The effect of powder/liquid ratio on the in vivo solubility of polycarboxylate cement.
A clinical study of the solubility of three powder/liquid ratios of polycarboxylate cement demonstrated a threefold increase in the solubility for the lower powder/liquid ratios. The three liquid/powder ratios tested were within the range recommended by the manufacturer. The data suggest that the higher powder/liquid ratio (1.5:1) is preferable when minimal solubility is a primary requirement.
