| Abstract Aim: This research focused on assessing impact of three distinct final irrigation protocols.; Sodium hypochlorite (NaOCl) only, NaOCl followed by Ethylenediaminetetraacetic acid (EDTA) and NaOCl followed by EDTA then NaOCl again on push-out bond strength (POBS) of AH-plus sealer to root dentine. Methodology: Forty-five mandibular premolar teeth were decoronated and instrumented by ProTaper universal (Dentsply Maillefer, Ballaiques, Switzerland) rotary files up to F4. specimens were divided into three groups (n=15) according to final irrigation protocol (NaOCl, followed by EDTA and NaOCl followed by EDTA then NaOCl again). Lateral compaction technique was utilized to obturate all canals. POBS was assessed by universal testing machine. Results: NaOCl followed by EDTA showed greatest value of POBS compared to NaOCl only. Where NaOCl followed by EDTA then NaOCl showed lowest value of POBS. Conclusion: Final irrigation protocol NaOCl followed by EDTA then NaOCl again decreased AH plus POBS while NaOCl followed by EDTA enhanced its bonding strength. | ||
