| Abstract | ||
| This study was aimed to compare calcium aluminate glass ionomer cement (Ceramir, Doxa Dental AB) as a new formulation with conventional and resin modified glass ionomer cements (Riva SDI). A total number of 90 samples were used in this study. The samples were divided into 3 main groups according to type of materials (each group was 30 samples), they were then subdivided into two subgroups according to the test performed with 15 samples in each subgroup. They were tested for their compressive strength and shear bond strength. Results: Data analysis was performed using One way ANOVA followed by Tukey’s pair-wise .P values ≤0.05 are considered to be statistically significant in all tests, it was found that resin modified glass ionomer cement recorded the highest statistically significant mean values of compressive strength and shear bond strength, while the lowest values were recorded for the conventional glass ionomer in compressive strength while ceramir recorded the lowest shear bond strength. Conclusion: Calcium aluminate modified glass ionomer cement recorded an intermediate compressive strength mean value between resin modified and conventional glass ionomer cements, it also recorded the lowest shear bond strength mean value compared to resin modified glass ionomer and conventional glass ionomer cement. | ||
