Summary
Sodium hypochlorite (NaOCl), the most commonly used irrigation solution during chemomechanical preparation, plays a significant role in eliminating bacteria within root canals. Additionally, after preparation with different concentrations of NaOCl, 30% to 70% resistant bacteria were observed in the root canals. For this reason, new protocols have been developed to increase the effectiveness of NaOCl in chemomechanical preparation and to support disinfection within root canals. Recently, etidronic acid (1-hydroxyethane 1,1-diphosphonic acid \[HEDP\]), a biocompatible chelating agent, has emerged as an alternative irrigation solution. It has been suggested to combine and use this solution with NaOCl.
This study aims to evaluate the antimicrobial effectiveness of NaOCl in the root canal, which is used in combination with HEDP or sequentially with Ethylenediaminetetraacetic acid (EDTA) in the final irrigation after retreatment. Additionally, the effect of activation with Endoactivator (EA) on microbial reduction was assessed.
