Table 1.

Mean±standard deviation of the push-out bond strength of all the groups at different levels of the canal (MPa)

Groups	Level of root
	Coronal	Middle	Apical
1 (5.25% NaOCl)	0.34±0.15*	0.68±1.06*	0.53±0.22*
2 (6.5% PA)	2.22±0.73	1.99±0.33	1.16±0.17#
3 (25% BS)	1.65±0.34	1.84±0.55	1.42±0.30

*Intergroup comparison denotes significantly lesser PBS in Group 1 compared to Groups 2 and 3 (P<0.05), ^#Intragroup comparison denotes significantly lesser PBS at apical third compared to coronal and middle thirds of the root in Group 2 (P<0.05). NaOCl: Sodium hypochlorite, PA: Proanthocyanidin, BS: Bamboo salt, PBS: Push-out bond strength
