Study: NCT06597825

Intervention type: DRUG
Group type: EXPERIMENTAL
Intervention: root canal irrigation solutions (NaOCl+EDTA, NaOCl+HEDP)
Description: 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.
