ABSTRACT Carious lesions located at the margins of resin composite restorations and on unrestored proximal tooth surfaces in contact with resin composite restorations is an undesirable occurrence that can necessitate restorative intervention. Significantly however, several in vivo and in vitro studies have shown that should a composite restoration have fluoride releasing capability, the incidence of caries associated with resin composite restorations at these locations has the potential to be reduced. Further, it has been speculated that the inclusion of Pre-reacted glass ionomer (PRG) partic

It is desirable for a dental restorative material to have bioactive and bonding properties. This study focuses on the synthesis of a covalently-linked polyurethane/nanohydroxyapatite (PU/nHA) composite and evaluates its chemical, physical, thermal and biochemical characteristics. nHA powder was produced from the sol-gel and novel composite material was chemically prepared by utilising solvent polymerisation. The resulting composites were analysed by chemical, thermal, and mechanical characterisations and electrospun to form fibre mats. The composites were hydrolytically degraded in deionised w
