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—Morinda citrifolia juice (MCJ), and group III—ethylenediaminetetraacetic acid (EDTA). The disks were filled with AH Plus sealer, and after 7 days, the disks were subjected to push-out bond strength using a universal testing machine. Results: EDTA had the highest push-out bond strength followed by MCJ and then chitosan. Conclusion: Chitosan and MCJ can be used as alternative irrigants as a final flush during the cleaning and shaping of the root canals. Clinical significance: EDTA, chitosan solution, and MCJ are efficient in smear layer removal which thereby increases better sealer penetration and prevents the dislocation of obturating materials.
