| Summary: | Objective: The objective of this study was to evaluate the effect of different surface treatments on the pigmentability of the
ceramic after immersion in staining solution. Materials and Methods: 44 disks of 10 mm radius and 3 mm thickness were
made. Samples were randomly assigned among 4 experimental groups (n=11) receiving surface treatment according to the
different groups M, H, B, L. (n=10) were distributed for color evaluation and Roughness (RU) and a sample of each group
used for scanning electron microscopy (SEM) analysis. For (RU), the data were subjected to ANOVA on ranks (α=0.05), and
for the color ANOVA a factor (α=0.05). In the microphotographs of the surface, a qualitative/descriptive analysis was carried
out. Results: In the (RU) compared before and after immersion for each group, no statistical difference was observed (p>
0.05). When comparing the types of polish before immersion, a difference was observed between the L group with the other
M, H, B (p <0.05). In the analysis of the groups after immersion, there was a difference of group L with B and M (p <0.05).
When comparing the color alteration, after immersion, there was a difference between all the ANOVA groups (p <0.05). In
the analysis by (SEM) all groups had partially porous surfaces; however, the varnishes produced the best result groups H
and B. Conclusions: The texture of the surface is an important factor in the pigmentability of ceramics. the varnished
materials showed less color alteration |
