Abstract
Background: To compare the incidence of postoperative pain and analgesic intake on the administration of passive ultrasonic irrigation (PUI) using IrriSafeTM, laser-activated irrigation (LAI) using Er:Cr: YSGG in comparison to conventional needle irrigation (CNI) in participants diagnosed with symptomatic irreversible pulpitis (SIP). Material and Methods: In this randomised double-blinded parallel trial, 75 participants requiring root canal treatment in mandibular first molars diagnosed with SIP were enrolled. A 10 cm visual analogue scale (VAS) was used for pain assessment and patients presented with a preoperative pain score of 5 cm and above were only selected. After biomechanical preparation, the final irrigation protocols varied based on the irrigation protocol employed. In CNI, intracanal irrigation was conducted without agitation using a 31G side vented needle. In PUI, irrigant activation was conducted using IrriSafeTM and in LAI, irrigant activation was conducted using a pulsed Er:Cr: YSGG (2940 nm) laser with radial firing tip (RFT - 2). The pain scores and analgesic intake were assessed postoperatively after obturation at 6, 24 and 48 h. Results: <0.05) respectively. Conclusions: Endodontics, Root canal irrigants, Postoperative Pain, Passive ultrasonic activation, Laser ultrasonic activation.
