Aim: The aim of this study is to compare and evaluate compressive strength (CS) and diametral tensile strength (DTS) of a conventional glass ionomer cement (GIC) and a glass hybrid GIC. Materials and methods: Five samples each were prepared of GC Fuji IX and EQUIA Forte cements for CS testing and five samples of each material for tensile strength testing. Specimens were subjected to a universal testing machine. Comparison of CS and DTS among two study groups was made using an independent t-test for each. Level of significance was set at p ≤ 0.05. Results: Both test values were on the higher side for EQUIA Forte cement as compared to conventional GIC (p ≥ 0.05). However, the differences in values were not statistically significant. Conclusion: EQUIA Forte can serve as an alternative to conventional GIC in stress-bearing primary teeth areas. Considering several factors like cost-effectiveness, surface to be restored, moisture contamination, and time considerations, the material of choice can be tailored to one's needs. Clinical significance: EQUIA Forte can serve as a viable alternative to conventional GIC because of its improved qualities.
