This study investigated the effect of adding bioactive glass 45S5 (BG) different particle sizes to dental composite on resin polymerization and shrinkage stress formation. Commercial flowable was mixed with either 15 wt% BG fillers (nanometric, micrometric, or hybrid BG) inert barium glass. Real-time linear were recorded, degree conversion measured using FTIR spectroscopy. The commercial (unmod...

As also observed for conventional silicate glasses, water can be incorporated in the bulk interstitial regions of a bioactive glass (BG) matrix during the glass preparation and/or upon exposure to an aqueous environment. However, in the case of BGs, very little is known about the effect of hydration on the bulk structure, and then on key properties of these materials, such as biodegradation and...

Abstract Although the initial in vitro dissolution of bioactive glasses (BAG) is well characterized, long-term behaviour crystallized BAG scaffolds a continuous fluid flow incompletely understood. A detailed understanding vital for predicting their clinical applications. Here, we explored and reaction mechanisms partly crystalline glass–ceramic based on S53P4 45S5 using flow-through method Tris...

A set of molecular dynamics simulations were performed to investigate the effect of cooling rate and system size on the medium-range structure of melt-derived multicomponent silicate glasses, represented by the quaternary 45S5 Bioglass composition. Given the significant impact of the glass degradation on applications of these materials in biomedicine and nuclear waste disposal, bulk structural ...
