Abstract：
UNASSIGNED: To evaluate and compare volume and homogeneity of the three different root canal obturation systems.
UNASSIGNED: Single-rooted premolar (n = 24) teeth samples were selected, and crowns were removed for standardization. Four groups are divided randomly as (n = 6), namely: For group I (single-cone gutta-percha obturation), group II (Beefill 2 in 1 obturation), group III (GuttaCore obturation), group IV (GuttaFlow bioseal obturation) and the root canal were subjected to prepare till X3 (protaper next) and subjected to micro-CT imaging. After completion of obturation, the image was taken by using micro-CT imaging. This is to evaluate the volume of filled obturation material in the canal space and the voided area sections, viz. the apical, middle, coronal, and third sections.
UNASSIGNED: Group III (GuttaCore obturation) showed the least significant mean of the difference in relation to the volume of the canal obturation (81.148). The least mean significant difference in area of voids in the canal region for apical (0.00133), middle (0.00233), and coronal thirds (0.00533). The most statistically significant difference is in the apical and middle thirds root canal space.
UNASSIGNED: All the experimental groups showed significant differences in volume and voids in the obturation at three different levels, and the GuttaCore obturation systems occupied more of the volume with less voids in the prepared root canal space.

摘要：
■评估和比较三种不同根管闭塞系统的体积和均匀性。
■选择单根前磨牙（n=24）牙齿样本，为了标准化，删除了牙冠。随机分为四组(n=6)，即：对于I组（单锥体牙胶闭塞），II组（Beefill2in1闭塞），组III（GuttaCore闭塞），对IV组（GuttaFlow生物封堵）和根管进行准备，直到X3（下一个），并进行显微CT成像。封堵完成后，图像采用显微CT成像。这是为了评估运河空间和空隙区域部分中填充的闭塞材料的体积。viz.顶端，中间,日冕,和第三部分。
■第III组（GuttaCore闭塞）显示出与运河闭塞体积有关的差异的最小平均值（81.148）。根尖管区空隙面积的最小平均显著性差异(0.00133),中间（0.00233），和冠状三分之一（0.00533）。统计学上最显著的差异是根尖和中三分之二根管空间。
■所有实验组在三个不同水平上显示出闭塞的体积和空隙的显着差异，GuttaCore闭塞系统占据了更多的体积，在准备好的根管空间中空隙较少。
