This Study Compares Two Different Ways of Cleaning and Shaping Root Canals During Root-canal Treatment: the Step-down Technique and the Step-back Technique. Iu Want to Find Out Which Method Causes Less Pain After the Procedure. Patients Will be Randomly Placed Into One of the Two Groups, Treated Wit

This randomized clinical trial aims to compare the step-back and step-down root canal preparation techniques in patients with pulp necrosis. The study will evaluate which technique results in less postoperative pain. Participants will be randomly assigned to one of the two groups. Pain intensity will be recorded at specific time points after the procedure using a standardized pain scale. The goal is to identify the technique that provides better patient comfort after root canal treatment.This study is a randomized clinical trial designed to compare the effects of two root canal preparation techniques-step-back and step-down-on postoperative pain in patients diagnosed with pulp necrosis. Participants will be randomly assigned to one of the two groups.
