Propolis is a promising natural product with many dental applications. The Aim of the study was to evaluate qualitatively and quantitatively some physical properties of glass ionomer after the addition of propolis.Materials and Methods: Two groups of specimens have been made, the control group was conventional glass ionomer restorative material (Medifil, PROMEDICA, Germany). Second group was conventional glass ionomer containing ethanolic extract of propolis (EEP). The setting time was measured using an indenter of mass 400 gm and diameter 1 mm. For measuring water sorption and solubility, 20 specimens (20x1.5mm) were prepared. Specimens were suspended in bottle containing 50 ml of distilled water for 1 week. After 1 week, the specimens were removed from the bottle and weighed (m2). Specimens were dehydrated in incubator at 37°C for 24 hours and were reweighed (m3). Ten specimens (9x2mm) were prepared where fluoride release was measured using fluoride selective electrode after 1,7,14 and 21 days. Twenty specimens (4x6mm) were prepared to measure compressive strength using universal testing machine. For bond strength, twenty teeth discs were prepared. A central cylindrical cavity was prepared in each specimen where it was packed by the mixed material and then bond strength was measured using push out test.Results: There was no significant difference between the two groups regarding water solubility, fluoride release and bond strength. On the other hand, there was significant increase in setting time and water sorption in group containing EEP, while there was significant decrease in compressive strength in group containing EEP.Conclusion: It can be concluded that glass ionomer containing propolis would be promising material for restoration provided that further investigations and modifications are done.
