Introduction: Calcium hydroxide must be completely removed from the root canal before the endodontic therapy. One of the methods to remove calcium hydroxide is XP-endo finisher file which has conflicting results. This study aimed to compare the efficacy of XP-endo finisher in removing calcium hydroxide with other irrigation methods. Materials and methods: In this experimental in vitro study, 48 teeth were selected. Each tooth was split longitudinally. Standardized grooves were prepared in the middle and apical third of the canals and then were filled with calcium hydroxide. The roots were randomly divided into three groups according to calcium hydroxide removal methods: XP-endo finisher, passive ultrasonic irrigation, and syringe needle irrigation. The amount of remaining medicament was evaluated using a scoring system. Chi-square was used to study the difference between the qualitative variables. The significant level was P < 0.05. Results: In the middle part, XP-endo finisher removed calcium hydroxide significantly higher than other methods (P = 0.005). In the apical part, no significant difference was observed among the groups (P = 0.47). Conclusion: All methods removed more calcium hydroxide in the middle than the apical part. In the middle part, XP-endo finisher removed calcium hydroxide more than the other methods from the root canals.
