Abstract

Amorphous calcium phosphate (ACP)/acrylic matrix composites have the potential to promote remineralization and/or prevent demineralization of tooth structures by hydroxyapatite (HAP) formation. The goal of this study was to evaluate the effects of compositional and structural variations of photopolymerizable monomer systems on the long-term release of calcium and phosphate ions from ACP composites. The monomer systems evaluated were: (1) Bis-GMA/TEGDMA, (2) Bis-GMA/TEGDMA/HEMA, (3) UDMA with 0 %, 6.6 % or 13.2 % HEMA, and (4) PMGDMA/ TEGDMA. Visible light polymerizable composites comprised by mass fraction of 60 % matrix and 40 % ACP. Whereas Bis-GMA/TEGDMA composites gave extremely low levels of ion release, the UDMA composites gave moderate sustainable release of ions. High, sustainable levels of ion release were obtained from the HEMA-containing composites. The carboxylic acid matrix composite based on PMGDMA initially gave high ion release, but this was not sustainable because of Ca-binding and internal ACP conversion to HAP.
