This study evaluated the chemical or structural changes of Si-based glass particles contained in cured resin polymers after long-term (150 and 300 days) test solution storage. Three types of glass particles and a glass-ionomer cement were used in this study. The surface of resin disks (glass/polymer composites) were examined by morphological and chemical analysis. Various types of remineralization products were observed on the disk surfaces with SEM over 150 days for two of four groups. The XRD analysis showed crystals deposited on the resin matrix had calcium carbonate (CaCO_3). The EDX analysis showed that Ca- and Si-rich layer was formed on the specimen surfaces after storage. The ability of remineralization depends on type of glass particles.
