Description:	In the present work, we studied dissolution behavior of three glass ceramics samples each having 34 SiO 2–14.5 P 2 O 5–1 CaF 2–0.5 MgF 2 (% wt) and ratio of CaO/MgO varying from 11.5: 1 to 1: 11.5 in conventional SBF (SBF-K9) and revised SBF (r-SBF) that has ionic concentration exactly equal to that of human blood plasma. For that purpose, samples were immersed in fluids for different time periods upto 25 days. Thin film XRD analysis revealed the diffusive nature of the phases on the surfaces of samples after soaking for different time periods in r-SBF. It showed the poor precipitation and small thickness of the HCAp layer on the samples as compared to that in SBF-K9, thus indicating the fitness and sensitivity of r- SBF for in-vitro characterization of samples.
