Glass-Ionomer Cements for Medical Applications
Glass-ionomer cements have recently been developed for use as bone cements in otorhinolaryngology. However, they would benefit from further improvements to their radio-opacity and handling properties. A systematic substitution of SrF2 for CaF2 within a commercial glass composition (SerenoCEM®) was carried out. The glass compositions were verified using x-ray fluorescence and the glass morphology was observed using electron microscopy. A variety of methods were applied to study the working and setting times of the cement, including the Gilmore needle (dental standard BS 29917 & 6039) and calorimetry.
