ABSTRACT


Aim: This Study Aimed To Evaluate The Effect Of The XP-Endo Finisher (XPF), Passive Ultrasonic Irrigation (PUI) And Conventional Irrigation Using Side-vented Needle (SVN) On Post-operative Pain After The Removal Of Calcium Hydroxide Ca(OH)2 And Double Antibiotic Paste (DAP) From Necrotic Mandibular Single Rooted Teeth. Method And Materials: Seventy-two Patients Were Included. After Confirmingthe Diagnosis Clinically And Radiographically In The Firstvisit, Standard Endodontic Treatment Was Performed Using ProTaper Next NiTi Files(Dentsply Maillefer, Ballaigues, Switzerland) Up To X4. Depending On The Type Of Intracanal Medication Used Ca(OH)2 And DAP, Patients Were Assigned Randomly Into 2 Groups (n=36). After One Week, Patients In Each Group Were Randomly Assigned Into 3 Sub-groups (n=12) According To The Method Used For Medicament Removal: XPF, PUI And SVN. Pain Was Assessed Postoperatively After 4, 12, 24, 48, 72 And 96 Hours After The Second Visit Using Modifiedvisual Analogue Scale (VAS). In The Third Visit, Teeth Were Obturated By Lateral Compaction Technique And Resin Sealer. Data Were Statistically Analyzed Using Kruskal Wallis Test Followed By Multiple Mann Whitney U Test With Bonferroni Correction. Intragroup Comparisons Were Done Using Freidman?s Test Followed By Dunn?s Post Hoc Test.

Results: Regarding The Technique Used For Removal Of Intracanal Medication, In Both Groups SVN Showed The Highest Significantpain Score Followed By PUI While XPF Showed The Lowest Mean Value At 4,12,24 And 48 Hours. While, No Significantdifference Obtained Between Them At 72 And 96 Hours. In All Groups, Pain Intensity Was Significantlyhigh At 12 Hours Then Reduced Gradually As The Time Increased.

Conclusions: The Use Of XPF And PUI During The Removal Of Intracanal Medication Results In Less Postoperative Pain.
