Article Title: Layer-Matched A2 Shade Compatibility Across 3Y/4Y/5Y Multilayer Zirconia: CIEDE2000 Color Differences Correlated with Y 2 O 3 Content (EDS), Phase Constitution (XRD), and Grain Size (FE-SEM)
doi: 10.3390/dj14040226
Figure Lengend Snippet: Representative FE-SEM micrographs of thermally etched zirconia surfaces (10,000×). ( a ) UTML (5Y), ( b ) STML (4Y), and ( c ) HTML (3Y). Scale bar = 1 µm. ( d ) Mean grain size (µm) of UTML, STML, and HTML zirconia determined using the line-intercept method. Bars represent mean ± SD. Different letters indicate statistically significant differences between zirconia grades (Welch ANOVA, p < 0.001; post hoc pairwise comparisons, p < 0.001).
Article Snippet: Micrographs were acquired using a JSM-7800F field-emission scanning electron microscope (FE-SEM) (JEOL Ltd., Tokyo, Japan).
