Effectiveness of Three Different Irrigation Methods During a Root Canal Treatment
Sponsor: Pakistan Institute of Medical Sciences
Summary
This study aims to compare the effectiveness of three root canal irrigation techniques-Conventional Needle Irrigation (CNI), Side-Vented Needle (SVN), and Ultrasonic Irrigation (UI)-in achieving irrigant penetration into the apical third of the root canal. Since conventional irrigation often fails to adequately clean complex root canal anatomy, the study evaluates whether activation methods improve irrigant penetration. A randomized controlled trial will compare these three techniques using extracted single-rooted mandibular premolars. A radiopaque dye mixed with sodium hypochlorite will be used to measure irrigant penetration on digital radiographs, and the results will be statistically analyzed to determine the most effective irrigation method.

Conditions
Interventions
Conventional Needle
Conventional syringe irrigation will be performed using a 27-gauge needle to deliver the radiopaque sodium hypochlorite solution into the prepared root canal. No additional activation technique will be used during irrigation
Side Vented Needle
Irrigation will be carried out using a side-vented needle to introduce the radiopaque sodium hypochlorite solution into the prepared canal. The side-vented design is intended to improve irrigant distribution within the canal while minimizing direct apical flow
Ultrasonic Irrigation
Following canal preparation, the radiopaque sodium hypochlorite solution will be activated using an ultrasonic device to enhance irrigant movement throughout the root canal system before radiographic evaluation of penetration depth.
