ABSTRACT
This study explores the interaction between bioactive glasses and dentin from extracted human teeth in simulated oral conditions. Bioactive glasses in the Na2O- CaO- SiO2-P2O5 and MgO- CaO- SiO2- P2O5 system were prepared as polished disks. The primary aim of the project was to develop better bio-glass-ceramics, which are bio-chemically compatible and non-toxic and to study the effect of doping agent on the physic-chemical properties of 45S5 bioactive glass , so that the end material should be bio-mechanically compatible in their mechanical harmonization with surrounding tissue, and bio-adhesive in their adhesion between the material and living tissues[3,4]. Generally, when a glass ceramic is chemically attacked, the initial effect is upon the glassy phase present. So by the addition of cerium oxide in the phosphate glass, the effects of it on chemical durability (dissolution) and mechanical properties through the analysis of glass sample using DTA, TGA, XRD, FTIR, density measurement, compressive strength measurement.
