Figure 2. Composite wear rates vs. nano-silica-fused whisker filler level. (A) Wear scar depth WD, (B) wear scar diameter WL, and (C) wear scar volume WV. Data for the prosthetic and inlay/onlay composite controls were included in each plot near the right axis. Each value is the mean of 6 measurements, with the error bar showing 1 standard deviation (mean ± SD; n = 6). The line through the data for the whisker composites was the linear best fit with the equation and the correlation coefficient R shown in each plot.
