Hygroscopic bioactive light-cured composite promoting dentine bridge formation.

ABSTRACT: A light-cured bioactive composite, TheraCal LC, is easy to handle and fast-setting. But poor water absorption restricted its bioactivity when applied in direct pulp capping (DPC). Enhancing the water absorption of resin-based bioactive materials may be key to optimizing biomineralization procedure of light-cured bioactive materials. We constructed a hygroscopic, light-cured bioactive composite made up of bioactive glass (BG), poly (ethylene glycol) (PEG) and resin in this study. BG was encapsulated into a porogen (i.e. PEG) and mixed into resin matrix. Inductively coupled plasma showed that light-cured BG (LC-BG) exhibited faster ion release and more ion exchange than TheraCal LC did. The formation of macropores and hydroxyapatite crystal coatings on the BG microparticles was observed usin
