Background: Postendodontic pain (PEP) is defined as pain of any degree that occurs after the initiation of randomized controlled trial. The development of postoperative pain is usually due to acute inflammatory response in the periradicular tissues. Aim: The aim of the study was to evaluate and compare the influence of different instrumentation techniques on PEP following a single-visit root canal treatment. Materials and Methods: Ninety-nine patients were divided into three groups (99 = 33 × 3): Group 1, Control (ProTaper Universal Hand); Group 2, Rotary (ProTaper Universal Rotary); and Group 3, Reciprocating (WaveOne Gold). A Visual Analog Scale questionnaire was given at the end of the appointment to be filled at 6, 12, 24, and 48 h. Results: Group 2 (Rotary technique) (ProTaper Universal Hand) showed minimum PEP with a mean pain score of 2.0 at the end of 48 h, which was statistically significant (P < 0.0001). Conclusion: Different instrumentation techniques/systems used for biomechanical preparation had an effect on PEP. Minimum PEP was reported by patients in Group 2 (ProTaper Universal Rotary) when compared with those in Group 3 (WaveOne Gold) and Group 1 (ProTaper Universal Hand).
