| Summary: | The effect of powder-to-liquid ratio and addition of poly(ethylene glycol) on the
antiwashout behavior of calcium phosphate cement has been investigated. Calcium hydroxide,
Ca(OH)2, and diammonium hydrogen phosphate, (NH4)2HPO4, were used as precursors with
distilled water as the solvent in the wet chemical precipitation synthesis of hydroxyapatite
powder. Cement paste was prepared by mixing the as-synthesized powder with distilled water
at certain ratios, varied at 1.0, 1.3, 1.5 and 1.6. Poly(ethylene glycol) was added into distilled
water, varied at 1, 2, 3, 4 and 5 wt% using the powder-to-liquid ratio of 1.3. The antiwashout
properties of the cement has been investigated by soaking in Ringer’s solution for 3 and 7 days.
The evolution of compressive strength of calcium phosphate cement before and after soaking
have been determined. After 7 days soaking, the strength of the cement increased by 94.4%,
2.98%, 11.39% and 111.29% for powder-to-liquid ratios 1.0, 1.3, 1.5 and 1.6 respectively. The
addition of poly(ethylene glycol) up to 3% shows an increase in strength after 7 days soaking,
with 57.75%, 16.4% and 19.97% increase for 1, 2 and 3% poly(ethylene glycol) contents
respectively. The calcium phosphate cement produced in this current study shows excellent
antiwashout behavior since no cement dissolution happened and the compressive strength of
the cement increased with soaking time throughout 7 days soaking in Ringer’s solution. |
