Objective:
Aim of study was to produce a series of aluminum ions free silicate based bioactive glasses with substitution of calcium with strontium and barium (46.14 SiO2.2.60 P2O5.23.95 CaO.24.35 Na2O.1.5X1.1.5X2 (X1= SrO and SrF2) and (X2= BaO and BaF2) to analyse biological & mechanical properties of GIC based on modified bioactive glasses.
Methods:
Series of silicate based bioactive glasses were synthesised using melt quenching technique, incorporated in the synthesis of GIC after introduction of citric acid as setting modifier with admixture of poly-acrylic acid and water. Prepared glass samples were characterised physically by using XRD. Synthesised citric acid-based cement samples were further characterised based on their chemical, biological and mechanical properties using Raman, FTIR, MTT assay, Compressive strength measurement and Gilmore needle test respectively.
Results:
It is concluded that all prepared GIC samples exhibit improvement in biological & mechanical properties, can significantly be used in both medical and dental applications. |
