ABSTRACT
It Is Widely Known That The Prepared Canals Can Never Be Sterile Before Obturation, No Matter How Potent The Antibacterial Irrigants Or Intracanal Medications Are. There Are Currently Two Means To Reduce Bacterial Persistence And Reinfection In The Canals. We Can Either Fill The Canals With Antibacterial Agents In Many Visits Or Immediately Obturate The Canals, To Decrease The Space For Bacterial Colonization, In A Single-visit Approach. The Goal Of The Present Study Was To Compare The Intensity Of Postoperative Pain Following One-visit Versus Two-visit Root Canal For Instrumentation Of Root Canals. Methods: Fifty Patients Who Fulilled Specific Inclusion Criteria Were Assigned To Two Groups According To The Root Canal Instrumentation Technique Used, One-visit Versus Two-visit Root Canal Treatment Was Carried Out And The Severity Of Postoperative Pain Was Assessed By Visual Analogue Scale (VAS) Scores After The Session Until Complete Pain Relief Was Achieved.

Results: Mean Of VAS Scores Between The Two Groups And Within The Same Group At Different Follow Up Periods (6, 12, 24 And 48 Hours) Showed No Statistically Significant Difference.
