Evaluation of shear bond strength of methacrylate- and silorane-based composite resin bonded to resin-modified glass-ionomer containing micro- and nano-hydroxyapatite

ABSTRACT

Statement of the Problem: The adhesion of resin-modified glass-ionomer [RMGI] to composite resin has a very important role in the durability of sandwich restorations. Hydroxyapatite is an excellent candidate as a filler material for improving the mechanical properties of glass ionomer cement
