This in-vitro study aimes to compare the microleakage of different restorative materials namely EQUIA Forte (GC, Japan), Tetric Evoceram (Ivoclar Vivadent, Liechtenstein), and Activa BioACTIVE.
A standardized class V cavity has been created on the buccal surface of 40 sound premolar teeth. The cavity had the following measurements: 3 mm buccolingual height, 2 mm axial depth, and 4 mm mesiodistal width. The gingival margin was 1mm below the cementoenamel junction, whereas the coronal margin was on the enamel with cavosurface margins were butt joints all around. Four groups of teeth were restored according to the restorative materials. Under a stereomicroscope, the dye penetration test was used to measure the microleakage after thermocycling of the teeth. Data were compared using Kruskal-Wallis H and Mann-Whitney U Tests.
Occlusal and gingival margins did not show statistically significant differences among the four groups, but an intragroup analysis revealed a significant difference.
The type of restorative material did not appear to have a substantial impact on microleakage, according to the findings of the current investigation.
本体外研究旨在比较不同修复材料的微渗漏情况，这些材料分别为 EQUIA Forte（日本 GC 公司）、Tetric Evoceram（列支敦士登 Ivoclar Vivadent 公司）和 Activa BioACTIVE。
在 40 颗健康前磨牙的颊面制备标准化的 V 类洞。该洞的尺寸如下：颊舌向高度 3mm，轴向深度 2mm，近远中宽度 4mm。龈缘位于牙骨质釉质界下方 1mm，而冠方边缘位于釉质上，洞缘斜面各处均为对接。根据修复材料将牙齿分为四组。在体视显微镜下，采用染料渗透试验测量牙齿热循环后的微渗漏情况。使用 Kruskal-Wallis H 检验和 Mann-Whitney U 检验对数据进行比较。
四组之间的咬合面和龈缘未显示出统计学上的显著差异，但组内分析显示存在显著差异。
根据本研究的结果，修复材料的类型似乎对微渗漏没有实质性影响。
