| Summary: | The aim of this study is to investigate the effect of acidic calcium phosphate
solution concentration in fabricating dicalcium phosphate dihydrate (DCPD) coated
on β-TCP pellets. β-TCP pellets were exposed to an acidic calcium phosphate solution
for 1, 3 and 5 hours in order to obtain DCPD-coated layer on β-TCP pellets through
dissolution-precipitation reaction. Several characterization methods such as X-Ray
Diffraction (XRD), Fourier-Transform Infrared Spectroscopy (FTIR), Scanning
Electron Microscope (SEM), Atomic Force Microscope (AFM), porosity analysis and
compression test were carried out on specimen. The analyses of XRD and SEM
showed that the amount of DCPD crystal precipitated on the pellets were increased
when increasing the acidic calcium phosphate solution concentration. Increasing the
amount of DCPD formation will reduced the porosity until 20% and increased the
mechanical strength of specimen up to 40%. Meanwhile, XRD and SEM analyses
showed that hydroxyapatite (HAp) formation were increased after increasing the
soaking time of β-TCP pellet treated for 3 hours using different concentration of acidic
calcium phosphate solution in Hank’s Balanced Salt Solution (HBSS). Therefore,
based on this study shows that the amount of DCPD coated on β-TCP pellet could be
regulated by changing the concentration of acidic calcium phosphate solution that
induced HAp formation at physiological body condition. |
