Abstract:

In this in vitro study, the effects of glass ionomer cement, resin modified glass ionomer cement and polyacid modified resin composite used in clinical practice on gingival fibroblast cells were investigated. For MTT test, the substructures of three different filling materials' were incubated with gingival fibroblast cells for 24 and 72 hours. In MTT test analysis, fibroblast attachment on poliacid modified resin composite filling material was excessive after 24 hours but decreased after 72 hours (p<0,05). Fibroblast attachment on resin modified glass ionomer cement was lower than other filling materials after 72 hours. When cell proliferation percentages of all filling materials were compared with control group (glass) after 24, 72 hours, it was observed that the difference was statistically significant (p>0,05). In addition to our in vitro research results, the chemical surface analysis techniques, measurement of release of elements and physical surface characterization and analysis of microstructure and porosity can provide a better understanding of the biological response of filling materials.
