The tubular penetration and adaptation of the sealer are important factors for successful root canal filling. The aim of this study was to evaluate the tubular penetration depth of four different sealers in the coronal, middle, and apical third of root canals as well as the adaptation of these sealers to root canal walls. 50 single-rooted teeth were prepared in this study. Forty-eight of them were filled with different sealers (Cortisomol, iRoot SP, AH-Plus, and RealSeal SE) and respective core filling materials. Then the specimens were sectioned and scanning electron microscopy was employed to assess the tubular penetration and adaptation of the sealers. . Our results demonstrated that the maximum penetration was exhibited by RealSeal SE, followed by AH-Plus, iRoot SP, and Cortisomol. As regards the adaptation property to root canal walls, AH-Plus has best adaptation capacity followed by iRoot SP, RealSeal SE, and Cortisomol. . The tubular penetration and adaptation vary with the different sealers investigated. RealSeal SE showed the most optimal tubular penetration, whereas AH-Plus presented the best adaptation to the root canal walls.
根管的贯穿和封闭剂的适应是根管充填成功的重要因素。本研究的目的是评估 4 种不同根管封闭剂在根管冠、中、根尖 3 区的根管贯穿深度以及这些封闭剂对根管壁的适应情况。本研究共预备了 50 颗单根牙。其中 48 颗牙用不同的封闭剂（Cortisomol、iRoot SP、AH-Plus 和 RealSeal SE）和相应的核填充材料进行填充。然后将标本进行切片，采用扫描电子显微镜评估封闭剂的根管贯穿和适应情况。结果表明，RealSeal SE 的最大贯穿深度最大，其次是 AH-Plus、iRoot SP 和 Cortisomol。至于对根管壁的适应能力，AH-Plus 的适应能力最好，其次是 iRoot SP、RealSeal SE 和 Cortisomol。不同的封闭剂根管的贯穿和适应情况不同。RealSeal SE 表现出最佳的根管贯穿效果，而 AH-Plus 对根管壁的适应能力最好。
