Initial Ca and P ion release (mean ± sd; n = 6) from the adhesive specimens. Ca and P ion release of adhesive PEH (C, D) and adhesive PEHB (E, F) were significantly higher than that of adhesive PE (A, B) with the same NACP content (p < 0.05). The released ion concentration was plotted as the total accumulative ion concentration versus time. Increasing the NACP content substantially increased the Ca and P ion release (p < 0.05)
