Biophysical and Fluoride Release Properties of a Resin Modified Glass Ionomer Cement Enriched with Bioactive Glasses

The aim of this study was to evaluate the bond strength, microleakage, cytotoxicity, cell migration and fluoride ion release over time from a resin-modified glass-ionomer cement (RMGIC) enriched with bioactive glasses (BAGs) nanohybrid restorative polymer resin agent used as adhesion material in cemented brackets. One hundred twenty bovine lower incisors were divided into three groups: (Transbond Plus Self Etching Primer (TSEP)/Transbond XT (TXT), TSEP/ACTIVA, orthophosphoric acid gel/ACTIVA) brackets bonded. A strength test microleakage applied. applied after 60 days for TXT ACTIVA group. To cytotoxicity migration, viability scratch assay done each p values < 0.05 considered significant. Regarding test, no significant differences found between TSEP/TXT TSEP/ACTIVA. At 6.4 pH, showed higher degree release, which increased pH (3.5), maximum secretion at 30 days. MTT revealed that reduces gingival cells (p 0.001) compared untreated (control group). provides optimal adhesive microfiltration properties, releases substantial amounts ions both neutral media, its biocompatibility is greater than traditional composite systems.
