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.

Interventions

Type	Name	Description
DRUG	root canal irrigation solutions (NaOCl+EDTA, NaOCl+HEDP)	After cavity preparation with sterile burs, rubber dam components were applied to the tooth. The root canal filling material was removed via retreatment files. After the working length was determined, in all the groups, the canals were filled with distilled water. S1were taken from the canal after retreatment. Irrigation protocols were applied for 4 groups. S2 were taken from the canal. Intracanal medicament was placed in the root canal, the cavity was securely sealed. After 14 days,the medicament was removed with 10 mL of 17% EDTA and subsequently irrigated with 5 ml of distilled water, S3 was taken by sterile paper points. The final irrigation was performed according to the group to which the tooth belonged, and S4 was collected as before. the root canals were dried with sterile paper points and filled gutta-percha master cones and sealer.
