To evaluate and compare the laboratory compressive strength (CS), flexural strength (FS), and diametral tensile strength (DTS) of Cention Forte and three bulk fill restorative materials.
A total of 168 specimens were prepared following the manufacturers' instructions and standards for testing CS, FS, and DTS. Mechanical properties of Cention Forte (LC-Cent) were compared to three commercial bulk-fill materials for posterior restorations: Fuji IX Extra (Fuji), Tetric PowerFill (TPF), and Equia Forte HT (Equia). The tests were performed 24 hours after storage in distilled water on a universal testing machine at a crosshead speed of 0.75 mm/minute. Strength values (MPa) were calculated and statistically analyzed by one-way ANOVA and Tukey's post hoc test (P< 0.05).
Analysis showed significant differences between tested materials for CS, FS, and DTS (P= 0.0001). LC-Cent showed the highest mean value for FS (112.8 MPa) with a significant difference compared to Fuji and Equia. DTS (49.2 MPa) of LC-Cent was significantly higher than all tested materials. TPF showed the highest mean value (180 MPa) for CS but without significant difference compared to LC-Cent.
Ion-releasing material Cention Forte, according to obtained results, may serve as a viable alternative for posterior restorations compared to conventional bulk-fill restorative materials.
评估和比较 Cention Forte 与三种块状填充修复材料的实验室抗压强度（CS）、弯曲强度（FS）和直径拉伸强度（DTS）。
根据 CS、FS 和 DTS 的制造商说明和标准，共制备了 168 个样本。将 Cention Forte（LC-Cent）的机械性能与三种用于后牙修复的商用块状填充材料进行比较：富士 IX Extra（Fuji）、Tetric PowerFill（TPF）和 Equia Forte HT（Equia）。测试在万能试验机上以 0.75mm/min 的十字头速度在蒸馏水储存 24 小时后进行。通过单向方差分析和 Tukey 事后检验（P<0.05）计算和统计分析强度值（MPa）。
分析表明，CS、FS 和 DTS 测试材料之间存在显著差异（P=0.0001）。LC-Cent 的 FS 平均值最高（112.8 MPa），与 Fuji 和 Equia 相比有显著差异。LC-Cent 的 DTS（49.2 MPa）明显高于所有测试材料。TPF 的 CS 平均值最高（180 MPa），但与 LC-Cent 相比无显著差异。
根据获得的结果，释放离子材料 Cention Forte 可能是传统块状填充修复材料的一种可行替代物，用于后牙修复。
