Abstract

Objectives: This in vitro research was performed to assess the flexural and compressive strengths of EQUIA, GC Gold Hybrid (GH), and conventional glass ionomer cement (GIC) restorative materials. Materials and methods: This study compares three restorative.

Materials: group I-EQUIA Forte GIC, group II-GC GH, and group III-conventional GIC for compressive and flexural strength evaluation. With a specially made Teflon mold, thirty-six cylindrical test specimens measuring 4 mm × 5 mm in dimension were created. They were then placed in 20 mL of deionized water and kept at 37°C for 3 hours every day for 30 days. Later, they were subjected to compressive strength and flexural strength using the universal testing machine. Statistics were used to examine each and every result.

Result and conclusion: EQUIA had the highest average compressive strength and flexural strength, whereas traditional GIC restorative material had the lowest.
