Effect Of Different Sodium Hypochlorite Concentrations On Intracanal Substance P, CGRP And Opiorphin Levels And Postoperative Pain During Root Canal Retreatment

Summary

This randomized clinical study aims to evaluate the effect of different sodium hypochlorite concentrations (1%, 2.5%, and 5.25%) used during root canal retreatment on intracanal levels of Substance P, CGRP, and Opiorphin, as well as postoperative pain. Patients requiring non-surgical root canal retreatment will be randomly assigned to one of three irrigation concentration groups. Intracanal samples will be collected before and after irrigation to measure neuropeptide levels. Postoperative pain will be assessed using a visual analog scale (VAS) at predetermined time intervals. The results of this study may help clarify the relationship between irrigant concentration, inflammatory mediators, and postoperative pain following root canal retreatment.
