OBJECTIVES
This 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.
目的
本研究旨在评估 EQUIA、GC 金混合（GH）和传统玻璃离子水门汀（GIC）修复材料的抗折强度和抗压强度。材料与方法：本研究比较了三种修复材料。
材料
第一组为 EQUIA Forte GIC，第二组为 GC GH，第三组为传统 GIC，用于抗压强度和抗折强度评估。使用特制的聚四氟乙烯模具制作了 36 个尺寸为 4 毫米×5 毫米的圆柱形测试样本。然后将它们置于 20 毫升去离子水中，每天在 37°C 下放置 3 小时，持续 30 天。之后，使用万能试验机对它们进行抗压强度和抗折强度测试。运用统计学方法检验各项结果。
结果与结论
EQUIA 的平均抗压强度和抗折强度最高，而传统 GIC 修复材料的强度最低。
