Abstract

Objectives: To assess the compressive strength of commercial resin-modifi ed glass ionomer cement with conventional glass ionomer cement.
Methods and materials: Compressive strength of two conventional glass ionomer cement (Low viscosity - GC Fuji IX GP® and high viscosity - ChemFil Rock®) and two resin-modifi ed glass ionomer cements (Auto-cure - Fuji-Plus® and Light activated - Fuji II LC®) were investigated at 24°C and 37°C after 1 and 28 days. All materials were mixed according to manufacturer’s instructions. The samples were made in 6mm height and 4mm in diameter. Universal Testing Machine (Instron, M30K) at crosshead speed of 0.5mm/min was used according to ISO 9917-1:2007 (E) standards to evaluate compression strength. Paired T-test was used to fi nd statistical difference between the commercial groups, keeping p value of ≤ 0.05 as signifi cant.
Results: Resin-modifi ed Glass ionomer cement showed low compressive strength (113 ±8 MPa) as compared to the conventional Glass ionomer cement (179 ±20 MPa) at both room temperature as well as at body temperature. Furthermore, ChemFill Rock® has the highest compressive strength, whereas Fuji-II® has the lowest compressive strength at 1-day and 28 day respectively.
Conclusion: Compressive strength was low for resin-modifi ed Glass ionomer cement as compared to conventional glass ionomer cement. Chemifi l-rock® material has achieved maximum compressive strength among all the commercial materials.
