Melt Derivied Fabrication Of Bioactive Glass And Biocompability Evaluation Towards Dental Pulp Stem Cell

Bioactive glass (BG) has the ability to bond to hard and soft tissues, and promotes bone growth. BG 45S5, with composition of 46.1% SiO2, 26.9% CaO, 24.4% Na2O, and 2.5% P2O5 in mole percentages (mol.%), and a new composition (BG 44S), with similar network connectivity were fabricated via melt deriv...
