Evaluation of Push-out Bond Strength of a Resin Sealer to Dentin after a Final Flush of Three Irrigants.

Aim: To evaluate the push-out bond strength of resin-based sealer to root dentin after a final flush of three different irrigants.

Materials And Methods: Thirty extracted human mandibular premolars were sectioned 4 mm below the cement-enamel junction and 60 horizontal disks of 2 mm from middle one-third of the root were prepared. The disks were immersed in 3% sodium hypochlorite for 1 minute, and after drying the disks, they were finally flushed with the following irrigants: group I-Chitosan solution, group II- juice (MCJ), and group III-ethylenediaminetetraacetic acid (EDTA).
