Abstract | ||||
Aim: The aim of this study was to compare Protaper Universal retreatment files, M-Pro, and Twisted files in retreatment. Methodology: Experimental groups were divided into three group; Group I: Protaper Universal Retreatment (PTU; Dentsply Maillefer, Ballaigues, Switzerland), Group II: M-Pro (Innovative Material and Devices, ShangHai, China), and Group III: Twisted File (TF; SybronEndo, Orange, CA). Each group was evaluated for time to reach the working length, amount of debris extruded during retreatment. Data were then collected, tabulated and statistically analyzed. Results: Statistical analysis showed that TF recorded the least time to reach the working length, while M-Pro showed the highest amount of debris extruded. Conclusion: Under the condition of the current study, TF was faster than M-Pro and PTU to perform gutta-percha removal in the retreatment of teeth. The use of M-Pro in retreatment increased the amount of apically extruded debris. | ||||
