Properties of fluoride-releasing light-activated resin cement

摘要

Objectives; fluoroaluminosilicate glass and Poly (acrylic acid) in small water phase was incorporated into resin composite cements to reduce or prevent secondary caries around luted restorations. The purpose of this study was to investigate the physical properties and the amounts of fluoride released from four types of visible light-activated resin cements. Methods: A powder was composed of silanized SiO_2 filler and 4.5 wt./100 (G-4.5), 9.5 wt./100 (G-9.5) or 19.5 wt./100 (G-19.5) fluoroalumi- Nosilicate glass and 0.5 wt./100 reducing agent.
