Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
In the step-down group, root canal shaping will begin at the coronal portion and gradually progress toward the apex, while in the step-back group, preparation will start at the apical portion and move backward toward the coronal area. Postoperative pain will be assessed at multiple time points using a standardized pain scale (e.g., Visual Analog Scale).
The aim of the study is to determine which technique causes less pain after treatment, helping clinicians choose the method that improves patient comfort following root canal therapy.

Step back technique of root canal Vs step down technique of root canal
Arm 1: Step-Down Technique
Arm Type: Experimental Arm Title: Step-Down Root Canal Preparation
Arm Description:
Participants in this arm will receive root canal preparation using the step-down technique, where shaping begins in the coronal portion of the canal and progresses toward the apex. This method is designed to improve irrigation and reduce debris extrusion.
\---
Arm 2: Step-Back Technique
Arm Type: Experimental Arm Title: Step-Back Root Canal Preparation
Arm Description:
Participants in this arm will receive root canal preparation using the step-back technique, where shaping starts at the apical portion and moves step-by-step backward toward the coronal area using progressively larger files. This conventional method serves as the comparison technique.
Step down technique
Step-Down Root Canal Preparation Experimental Step-Down Technique Procedure Root canal preparation starts at the coronal portion of the canal and progresses toward the apex using endodontic files of decreasing size. Aims to improve irrigation, reduce debris extrusion, and minimize postoperative pain.
Step-Back Root Canal Preparation Active Comparator Step-Back Technique Procedure Root canal preparation starts at the apical portion of the canal and progresses stepwise toward the coronal portion using progressively larger files. Serves as the conventional comparator technique to evaluate postoperative pain
Arm 1 Arm Type: Experimental Arm Title: Step-Down Preparation Technique Detailed Description: Pa
Participants in arm 1 will receive root canal preparation using the step-down technique, where shaping begins at the coronal portion of the canal and gradually progresses toward the apex. This method is intended to improve irrigation, reduce debris extrusion, and potentially lower postoperative pain.
Participants arm 2 will receive root canal preparation using the step-back technique, where shaping starts at the apical portion and moves stepwise toward the coronal area using progressively larger files. This conventional method serves as the comparator to evaluate differences in postoperative pain and treatment outcomes.
Step down technique
Step-Down Root Canal Preparation Experimental Step-Down Technique Procedure Root canal preparation starts at the coronal portion of the canal and progresses toward the apex using endodontic files of decreasing size. Aims to improve irrigation, reduce debris extrusion, and minimize postoperative pain.
Step-Back Root Canal Preparation Active Comparator Step-Back Technique Procedure Root canal preparation starts at the apical portion of the canal and progresses stepwise toward the coronal portion using progressively larger files. Serves as the conventional comparator technique to evaluate postoperative pain
