Abstract : Aim: The purpose of this study is to evaluate the efficacy of a new rotary instrument XP-Endo finisher in removing calcium hydroxide Ca(OH)2 intracanal medicament from inside the root canal in combination with different irrigation regimens. Data gathering was done using micro computed tomographic evaluation (Micro-CT). Materials and methods: A total of 32 root canal in birooted human maxillary premolar were selected for the study. All root canals were prepared using ProTaper Next rotary system up to X3. The canals were then filled with calcium hydroxide Ca(OH)2. All teeth were then scanned using micro-CT machine to measure the volume of calcium hydroxide Ca(OH)2 present inside the canals. After that, the teeth were randomly allocated into 2 experimental groups (n = 16 canals) according to the type of file used for calcium hydroxide Ca(OH)2 removal. Each group was further subdivided into two subgroups based on the irrigation protocol used. In group A, Ca(OH)2 was removed by the master apical file (X3). In group B, Ca(OH)2 was removed using XP finisher file. In half of group A and B (n=8) syringe irrigation (SI) was used. Passive ultrasonic irrigation (PUI) was used in the other half of groups A and B. After removal of calcium hydroxide Ca(OH)2, the teeth were scanned again to measure the volume of calcium hydroxide Ca(OH)2 remaining inside the canals. All data were analyzed using two-way ANOVA with Tukey’s PostHoc test. Results: Remnants of Ca(OH)2 were found in all experimental groups. The percentages of remaining Ca(OH)2 in the apical thirds of all canals were higher compared to the middle and coronal thirds in all groups (P < 0.05). XP finisher file in conjunction with PUI significantly removed more Ca(OH)2 than XP with SI and X3 with SI. The mean percentage of remaining Ca(OH)2 was higher in the group without PUI. Conclusion: The combination of XP finisher and passive ultrasonic irrigation was significantly effective in the removal of Ca(OH)2 from root canals in apical third.
