| Summary: | Calcium silicate based cements have been used widely in endodontic and tissue
engineering because their ability to induce bone-like formation in human body.
Commercial Portland cement which normally used as material in construction was
studied to form a bioactive material. Apatite is a calcium phosphate which
deposited on surface of bioactive material once immersed in physiological fluid.
In this experiment, Simulated Body Fluid (SBF) was used as a tool to test
bioactivity of Portland cement. SBF is a solution which the ion concentration
almost equal to human blood. This experiment conducted by immersing cement
paste in SBF for 1, 3 7 and 14 days in water bath shaker at 37°C. Cements were
refreshed for every 3 days. A comparison between SBF and 1.5 SBF have been
made to analyze cement bioactivity. Mass loss, pH and FTIR are the parameters.
From the results, it can be concluded that cements possessed high possibility in
inducing apatite in both SBF solutions based on the band at 1400 cm-I (C032
-) ,
572 cm- (P-O) and 602 cm-I (P-O) on FT-IR spectra Those functional groups are
the part of components for formation of apatite. |
