Fast-setting bioactive cements were developed for the convenience of retrograde fillings during endodontic microsurgery. This in vitro study aimed to investigate the effect of irrigation on the washout of relatively fast-setting materials (Biodentine, EndoCem Zr, and MTA HP) in comparison with MTA Angelus White and IRM in an apicectomy model. Washout resistance was assessed using artificial root ends. A total of 150 samples (30 for each material) were tested. All samples were photographed using a microscope, and half of them were also scanned. The samples were irrigated and immersed in saline for 15 min. Then the models were evaluated. Rinsing and immersing the samples immediately after root-end filling and after 3 min did not disintegrate the fillings made of all tested materials except Biodentine. Root-end fillings made of Biodentine suffered significant damage both when rinsing was performed immediately and 3 min after the filling. Quantitative assessment of washed material resulted in a slight loss of IRM, EndoCem MTA Zr, and MTA HP. MTA Angelus White showed a slightly greater washout. Rinsing and immersion of Biodentine restorations resulted in their significant destruction. Under the conditions of the current study, the evaluated materials, excluding Biodentine, showed good or relatively good washout resistance.
速凝生物活性水门汀是为方便牙髓显微手术中的倒充填而研发的。本体外研究旨在对比MTA Angelus White和IRM，研究冲洗对根尖切除模型中相对速凝材料（Biodentine、EndoCem Zr和MTA HP）冲洗流失的影响。使用人工牙根末端评估冲洗抗性。共测试了150个样本（每种材料30个）。所有样本均用显微镜拍照，其中一半还进行了扫描。样本经冲洗后在盐水中浸泡15分钟。然后对模型进行评估。在根尖充填后立即冲洗和浸泡以及3分钟后冲洗和浸泡，除Biodentine外，所有测试材料制成的充填物均未崩解。Biodentine制成的根尖充填物在充填后立即冲洗和3分钟后冲洗时均遭受了显著破坏。对冲洗掉的材料进行定量评估发现，IRM、EndoCem MTA Zr和MTA HP略有流失。MTA Angelus White的冲洗流失略多。Biodentine修复体的冲洗和浸泡导致其显著破坏。在本研究条件下，除Biodentine外，所评估的材料均表现出良好或相对良好的冲洗抗性。
