experimental and control groups for each restorative materials. Group
3 showed the highest surface hardness and group 4 showed the lowest surface
roughness values.
Conclusion
Using the BisCover LV resin after the polishing step has no significant effect on
the surface roughness. The highest hardness values were obtained for the Filtek
Bulk Fill Posterior Restorative after the polishing step. The smoothest surfaces were
obtained for all experimental groups using the BisCover LV resin after the polishing
step, Herculite XRV Ultra showed lower average roughness values than the other
materials.
