Introduction This in vitro study investigated the dislodgement resistance of EndoSeal MTA, a new pozzolan-containing calcium silicate-based material, in comparison with ProRoot MTA and Biodentine in the presence and absence of contamination with blood. Methods Standard furcal perforations were created in 180 human mandibular first molars. The teeth were randomly allocated to 12 groups of 15 each. ProRoot MTA, Biodentine, and EndoSeal MTA were used to repair the perforations. In half of the samples, the walls of the perforated areas were contaminated with blood, whereas saline was injected into the other half. A push-out test was performed using a universal testing machine after 24 hours or 7 days. To evaluate failure patterns, the samples were split into half and were examined under a stereomicroscope at a 20x magnification. Data were analyzed using three-way analysis of variance, Tukey test, and Student's t-test. Results At both time intervals and in the presence and absence of contamination with blood, ProRoot MTA and Biodentine had significantly higher retention values than EndoSeal MTA (p < 0.001). Contamination with blood had no effect on EndoSeal MTA; however, it negatively affected the dislodgement resistance of Biodentine at 24 hours and ProRoot MTA at both time intervals (p < 0.05). Time significantly affected only the bond strength of the uncontaminated groups (p > 0.001). The most common type of failure was mixed for ProRoot MTA and Biodentine, whereas it was cohesive for EndoSeal MTA. Conclusions ProRoot MTA and Biodentine showed higher values of bond strength than EndoSeal MTA and may thus be better options for the repair of root perforations.

与 ProRoot MTA 和 Biodentine 相比，在有血和无血的情况下评估新型火山灰基水泥 (EndoSeal MTA) 的抗移位性

简介 这项体外研究调查了 EndoSeal MTA（一种新的含火山灰的硅酸钙基材料）与 ProRoot MTA 和 Biodentine 在存在和不存在血液污染的情况下的抗移位性。方法 在 180 颗人类下颌第一磨牙中创建标准的牙根穿孔。这些牙齿被随机分配到 12 组，每组 15 颗。ProRoot MTA、Biodentine 和 EndoSeal MTA 用于修复穿孔。在一半的样本中，穿孔区域的壁被血液污染，而另一半则被注射了盐水。在 24 小时或 7 天后使用通用试验机进行推出试验。为了评估失效模式，将样品分成两半，并在 20 倍放大倍率的立体显微镜下进行检查。使用三因素方差分析、Tukey 检验和学生 t 检验对数据进行分析。结果 在两个时间间隔以及存在和不存在血液污染的情况下，ProRoot MTA 和 Biodentine 的保留值显着高于 En​​doSeal MTA (p < 0.001)。血液污染对 EndoSeal MTA 没有影响；然而，它对 Biodentine 在 24 小时和 ProRoot MTA 在两个时间间隔的抗脱落性产生了负面影响（p < 0.05）。时间仅显着影响未污染基团的结合强度（p > 0.001）。ProRoot MTA 和 Biodentine 最常见的失败类型是混合的，而 EndoSeal MTA 是内聚的。
