ABSTRACT Objectives: The Aim Of This Study Was To Evaluate The Efficacyof The XP-Endo Finisher Filein The Removal Of Calcium Hydroxide From Straight Root Canals Of Single Rooted Teeth In Combination With Either Sodium Hypochlorite Plus Citric Acid Compared With That Of Passive Ultrasonic Irrigation.Materials and Methods: Fifty Two Human Extracted Single Rooted Teeth With Single Straight Root Canals Were Selected And Prepared Using ProTaper Rotary Instruments Up To Size F3 (Dentsply Maillefer, Ballaigues, Switzerland). Calcium Hydroxide (MetaPaste, Meta Biomed Co, Cheongju, Korea) Intracanal Medication Was Placed Inside The Root Canals And Sealed With Temporary Fillingfor 7 Days. The Samples Were Then Randomly Divided Into Two Equal Groups According To The Technique Of Calcium Hydroxide Removal And Each Group Was Further Subdivided Into Two Equal Subgroups According To The Irrigation Protocol. Results: The Combination Of Sodium Hypochlorite + Citric Acid In Comparison To Sodium Hypochlorite Alone Was Significanty Effective In Removing Calcium Hydroxide From The Coronal Third With XP-Endo Finisher While With Passive Ultrasonic Irrigation, The Combination Was Significantlyeffective In Removing Calcium Hydroxide From The Three Root Canal Thirds As Well As The Total Surface Area. Irrespective Of The Irrigation Protocol, There Were No Statistically Significantdifferences Between XP-Endo Finisher And Passive Ultrasonic Irrigation In Removing. Calcium Hydroxide From The Three Root Canal Thirds And The Total Surface Area. Conclusions: It Can Be Concluded That None Of The Tested Methods (techniques Of Activation And Irrigation Protocols Were Able To Completely Remove Calcium Hydroxide From The Root Canal Walls. The Combination Of 5.25% Sodium Hypochlorite + 10% Citric Acid Either With XP-Endo Finisher Or Passive Ultrasonic Irrigation Recorded A Smaller Amount Of Calcium Hydroxide Remnants In The Root Canal Walls In Comparison To 5.25% Sodium Hypochlorite Alone.
