Aim: To evaluate and compare the compressive strength of a new ceramic-reinforced glass ionomer (Amalgomer CR) and resin coated high strength glass ionomer. cement (GIC) (Equia forte) with a nanohybrid composite (tetric N ceram). Methodology: Twenty four maxillary premolar teeth were selected. Selected teeth after cleaning were mounted in acrylic resin blocks exposing the crown. Class II cavities were prepared. Samples were divided into three groups of 8 teeth; • Group 1: Class II cavity restored with Tetric N Ceram composite (control group) • Group 2: Class II cavity restored with amalgomer CR • Group 3: Class II cavity restored with equia Forte Restored samples stored in artificial saliva for 2 weeks and subjected to compressive strength test using the universal testing machine at a cross head speed of 0.5 mm/min. The failure load was recorded. SPSS software was employed for statistical analysis. Mean compressive strength and mean compressive load was calculated. One way analysis of variance (ANOVA) followed by post hoc tests served for comparison of compressive strength among the study groups. The significance level was set at 0.001. Conclusion: Tetric N ceram has a high compressive strength compared to amalgomer CR and equia forte. It can be concluded that tetric N ceram may be a better posterior restorative in comparison with Amalgomer CR and Equia Forte.
