The purpose of this study is to compare the mechanical properties (compressive strength (CS) and diametral tensile strength (DTS)) of four different restorative materials: conventional glass ionomer (Fuji IX), ClearFil AP-X, Filtex Z350-XT, and Cention N.
Specimens ( = 80) were prepared from Fuji IX, ClearFil AP-X, Filtex Z350-XT, and Cention N for testing compressive strength and DTS.
Results obtained were subjected to one-way ANOVA and Tukey's test at significance ( < 0.001).
There were significant differences among restorative materials tested. ClearFil AP-X exhibits the highest mechanical properties (CS and DTS) and least values were obtained by the Fuji IX.
Strength is one of the most important criteria for the selection of a restorative material. Stronger materials better resist deformation and fracture, presenting more equitable stress distribution, greater probability, and greater stability of clinical success.

本研究旨在比较四种不同修复材料的力学性能（抗压强度（CS）和径向拉伸强度（DTS））：传统玻璃离子水门汀（Fuji IX）、ClearFil AP-X、Filtex Z350-XT和Cention N。
从Fuji IX、ClearFil AP-X、Filtex Z350-XT和Cention N制备样本（ = 80）以测试抗压强度和DTS。
对所得结果进行单因素方差分析和Tukey检验，显著性水平为 < 0.001。
所测试的修复材料之间存在显著差异。ClearFil AP-X表现出最高的力学性能（CS和DTS），而Fuji IX的数值最低。
强度是选择修复材料的最重要标准之一。更强的材料能更好地抵抗变形和断裂，呈现更均匀的应力分布、更高的临床成功概率和更大的稳定性。
