Time-Dependent Effect of Chitosan Nanoparticles as Final Irrigation on the Apical Sealing Ability and Push-Out Bond Strength of Root Canal Obturation

Table 2

Mean and standard deviation of the pushout bond strength of the root canal obturation (in MPa).

Final irrigation	Application time	Mean ± standard deviation
17% EDTA	1	6.24 ± 1.66^a
	3	9.37 ± 1.06^b
0.5% chitosan nanoparticle	1	7.89 ± 2.02^a
	3	10.19 ± 1.57^b

Different letters indicate that there were statistically significant differences.
