Background: Most often used intracanal medicament is calcium hydroxide (Ca(OH)2). Removal of Ca(OH)2before obturation is mandatory. Different irrigation solutions and devices were tested in the previous study for this purpose. Aim: The aim of this study was to evaluate the comparative efficacy of different irrigation techniques in removing intracanal medicament using cone-beam computed tomography (CBCT). Materials and Methods: Cleaning and shaping was carried out in 42 freshly extracted single-rooted mandibular first premolars using Protaper Rotary Files. Intracanal medicament (silicone oil-based Ca(OH)2paste) was placed and left for 2 weeks in the root canal. Medicament was then removed by five different irrigation techniques: EndoActivator, EndoVac, ultrasonic irrigation with Endo-U-File, F-file, and Max-i-Probe needle. Changes in volume percentage were measured using CBCT and results were statistically analyzed using Levene's statistics and ANOVA. Results: Remnants of Ca(OH)2were found in all experimental groups. No significant difference was detected among the groups. F-file showed maximum removal efficacy of approximately 48%. Conclusion: (1) There is no statistically significant difference between any irrigation technique for removal of oil-based Ca(OH)2. (2) F-file demonstrated better results among all the other systems.
