Abstract

This study explores how a) resin grafting potential for amorphous calcium phosphate (ACP) and b) particle size of ACP affects physicochemical properties of composites. Copolymers and composites were evaluated for biaxial flexure strength (BFS), degree of vinyl conversion (DC), mineral ion release and water sorption (WS). Milled ACP composites were superior to unmilled ACP composites and exhibited 56 % and 79 % higher BFS values (dry and wet state, respectively). The average DC of copolymers 24 h after curing was 80 %. DC of composites diminished 13.6 % (unmilled Zr-ACP) or 7.3 % (milled Zr-ACP) compared to corresponding copolymers. The WS increased as follows: copolymers
