Ca and PO4 release: effect of DCPA particle size. “Whisker” refers to the silanized nano-silica-fused whiskers. DCPA was not silanized. The numbers (e.g., 12 μm, refer to the DCPA particle size). Each value is mean ± sd; n = 3. The nano-composite with DCPA particle size of 0.112 μm had significantly higher Ca and PO4 release than the other two composites with DCPA sizes of 0.88 μm and 12 μm. The hybrid control composite had no detectable Ca or PO4 release.
