Endodontist should know about the fracture resistance of endodontic treated teeth in different obturation techniques to make a proper choice for obturation of mechano-chemically prepared root canals. Therefore, it is of interest to compare the fracture resistance of endodontically obturated teeth in five different obturation techniques namely single cone obturation (SCO), cold lateral compaction (CLC), cold free flow condensation, warm vertical compaction, injection molded thermo-plasticized technique. Among experimental categories, maximum fracture resistance was observed in cold free flow condensation technique while minimum fracture resistance was observed in injection molded thermo-plasticized technique. Cold free flow condensation technique using Gutta Flow2 has the potential to be used as obturation technique with minimum fracture resistance. Conventional techniques like CLC and SOC also offered good fracture resistance.
牙髓病医生应该了解不同充填技术下根管治疗后牙齿的抗折性能，以便为机械化学预备的根管选择合适的充填方法。因此，比较五种不同充填技术（即单锥充填法（SCO）、冷侧向加压充填法（CLC）、冷自由流动加压充填法、热垂直加压充填法、注射成型热塑技术）充填根管治疗后牙齿的抗折性能很有意义。在实验类别中，冷自由流动加压充填法观察到的抗折性能最高，而注射成型热塑技术观察到的抗折性能最低。使用Gutta Flow2的冷自由流动加压充填法有可能作为抗折性能最低的充填技术使用。像CLC和SOC这样的传统技术也具有良好的抗折性能。
