The purpose of this study was to analyze the sealing ability of various filling combinations in a 90 days period using fluid transport and glucose penetration models. Premolars (n = 108) were filled with either gutta-percha (groups 1-4) or Resilon (groups 5-8) core materials combined with AH Plus (groups 1, 3, 5, 7) or Epiphany (groups 2, 4, 6, 8) sealers by using cold lateral compaction (groups 1, 2, groups 5, 6) or System B with Obtura II (groups 3, 4, groups 7, 8). The sealing ability of each sample was evaluated through glucose and fluid penetration models. Penetration values of 90 days were statistically analyzed with three-way analysis of variance (ANOVA)and Duncan's Multiple Range tests (p < 0.05). No significant differences were found among the penetration values when the fluid filtration model was used (p > 0.05). On the contrary, statistically significant differences were obtained among the groups with the glucose penetration model (p < 0.05). AH Plus/Resilon/cold lateral compaction group had better sealing ability than the other combinations tested with the glucose penetration model.
本研究旨在使用流体输送和葡萄糖渗透模型分析不同填充组合在 90 天内的密封能力。用冷侧方加压法（第 1、2 组，第 5、6 组）或 System B 配合 Obtura II（第 3、4 组，第 7、8 组）将牙胶（第 1-4 组）或 Resilon（第 5-8 组）芯材与 AH Plus（第 1、3、5、7 组）或 Epiphany（第 2、4、6、8 组）黏固剂混合后填充于前磨牙（n = 108）中。通过葡萄糖和流体渗透模型评估每个样本的密封能力。用三因素方差分析（ANOVA）和 Duncan 多重范围检验（p < 0.05）对 90 天的渗透值进行统计学分析。当使用流体过滤模型时，渗透值之间没有发现显著差异（p > 0.05）。相反，当使用葡萄糖渗透模型时，各组之间获得了统计学上的显著差异（p < 0.05）。与其他测试组合相比，AH Plus/Resilon/冷侧方加压组在葡萄糖渗透模型下具有更好的密封能力。
